If you like it loud, protect your speakers from bass distortion and enjoy cleaner sound with Bass Blockers. Each Bass Blocker handles up to 50 watts RMS with a 6 dB per octave roll-off. You'll find some general guidelines below for matching Bass Blockers to speaker size. For smaller speakers (3-1/2"s, 4"x6"s, 4"s), the 600 Hz Bass Blockers work well with low-powered systems, while the 800 Hz Blockers are a better choice for high-power applications.
Speaker Size Cut-off Frequency
6-1/2", 5"x7"/6"x8" — 150 Hz
5", 5-1/4" — 300 Hz
3-1/2", 4", 4"x6" — 600 Hz (low power)
3-1/2", 4", 4"x6" — 800 Hz (high power)
These models come fitted with easy-to-use quick-slide connectors that make installation a cinch. There's no splicing or crimping — just slide one of the Bass Blocker's connectors onto your Crutchfield speaker harness and the other Bass Blocker connector onto your speaker's positive terminal.
Cut-off points are at 4 ohms. If you use 8-ohm speakers, the cut-off point is half the listed frequency.
Note: The .250" spade terminals on these Bass Blockers won't connect to the terminals on some car speakers and many speaker harness adapters (such as Metra speaker adapters). If your speakers or harness adapter use a different terminal, we recommend that you buy a 10-pack of female quick slides to splice on the Bass Blockers.

Product was as expected. Shipping was very fast
Great sound, crisp highs, good value
They were recommended by the Crutchfield guy! Bad idea...they cut the voice range...A waste of my money!
Mine came the wire not soldered to crimps, so it fell off as soon as I touched it. Easy to solder so not a huge issue. The 300 Hz were okay, I ended up using them anyway because the 3 1/2 in sounded better
These are magic. I bought some 600hz bass blockers for some 3 1/2" speakers. Best decision I ever made. It allows you to go further than your stereos crossover/hpf adjustments to make sure that the individual speakers are getting the right frequency. Won't do another small speaker install without these.
Pros: Affordable, Effective, Brings out best in speakers
Put on my tweeters worked great!!
Work as expected, no more low end distortion.
Pros: They actually work.
These work great
Pros: Work great and easy installation
These devices made a great improvement in the performance of the front dash 4" Polk Audio DB402 and rear 4" Pioneer TSG1045R speakers in my 2003 Eurovan Weekender. They completely removed the low end bass distortion from both sets of speakers and the clarity of the high and mid range sound improved dramatically.
I bought these to pair with some Kicker 41KSC354 in the dash of my 88 Monte Carlo SS. Once the bass blockers were added the mids and highs really popped. Previously the speakers would sound a bit muddy on songs with prominent bass, but these stopped that and now the sound is nice and crisp. I highly recommend them!
Pros: Sound quality Ease of install Low cost
Really brought the sound out of my 3.5's.
Pros: Easy install.
Worked great to keep the bass from making my 3.5's rattle and struggle to handle the bass from the deck
Does exactly what's advertised. Filters out unwanted low frequencies from a speaker that can't handle it, creating a cleaner frequency response.
Pros: Filter unwanted low frequencies, inexpensive
Bought the bass blocker to get rid of a lot of bass now it did what i wanted can adjust bass and treble were i like it very good product quick and easy install very fast shipping
My new head unit was driving full range to my tweeters, and it sounded muddled. Now the highs are sharp and bright and it sounds great. They come with terminals attached for an easy installation.
Pros: Easy installation
Did exactly what I needed them to do. Killed the bass distortion at high volume levels, without killing all the bass
Pros: Easy plug and play install
A must have for 3.5" front 2-way speakers
Pros: Easy to install... Makes a huge difference at high volume.
These are a must have to protect your smaller, dash speakers. I used these on the Polk DB351s in my dash. After first installing the speakers without them, I could easily hear the speakers overworking to produce bass, and had to turn them down to prevent damage. After installation of these blockers, I could safely turn up the volume and get excellent midrange and highs out of the speakers. Incredibly easy to install. One for each speaker. Just connect them on your POSTIVE speaker wire, and onto the POSITIVE terminal on your speaker. Done.
Pros: Works well. Noticed an immediate difference in the speaker's performance. Lost the low bass, and allowed the speakers to produce louder, clearer mids and highs.
Cons: None. Worked exactly as needed.
I purchased these so the deepest bass would not blow out my new Polk DXi691 6x9 speakers. I love that they have wires attached. The only problem is that the connectors do not fit the speakers. This is why I gave them only 4 stars. They should come with the right size for new speakers. Crutchfield was out of the right sized connectors so I had to purchase them locally. it was easy to cut them and crimp the new connectors on.
Pros: flexible wires so easy to crimp on connectors. they hold out the deep bass to protect the speakers
Cons: Do not come with the right sized connectors already attached.
Protect your investment! These bass blockers stop just enough lows that you can crank your speakers up higher without all the garble and distortion and risk of cone damage from too much bass.
Pros: Easy to install and small enough to hide in between the factory reverse wire harness and speaker terminal at the speaker locations. Comes with blade ends already installed!
Cons: Had to narrow male blade end with cutters slightly to fit existing wiring. No big deal
After installing a pair of Kicker 41KSC354 in the front dash of my 15' Camry (powered by an Alpine MRV-F300 giving 45W RMS per channel) I noticed they sounded muddy due to the low & mid bass in most of my songs. Once I wired a pair of these 800Hz bass blockers to their "+" terminals, the sound crystal clear w/ no muddy tunes. It's surprising to see just how much of a drastic improvement the sound stage gets but allowing the 3.5" dash speakers to focus solely on the higher frequencies.
Pros: - Easy to wire - Already comes w/ terminal connectors at the wire ends
Cons: - Not getting it sooner
These worked perfectly on my kicker 3 1/2" speakers. I used to have distortion on the lows and now they are working perfectly and punching hard.
Cons: Connectors were too large for my speakers but just cut off the old one and swapped them out no problem, took 2 extra mins total in installation.
Eliminated low range frequencies through my tweeters and in-dash speakers. Installed bass blockers to prevent tweeter flutter and minimize distortion. Easy upgrade to any tweeter!
Pros: Push on connectors ease the job. No worries with overdrivng speaker with bass/low frequencies
Absolutely the solution I needed. I installed 4" Kicker 2 way speakers in my motorcycle fairing and wanted to block the lower frequencies these speakers were never meant to reproduce. They work as advertised. Installation was a breeze, the quality of the product is good, and I felt the price was reasonable when compared to replacing speakers.
Pros: Easily installed and work as promised.
They do exactly what they were meant to do. Quality product. Really helps the little speakers do what they were meant for
Cons: Had to install different connectors
Does their job nicely, nice simple instructions.
Pros: Relatively easy install, no special tools or parts required.
Cons: Had to adjust the female connectors on the Metra adapters that came with my speakers to be large enough to connect to the bass blocker.
Does great job keeping bass from 3 1/2 dash speakers
Just installed these on a set of Kicker 3 1/2" in the dash corner speakers. Definitely can hear the difference with and without them. The speakers would distort because to much bass was getting through. Added the bass blockers, problem solved.
Pros: Does what they're designed to do very well.
Very easy to install - definitely did the job the passive crossover could not because it didn't fit inside the door panel. I haven't had any issue with bleed through and they work well with the JBL tweeters I installed.
Pros: Small, fits in tight space, easy to install, very inexpensive.
Great price and easy to install. Used to save the Mach460 tweeters on my Mustang.
Does the job great.
Pros: Easy install.
The spade lugs on these do not match those on my speakers and wiring harness - they are larger. Because of this, the installation was not as simple as other items I've gotten through Crutchfield. And I have not yet been able to install them because of the need to splice and solder.
Pros: Unable to review because I haven't been able to install them yet.
Cons: Not so easy to install.
These bass blockers work perfect! I've got em on my pioneer 4X6's in the dash of my s10 blazer and the small size fits perfect! My speakers now don't have bass at all so it doesn't distort from bass at all.
Pros: Small size Comes with ends that direct fit certain connectors Work perfectly
Cons: None at all
Great product that worked as described.
Pros: Ease of installation.
I installed these in my front speakers of my 2007 F150.They work great for blocking that low end boom that causes the 6x8 Pioneer the distort.If you are getting a garble sound to your speaker at higher volume then this is what you need.I turns you door speakers into just mid to high range speakers.Leaving your sub to do all the low's. My only gripe is the cost.
Pros: Works as describe.
Cons: Cost to much for what you get. 5 buck would be more reasonable. Electrolytic capacitor are cheap.
Pros: As advertised blocked unwanted freq. stock tweeter was letting in too many lows from new deck but once I put these bad boys in they came back to life.
Cons: A bit larger than expected but I made it work.
Put these in my Jeep TJ when installing a 12" Subwoofer. I upgraded the factory speakers but they are still small 3" and 5" speakers unable to carry any real bass. The Bass Blockers made it easy to cut the low end out of the jeep speakers and run it all through the Sub. I just wanted an inexpensive and easy way to set up the system and this worked great.
Pros: Easy to install and does exactly as advertised.
Cons: I bought the female connectors as recommended but ended up needing male connectors also. Ended up having to run to the store anyway to get the right connections.
The bass blockers worked great. They made my tiny speakers up front sound better without completely eliminating the bass.
Pros: Small, easy to install, work great
Worked exactly as advertised and inexpensive. Did a very good job cleaning up the bass distortion in my 3.5" Kicker CS series dash speakers.
Cons: The spade terminals provided are larger than those found on most spealers so you'll either have to modify them by cutting them a little narrower (as I did) or just replace them with proper sized spades.
Great product. Stopped the popping in the JBL 3.5" Dash speakers I used to replace the factory speakers in a Hyundai Sonata.
Pros: Easy to install.
After installing Kicker 6x9 speakers front and rear I put 3.5 inch Kickers in the dash. The dash speakers over powered the front door speakers. Installing the 600hz bass blockers did the trick. Now the bass is back where it belongs with mids and highs in the dash for a nice sound field.
Pros: Easy install.
I had never heard of bass blockers. I went to Crutchfield with questions about trim plates. They could not help me with that issue however, after a brief description of what I had and what I was trying to do I purchased bass blockers in the 150hz frequency range. I installed these along with a sound ordinance bass amplifier and the combination is perfect. I have to assume these little units are keeping my new 2 way speakers from damage. The speakers sound great and were easy to install in the positive speaker wire.
Pros: Small, easy to install, complete with spade lug style ends.
I had speaker distortion when I played bass heavy music. I spoke with a Crutchfield employee and he told me about bass blockers. He told me to go for the 300 hz because of my speaker size. For the money this is a fantastic option to help eliminate speaker distortion. Thanks Crutchfield!
Pros: Cheap, easy to install, does it's job
I seriously recommend this product
Pros: Its strong and durable
Didn't use as the terminals were not compatible with the wiring harness adapters supplied with the speaker purchase so I don't know if the perform as advertised or not.
Pros: - Don't have any
Cons: - Terminal ends don't work with the wiring harness supplied with the speakers.Crutchfield response on March 24, 2014 Sometimes the spade terminals on these Bass Blockers won't fit your speakers. In these cases, you'll need to clip off the spade and attach the proper-sized quick slides. Our tech support team reached out to the customer to help with this issue.
I'm disappointed with these blockers only because they were recommended for my tweeters but I don't think they cut out enough low frequency.
Pros: Bi directional blockers which is nice.
Cons: Not cutting out enough mids from my tweeters. I guess Crutchfield doesn't carry a blocker that blocks at higher frequencies. Will have to return them.
Work as advertised and simple install
Pros: Saves your tweeters
first off, these are awesome products. i have it on my 3.5" jl coaxials. testing these with sine wave tones, they do not cut off all the frequencies, however, listening to music is another story. they do the job great. highly recommended for anyone with small diameter speakers
Pros: clean mids/highs prevents small speakers from clipping from bass they cannot handle
Cons: sine waves still come through, and cranking near max on music they start to not work as great.
persect to round out my speakers
Didn't know I needed these bass blockers until the Crutchfield tech explained their importance. I appreciate their attention to detail.
Easy to install. They still allow my 6 x 9 to put out some incredible sound. They block out the really low frequencies my 6 x 9 couldn't produce.
Pros: Easy install. Speakers still sound great with these.
No more muddled sound from my dash speakers. They shine.
Pros: inexpensive crossover
I recently installed a stereo in my classic car, but was disappointed to find that if I set the bass level to a good level for the rear 6x9s, the front 6.5s would distort periodically. After the installation of the Bass Blockers (which was very quick and easy), I can set the bass for the rear 6x9s without any of the distorting of the front speakers. Now I can cruise and listen to all of the Motown, blues, and classic rock that I want!
Pros: Work as described. Extremely easy to install. Great price.
Cons: None that I can think of.
Bought these for blocking bass from my small dash speakers. They are working flawlessly. No bass distortion, just nice crisp, clean mids and highs.
Pros: Does what they say they are supposed to do
The blockers look sturdy and super easy to install, I just wish I could've used them. The tweeter connection in a Prius II is apparently hardwired from the connection clip, with no way to use an adaptor or such to attach the blockers. All in all, you can't use them with stock tweeters in a Prius II.
Pros: Sturdy, easy connection
Cons: Doesn't fit every car
What can I say, they block the bass to small speakers.
Cons: One came with two male connectors, not one male, one female.
They work and they are easy
Pros: Easy to instal
They work, plain and simple. They are inexpensive but they do exactly what they say. Amazing!
Get's the job done, I have these installed on two 4x6 speakers and it really cleaned up the sound, no bass distortion equals a happy customer, if amplifying your speakers isn't in your plans these should be!
Pros: Cleans up the sound for a huge reduction in distortion
Cons: Terminal connectors aren't compatible with certain speakers therefore a pack of multiple sized terminals are suggested, only adds a few dollars though
I had never used anything like these before. Figured it was worth a try before deciding whether to spend a bunch of money on an amp or upgraded head unit. Still might do that, but for now my front (new, Polk DB651S) speakers aren't trying to put out bass, making them much clearer. Bass in the 2000 Tundra is a little muddy coming from the rear (same Polk speakers) but I can tell there's bass, which I couldn't before.
They worked great after I added them to my Kicker speakers it cleared the sound up so i could play my music at 11
Pros: Cleared up sound
Cons: The disconnect terminals that came on the Bass Blockers were 1/4" and on my S10 the GM harness and speakers used 3/16" but it was an east fix just annoying.
These were easy to install and help get crisp clear sound out of my speakers.
Pros: Ease of installation
Stopped by the Crutchfield store, but they didn't have them in stock. Went home and ordered them online and had them at my door the next day. I needed them for my Infinity Kappa dash speakers. Being 2 ohm speakers, these bass blockers are effectively 600 Hz blockers, which is what I wanted. They;re of high quality and do the job.
Pros: Good quality; do the job.
Did what it did it would! Speaker's clarity improved a lot!
Pros: It works
Cons: It wasn't free
It's does what it says it does...Great Product A+??
Pros: Reduces 150 Hz
Easy install low levels blocked.
Pros: Easy to install
Bass blockers were easy to install simple and to the point very clear instructions with great care and protection in the shipping a great addition to my sound system i can nkw turn the volume up without the distortion and feeling like my doors speakers are gonna blow thanks alot and highly recomended
Pros: Protect ur speakers and get much clearer sound at higher volume
Cons: None in my opinion simple great diference in sound no worries unless u dnt like taking the time to take ur door panel apart but simple job
These work perfect with no problems.
Pros: Keeps the speakers from distorting at high volume levels.
Not much to say here, but they do what they have to do.
I used these on high end Focal speakers, sound great, protect well. They roll off nicely and although I don't have a sub yet, i can still listen to and enjoy my full range speakers.
Easy to hook up, works like a charm.
they seem to do its job. It keeps the bass distortion to zero at high volumes.
Pros: The spade connectors makes it easy to plug right in.
Cons: Wished the connectors had insulation on them. Used electrical tape to make sure it does not inadverdently grounds out.
These went on the front 4 inch Polk speakers on my 99 Jeep Wrangler. The connectors didn't fit exactly on the speaker harness. They were too small to fit. had to cut off one connector and crimp another one on. Other than that, straight forward install.
Pros: Appear to work.
Cons: Original connector didn't fit on speakers.
I used this with a set of Focal Polyglass speakers in a Scion IQ. It was pain to install because the male connector would not fit into the wire harness provided by Crutchfield. It is just a little too big. I remember doing a similar install years ago and i ran into the same problem. I ended up having to splice the wires together. The end result is amazing. It definitely allowed my speakers to shine with its mids and highs. I would have given it 5 stars if i didn't have to alter the wires.
Pros: It works as expected
Cons: Does not fit on the provided wire harness. Alteration is necessary.
Just got these in today and I must say they are amazing! For being a cheap passive crossover solution, these really help those who want more out of their aftermarket speakers complimented with a subwoofer system. I was able to turn up the bass setting higher to send more bass to the sub whilst keeping harmful bass frequencies from my speakers. The 150 hz cut-off is perfect because a good amount of bass the speaker can handle at loud volumes are still being played through the full range speakers. Now I can really turn the volume up without distortion from unproper bass being fed to the full range speakers. The difference is almost unreal. Hard to explain in words, but "Music Heaven" has been reached in my car. :P Highly recommend these for anyone with a subwoofer system in their car, or anyone with aftermarket speakers, or a combination of both.
Pros: Cheap, Makes a world of a better audio difference, Lets full-range speakers handle frequencies they can handle at louder volumes for cleaner, crisper, distortion free(in some cases), rich sound. Easy to install.
Cons: Male slide terminal didnt fit my current female terminal, but not a problem since splicing a wire is very easy.
My Pioneer Deck didn't have the High Pass Filter feature, so I bought 2 pairs of these bad boys. They eliminated the low frequency on the front and rear speakers which is exactly what I wanted. I let my Sub take care of the Low Frequencies while the main speakers bring out the Mids and Highs with no distortion. Sounds really clean now.
Pros: Easy Install and they work very well.
2006 Ram 1500 Quad Cab upgrade. Installed 3.5 Rockfords in the dash along with recommended 600hz lockers. Incredible! They do what the say. Will be making another purchase of 300hz for my 5.25 Rockfords. WOULD RECOMMEND to any and every one wanting some simple protection and sound enhancement. NOTE: modification may be needed to fit some applications. If this is too difficult or unacceptable, you need not buy or complain. SUCK IT UP!
Pros: Simple... Enough said.
The quick connect sliders are the WRONG size for speakers connections. Crutchfield, WHY even sell these if they don't fit the speakers?
Cons: They don't fit.Crutchfield response on May 14, 2012 We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.
I was adding a powered subwoofer to my system so I didn't need low bass at my other speakers. These are easy to install and I guess they do their job. My system sounds great.
Plug and play (04 mustang) unlike previous reviews. Would recommend this product to anyone.
Pros: This product performed well above my expectations. These Bass Blockers allowed me to keep my factory tweeters while powering with the HU only, no amp. Exactly what I wanted them to do! Crystal clear sound.
Cons: No cons, this product simply works!
I have 51/4 speakers on rear deck, my pioneer is over driving them. I install this product problem solved
I have a Ford Explorer with NAV and Video from the factory so I want to keep my head unit and I'm not in the frame of mind to install an amp. at the moment, so the base blockers worked magic on my front Boston Acoustic 5-1/4 components. The head unit has limited bass control and it was not filtering out low bass and even the Boston's can only handle so much before sounding like total s*#@. I tried the 300HZ as indicated but it took to much bass out so i landed with the 150HZ. They sound great, clear upper and midrange with to proper amount of lows. Two complaints: 1. The quick connectors are too wide (they don't fit) and you need to modify 2. The base blockers don't have any marking on them so if you get two types don't mix them up as it's hard to tell the difference. Yeah the wire color different but if you forget what was what you need to perform a sound check to figure it out.
Once installed they work fine, but getting them in was a process even though it should be simple. 1st, as others mentioned the terminals don't fit a lot of speakers. In our vehicle we have 3 sets of speakers all different brands and the terminals didn't fit any so all had to be modified. 2nd, the solder joint between the wire and the component can be weak. On 1 of them i was installing both sides popped of as i flexed the wires to install the speaker so I had to take it out and re-solder.
They do just what they say. Only issue is the spade terminals are to large for todays speakers. Not a big problem, just cut em off and splice them into your pos speaker wire.
These definitely do their job and work as described, however, I didnt care for them. I used them on Infinity Kappa series 682.9cf 6x8's and ended up taking them off after 2 days. So even though they work, I cant give them 5 stars because I didnt like the result. I felt the 300hz cutoff was too high for those particular speakers.
Speaker terminal too large for Boston Acoustics postive speaker terminal. You have to splice in the terminal that comes with the speakers.
This product is awesome for someone looking to get better highs from your smaller speakers without having to spend the money for an amp. I have these installed in my dash and sound bar speakers in my Jeep Wrangler. I didn't know how they would work at first, but I must say that this has been the BEST $10 I have spent on sound equipment. They take out the bass to give you crystal clear results and let the subwoofer do all the heavy hitting with the bass. I highly recommend these Bass Blockers to anyone that wants to let your radio push your smaller speakers!!!
I bought these by advise from your advisor. I had never used bass blockers before and they made my new speakers sound great/
Too difficult to setup with the harnes for Honda Acura aftermarket speakers (don't fit)
These are a very effective and affordable passive crossover method. They basically convert your full range speaker to Mid - High range sound output. This prevents smaller speakers from distorting or squashing out when trying to re-create big bass at higher volume. The only draw back is they are not flexable as far as what cut -off feequency they pass so choose your cut off frequency carefully. If your not certain which is best for your aplication, the general selection guide on the web site is probably your best bet.
great item, suprised that they cut only enough bass to keep the speakers from fuzzing (is that a word). Glad the salesperson advised these.
These bass blockers are probably the best investment Ive made for my audio system. I was very, very suprised when I heard the quality of sound that came from installing this product. It took me a total of 10 minutes to install these Bass Blockers, too! Now all my lows go to my subwoofers and my 6x9's do the rest. These worked so well that im thinking about purchasing another pair for my door speakers.
These bass blockers worked just as all the previous reviews about them said they would. For the extra money with my Kenwood Speakers, it was definitely worth the investment. Installation is easy with these. I was able to turn the volume up a good amount louder without the bass starting to sound bad. These are supposed to help the speakers to last longer also which is another bonus feature about them. I would definitely recommend these to anyone looking into buying a set of good speakers.
This is a great product. A small price to pay for great sound. I can now turn the music up much louder than before without any distortion. I recommend this product to anyone looking to improve the overall sound of their system.
worked great now i can turn up my radio with out any disortion would recomend to anyone that wants great sound.
I HAVE A 2005 DODGE RAM 1500 QUAD CAB. I HAVE A PAIR OF 3 1/2" INFINITY SPEAKERS IN MY DASH. BEFORE I INSTALLED THESE, EVERY TIME I TURNED UP THE MUSIC TO CERTAIN LEVELS THEY WOULD POP AND DISTORT. NOW AFTER I INSTALLED THESE MY SOUND IS CRYSTAL CLEAR AT ANY LEVEL AND I RECEIVED AN ADDED BONUS. NO DISTORTION. THIS IS A SMALL PRICE TO PAY FOR THE BENEFITS YOU RECEIVE.
I installed 600Hz blockers on my 3.5" Boston Acoustic dashboard speakers. At low volumes, the 3.5" speakers didn't make any bass anyway so they aren't that noticeable. But at higher volumes, you can notice that all your bass is coming from behind you. The speakers get VERY loud and don't distort when they aren't trying to produce low frequencies. I highly recommend blockers for smaller speaker sizes. You won't have to worry about blowing your speakers when you're driving with your windows down on a highway anymore!
if you're buying tweeters and/or midrange speakers BUY BASS BLOCKERS! this will ensure speaker performance without minimizing lifespan. for an extra few bucks, it's worth protecting a $150 investment
I purchased these for my 05 mustang. I had replaced the factory speakers in the doors and back deck with pioneers. The base was pretty heavy. I bought two of the 150 mhz base blockers and added them to my door speakers and wow what a difference. The door speakers are much clearer now and i can hear the distinct sound difference. I left the rear deck speakers alone. So with the two 10" subs in the doors plus the back deck speakers i still get all the clear base i want but now will clearer crisper mids and high tones from the base blocked door speakers. The difference was night and day.
I have a reg. cab Silverado with an Alpine 9886, 2 infinity 6.5's in the doors & 2 infinity 4x6's in the panels behind your head. Too much bass was getting to my 4x6's and I was scared to blow my new speakers. Saw these 600Hz, and had to pick them up. They worked perfectly & were easy to install in line with the speakers. Sound is crisp & clear w/out any distortion! Now I can bump my music loud without worying. Definately installing them on the 6.5's ASAP when I install my 12"!!
I bought the 600 Hz version when I replaced the oem speakers in my car. I run a low power system with a basic Kenwood receiver. When I installed these, I noticed a substantial decrease in the volume of the front speakers, which I fixed just by balancing the sound more to the front of the car. The quality of sound did not improve at all, but I left the set up just for the sake of protecting my new speakers from too much bass. A short time later I noticed that my front speakers were not making any sound at all. I found that the bass blocker had fried itself. The connection basically melted away. Now my speakers work fine and sound much better just by removing the bass blocker.
These bass blockers are well worth the money. After I installed these, my speakers were a lot louder, and the crisp notes were more noticeable. I would recommend these to everyone even if they don't have a subwoofer. Since most 6 1/2 speakers do not produce bass anyways, why not block it out? If you purchase these bass blockers you will not be disappointed.
They do exactly what they are meant to do. I am very pleased.
After installing the Bass Blockers on my front side door speakers, the bass coming from my rear 6x9s was much more noticeable. In addition the front speakers sound much more clear and crisp without the lows being pushed through them. The Bass Blockers made a big improvement in the quality of the sound coming from my car. This was money well spent!
Even if you are just powering with a head unit these will make a difference. They filter out low bass, therefore drastically cutting distortion to speakers not meant to carry heavy bass. The bass in my car comes from my rear 6x9's. Mids and highs should come from the front since it's easier for the ear to locate mids and highs. I am now able to fade my system to the front, ensuring mids and highs come through *without* the bass that would normally distort them. A great buy, I highly recommend them!
Bass Blockers sure cleared up the distortion I had in my my speakers and brought out the mid bass and highs out of my new Infinity speakers. With the addition of Bass blockers my Bazooka tube really stands out. Thanks Skip and Crutchfield.
I'm currently using two pairs of these: 150's and 600's. At first I was skeptical on actually needing these. Putting them in made all the difference. I've been installing systems for several years now as a hobbyist, and these blockers push the cleanest, most efficient sound I've ever heard through my after-market speakers. If you have a small car and subs in the trunk... GET THESE. You'll finally have something to rival the rattle. It's completely worth it to tack these on when you're buying replacements. I put these in after already having installed my speakers, so it was a bit of a pain to get to everything again, but it was definitely worth it. No question. Just be sure your head unit isn't trying to push more than 50w/ch.
THIS BASS BLOCKERS ARE THE BEST
You must get these for your speakers! The results are amazing. Clean Clear Highs, with NO bass distortion!
I used these cuz I kept blowing my speakers in my car. I have subwoofers and didn't want my speakers bassing too much so I saw these. They made the difference. Now I can turn it up loud and not have to worry about my speakers blowing. Everybody needs these if you have some bump in the trunk.
I have a GMC full size pickup with Boston Acoustic 6x9's and a subwoofer in the back and 4x6's in the dash. The front speakers were breaking up even at moderate volumes. I tried the 600 Hz base blockers per Crutchfield's website recommendation. They made a huge difference. I can now crank it up without a problem.
I'm using 600 Hz Bass Blockers on my Polk db460 4x6" speakers in the dash of my 99 S-10. They sound great, with no distortion. I highly recommend them.
I have a truck (86 F150) with a high power (50x4) head unit, 2 6.5 door speaker and a custom 2x10 enclosure with it's own amp that just didn't sound right. The door speakers kept breaking up. I added these 150hz bass blockers and it totally transformed the sound. If you're using your head unit to drive speakers and you have a sub I would get these in an instant. It will really clean up your sound. Only complaint is that I would want them at about 100hz not 150hz. My Subs aren't good for much over 130hz so there's a tiny hole, but not real bad.
My Home Theater system had a bad distortion problem.So,your salesman said that I may want to install a 800Hz bass blockers on the 2 1/4" speakers & 600Hz on my 5 1 /4" speakers.The sound now is PERFECT! Thanks for info.!
Overview: Bass Blockers stop speaker distortion caused by excessive bass relative to a speaker's bass output capability. They are especially useful with small diameter speakers and tweeters. Bass Blockers are typically installed right before the positive speaker input terminal, in-line with the positive speaker lead.
Easy Installation: To install a Bass Blocker, slip the female connector of the bass blocker onto the positive speaker terminal, and plug the male connector into the speaker lead. If you don't want to use the terminals, cut them off, cut the speaker lead at a convenient location close to the speaker, then splice the Bass Blocker into the positive speaker lead and insulate the connections. Bass blockers are not directional, so the orientation of the Bass Blockers on the positive speaker leads is not important.
Note: The .250" spade terminals on these Bass Blockers won't connect to the terminals on some car speakers and many speaker harness adapters (such as Metra speaker adapters). If your speakers or harness adapter use a different terminal, we recommend that you buy a 10-pack of female quick slides to splice on the Bass Blockers.
Slope: The roll off rate is 6dB/octave, and the frequency each bass blocker is rated for (i.e. 150, 300, 600, 800Hz, etc.) is the point where response has been lowered by 3dB.
|Model||2 ohms||4 ohms||8 ohms||Wire Color|
Power Handling: Each Bass Blocker is capable of handling up to 50 watts RMS.

My rear doors only support a 4" speaker which is not really capable of full-range sound, and these will help to protect the rears from frequencies they just can't safely produce at moderate volumes. [ DANIEL J May 29, 2016 ]
This is a simple and inexpensive way to stop sending extremely low frequencies to relatively weak factory speakers. Now that I am installing a powered subwoofer, I didn't want to dial out the low end on the head unit to avoid distorting the door speakers. This way the sub will get the full range of input and fill that void. I wasn't sure which cut-off to use but I expect that 150 Hz (the lowest available) will be better than nothing at all.

Thought it made good sense to block lower frequencies from 3.5" speakers I was replacing in the dash. [ Lee Apr 22, 2016 ]
These are to be installed inline with 3-1/2" two-way speakers. The 300Hz threshold on these blockers will keep the frequencies at the speakers well above their 90Hz floor and out of their low-end roll-off curve. This all means the speakers should be free of any mechanical distortion at any sane power setting. [ KEITH Apr 20, 2016 ]

I used Chat to get a few technical answers and discuss options with a Crutchfield expert. He helped me narrow down the speakers I chose and then suggested I consider Base Blockers for the front speakers to help prevent distortion. As they were only $10 it was a no brainer. The tech had recommended 300Hz for my particular speaker even though the site said 600 hz for that size speaker in general. He said my speaker could handle the lower rating so 300 would serve me well. Thanks Crutchfield! [ David Jan 06, 2016 ]

If you have a sub they work well helping to prevent you smaller speakers from trying to produce lower frequency's they are not capable of producing which in turn helps prevent them from blowing. [ Tammy Nov 04, 2016 ]

Yes, however, they've been reviewed to have great low frequency response. Even though they should be large enough to perform well with a 150 Hz cap, I'd go with the 300 Hz instead. Let the subs take care of the bass. [ Nicholas Apr 07, 2016 ]
This will depend largely on your vehicle and your set up. For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation. [ Kenny Mar 25, 2016 ] Staff
I forwarded your question to an Advisor and they responded with the following: The components should be using a crossover which will eliminate the highs from the tweeters. We don't carry any bass blockers for the 6x9's. Usually the frequency range on that size speaker can accomodate plenty of bass and does not need a blocker. So you do not need bass blockers for either location. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy May 12, 2015 ] Staff

go with 1200/1500for tweeters and 500/800 for mids [ Thomas Jun 24, 2016 ]
the 800s will do fine but if you have a hi pass crossover built in your amp or radio use it to as well [ THEODORE Jun 28, 2014 ]
The 800hz blockers will work fine. I don't know about the Kickers, but check before you buy the blockers because some smaller diameter speakers come with blockers already installed at the factory so buying another set isn't required. [ JOHN Jun 23, 2014 ]
I used the 800hz and they sound good but honestly, if you're using an aftermarket head unit then you can probably get away with the 600. Just a thought. [ OCTAVIO Jun 23, 2014 ]
yes [ Thomas Jun 24, 2016 ]
They will work fine, just be sure that they don't already come with bass blockers (some speakers do). Also, if you're using a crossover network, bass blockers aren't necessary, because the crossover handles that chore. [ JOHN Apr 19, 2014 ]

1200/1500 hz cut off for tweets 500/800 for mids [ Thomas Jun 24, 2016 ]
I used them on my tweeters and they work well. I have no amps or anything simply the head unit and I get a great sound. [ JOEL Dec 30, 2013 ]
Bass blockers are used to prevent the lowest frequencies from going thru tweeters. Because tweeters reproduce the high-end sounds in the frequency spectrum, trying to get them to reproduce bass level sounds could damage them and the sound will be distorted. I think you are confusing the equalization curves in your deck with a cross over network which must be installed in the speaker line from a separate amp. (You don;t say whether you're using a separate amp or not). Frequencies above 800hz are still considered "mids" so the bass blockers won;t stop the tweeters from receiving those frequencies but they will prevent distortion and damage to the tweeters. If you are using component speakers (woofers, mid range and tweeters and again, you didn't say), they should have a cross over network installed which should correctly separate the frequencies to match the capabilities of that particular brand of speaker so the bass blockers wouldn't be necessary. [ JOHN Dec 22, 2013 ]
