1" silk/polymer dome tweeters
Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.
Polk's db691 speakers feature 6"x9" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 1" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. The 3/4" dome supertweeters add even more sparkle to reproduce your music's natural intricacies. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.
These db Series speakers feature stainless steel mounting hardware and muscular ABS grilles that will add a stylish touch to your car's interior.

Average Customer Review(s):
Great sound and a awesome value.
More bass than I expected. I had to turn mine below flat.(not complaining) For the first time in my life, and i'm 67 years old, I could hear the differences between the high hat, snare drum and cymbals in a car. The separation of instruments is fantastic! No muddy bass guitar running into the bass drum or tom-tom. Super clean, crisp brass and winds.Timpani instead of distant thunder. A piano that sounds like I'm back at Carnegie hall. I'm hearing sounds on recordings I've listened to scores of times and still can't believe it.(Ringo hitting a cow bell on Magical Mystery Tour?) You lose ability to hear higher ends of the spectrum with age,thanks Polk Audio for giving my ears new life. And to Eddy at Crutchfield for the recommendation.
Pros: Unbelievable instrument separation. Bass notes are distinct
Cons: Con and Polk db691 do not belong in the same sentence.
Easy install, fit great and an awesome upgrade. They sound great.
Awesome speakers. Excellent for the amount of sound I needed where it was needed behind me on my motorcycle. They sound great.
Pros: Marine grade certified.
Cons: Had to adjust mounting holes to fit.
Great sound, fit perfectly.
Sound is good, bass is a bit week, but I'm guessing it if I had an aftermarket amp these would liven up..
Pros: Good highs and mids
Cons: A bit weak on bass..
First Polks speakers and they deliver nice bass, great mid and crisp clear high tones. I can compare with my high end home speakers on clear sound.
Pros: Really nice sound at a great price, you can't go wrong with this pair.
Great Speakers- Screaming highs with Awesome sound at a Perfect price
Pros: Nice Highs and Lows- No distortion
Cons: Make sure your door panels won't interfere with protruding Tweets. It pushes mine outward but doesn't affect performance
The original rear deck speakers in my '91 Cadillac needed replacing, after much research on Crutchfield.com I got the db691s. They are awesome, the highs are great and the bass is superb. Now I want the 5 1/4 Inch dBs for the front doors! I have Polk Audio products in my home and they are perfect for the price.
Pros: Easy Installation. The wire harness was simple to use.
Fantastic speaker with top notch Polk quality. Plenty of bass, very solid, and not boomy. There's no sacrifice any mid-range or highs either. These are clean, crisp, and clear. Running them with a 150 watt RMS amp and handles the power flawlessly without any hint of distortion. These speakers are more than just a "factory upgrade". You won't be disappointed if you make these your choice.
Pros: Quality construction, fantastic sound.
Speakers sound awesome but did not fit as promised. Had to move mounting screw holes because they did not line up
Pros: Soiund Awesome
Cons: Had to modify to fit
Love Polk never had problem from car to house to outdoor soeakers. Love em
Pros: Sound Amazing
Cons: Wish I had more
Very good, as promised.
These speakers are awesome. There loud as can be and still sound clear.
The best speakers money can buy.
Got these for my work van along with a Pioneer media receiver and 6.5" Polk components. Made an awsume addition to my work ride without even having a sub or amp. Already knew these were great. I have a pair in the front doors of my 07 Tundra. They are especially good with an after market head unit.
Pros: Amazing how good these sound even though I have them in small Sound Ordinance boxes behind the seats between the safety cage and seats. They still give some highs and mids from behind to give that nice 4 speaker sound. And man do they give a nice bit of extra lows for not having an amp. Always a fan of Polk speakers house or auto, so not really a surprise for me.
Cons: Nope, none. Well except I can't afford to just change everything to Polk in the house also .
Upgraded my speakers on my 06 Roadliner, the sound is considerably better. You won't be disappointed with these speakers.
Pros: Clear and recognizable audio at highway speeds.
Cons: Silver grills.
GREAT Sound w/out distortion. This is currently the 4th pair I've bought with ZERO complaints. with more planned. However this is currently the only pr i have hooked up to an amp (JL audio 360/2 amp). Great Volume, sound quality. Would recommend to anyone for any application. I have them in my Toyhauler (used as outdoor speakers), this truck and other trucks ('75 Chevy C10 and '66 Chevy C10). All are mounted in "generic" angled truck speaker boxes.
Pros: TOP NOTCH QUALITY
Cons: Haven't found any yet
My wife and I are very satisfied with these Polk's. I installed them in our camper, up in the overhead storage compartment, as if they were ceiling ,mounted. Man do they rock our camper, and can get up pretty loud before any distortion takes place. With a bit more power, I bet they would really preform outstanding.
Pros: low cost, sound really great, for marine envoirments
I put the polks 691DB in my 68 Firebird they sound great . I have a old school amp 240 punch by 4 my deck puts out 15 by 4 that's 75 watts per speaker. Still have 6 1/2 round Eclipse in the front doors .they sound great.
Pros: They sound great from low to vary high as much as my ears will take !
The speakers sound good, installation was simple. Installed them in my 84 Vette, installation was not good. the tweeters protrude above the mounting flance, which required modification, a spacer under the orignal grill. The grill provided with the speakes offered little protection and were ugly The sales person did not provide any info about the installation.
Pros: sound good
Cons: ugly grills provided, installation was a pain
Installed Pioneer MRP-300 amp and Polk 6x9 's and they sound worst than the Pioneer component speaker with the alpine in dash deck powering them . Total disappointment ! Door were sealed tight as a drum , hooked the amp up to the pre-amp outputs , used the amp power supply that was recommended by Crutchfield . And It sound awful . I don't know if its the amp or the speaker but what a waste of time and money
Cons: Stuck with a well below average system that I paid for with hard earned money
These were a disappointment. I bought them on sale to replace some super cheap kicker 6x9's. I'll be putting the Kickers back in. Save yourself the money and buy the cheapest kicker 6x9s if you want this level of quality.
Pros: They look pretty
Cons: Polk audio has join the rest of American producers in degraded quality posing as expensive equipment. You got me again!
I bought this Polk 6x9 and install them in a box and put them in the back of my truck and hooked them up to a amp very happy with the sound
Pros: Great price
Used these in the rear deck! Love the crisp clean sound. Polk Audio has been around a long time and has always been towards the top as far as quality. My Home Theater is all Polk Audio. This and the reviews are why I chose these. I have a Pioneer HU with built in power and haven't even hooked my amp up yet and these sound amazing! I would highly recommend these you won't regret it!
Pros: Clear crisp sound with just enough low end to not sound boomy. These replaced my speakers in my 2007 Saturn Aura and have made a huge difference. Easy to install.
This is our second set of these speakers. We put these in our new pontoon boat (the old set was in our old pontoon). Great sounds quality!
Pros: Great sound quality
Good well built speakers really bring the music to life. Great sturdy construction should provide years of listening enjoyment, even with my fits of metal core and screamo. These speakers make country music sound live.
Pros: Great sound, well built, multi attachment bracket included is a plus
Cons: None as of yet
Great sounding speaker, high quality construction. And the fit guide says they won't fit They do with a very minor modification made with a utility knife to the plastic port tube behind the oem speaker. Have to thank Dallas for pointing me to these and looking up the specs on my car and letting me know what to do to make them fit. REAL customer service!! Always shop here for car audio! These people go above and beyond!!
Pros: POLK name! Build quality! Unbelievable sound at this price! Great value with Polk Audio!
Cons: Grilles are a little too obtrusive for me but could not use anyway. Better grille options would be nice!
I put the Polk DB691 in the back of my 07 Honda accord ( Crutchfield says they don't fit but they do) and Polk DB 651 in the front. I only replaced the speakers and no other equipment. These seem to be working really well with my system (180w) due to the high sensitivity rating. I know that the would work even better with a head unit / amp. Overall, I think these speakers are an excellent replacement for an otherwise stock system.
Pros: Works excellently with a stock set up. Great improvement on overall sound with little investment. Great highs and mids.
Cons: Bass is fine for now but will give up if i try to crank it higher. I imagine this problem would be fixed with an amp.
Great speakers! Installed on a custom built Bagger motorcycle and you can hear them CRYSTAL CLEAR on the highway over the loud exhaust with just a JVC head unit!
Pros: Awesome sound, good looking griles, allows for expanding system!
Cons: No real cons, except since they can handle so much power they beg for you to expand you stereo!
I put these speakers in boxes and hooked them up to an alpine deck with no amp, all they did was screech. So I put them in a jeep with an amp pushing them, absolutely no better/ worse. No bass, can't hear much of the guitar or midrange just horrible. The old Kickers 6x9 and some old Fosgate R series 6x9's were better.
Cons: about $100 overpriced
I bought these for a project car and did tons of research, I wanted a good sounding 6x9 in the $75 to $150 range. I really wanted a good speaker that would rock out and most reviews were good and no shortage of reviews on this speaker. Wow, I returned them as fast as I could, they were horrible, a tweeter is what they are, you can't here the bass the band (you know the music) nothing sounded good. So I paid extra and got the JL c2 6x9, man they are 100 times better.
Cons: screechy with no bass once so ever.
Excellent addition to my 2011 Tundra DC! Needed to make some adjustments to the front doors (cutting existing speaker grills, and used adjusted existing speakers) and now fit nicely. I have them hooked up to an amp and these get loud! They complement the other 3.5 DB's I have in the dash as well as the 6.5 DB's in the rear doors. I started with these un-amplified, but they SHOULD be amplified! Great and Crutchfield supplies exactly what you need to make it an easy install!
Pros: Looks, functionality, sound and BASS!!
Cons: None except I had to make adjustments to my Tundras doors to fit them.
I fit these in my 2004 Dodge Ram. Yes, they do fit fine with just the included spacer. They have clean and crisp highs, mids, and surprisingly good lows. They rattle my rear view mirror at only 35 volume level, and I am only powering them with a basic Pioneer single din head unit that is 14 watts RMS x4. So I am not even pushing them anywhere near their 125watt RMS rating. I cannot attest to durability as I have only had them a few days, however past experiences with Polk products encourages me to think these will hold up for a long time. I paired them with Polk db651s 6.5" speakers in the rear doors. Eventually I will be putting an Alpine Type R 12" under the back seat to compete the sound system. Can't go wrong with Polk speakers!
Got these on sale and it was honestly some of the best money I've ever spent. They are amazing speakers. The sound is great. Fantastic highs and midrange and good bass especially from 6x9s. I've had them for about a month now and so far I have no complaints at all. Easy to install with the harnesses they supply you with
Installed these in the rear deck of my 2011 Ford Fusion which was a stretch because it didn't come with factory 6X9's there so had to do some cutting etc. but it was so worth it! These speakers handle the full spectrum of sound with such incredible clarity and ease and sound really great matched with my Pioneer deck and Alpine power pack amp. I've had several Polk speakers over the years and have always been impressed with their smooth sound and excellent build quality.
Pros: Smooth sound, very detailed, excellent quality
These speakers sound great off my Kenwood head unit. The lows sound decent, but the mids and highs have really improved dramatically over the stock Toyota speakers.
Pros: Great mids and highs.
Cons: Although there is a high sensitivity rating and low frequency response, the bass is not all that loud. I can imagine that if there was an amp hooked up to them, the low end would sound great also.
I purchased these speakers about a month ago, and there nice, the sound is a little less loud but the amount of clarity makes up for it, i'm running it off my stock HU, so they can and will get louder when ever I want to invest farther into my radio, but crystal clear, not bad price, easy install. compared to my speakers in the the truck (stock) when i put them out... really didn't think they would fit. bass kind of picks up too.
Cons: loss of loudness
Great mids and highs. I'm hoping that hooking up an amp will help the bass.
Pros: Great crisp sound
Cons: Bass is a little lacking
I purchased these 6x9 Polks to replace factory speakers in my 08 Dodge Ram. The fit was perfect and went very smooth. The overall sound quality is great with my Kenwood HU. The bass is respectable, but I added a powered sub to this install anyway.
Pros: Sound quality, fit, price
Have great range from tweeter to mid-range. Obviously need a sub to complete the full spectrum. Being pushed by 4 channel amp and handles the power well.
Great value and crisp mids and highs
Pros: Price & sound quality
Cons: Not much bass
nice speakers fast shipping , easy install , sound great.
Pros: the wire harness made install easy ,and the difference in sound compared to stock speakers is night and day. thanks
Cons: the directions that i received to remove the door panel were wrong , you lift the door panel up to remove, you do not pull it out or you will break the the panel itself.
I'm a polk fan for life. These speakers make a world of difference.
Pros: They fit perfectly.
sound great with a small amp
Installed these in my 05 Dodge Ram's front doors today, connected to an Alpine CDE-HD138BT. They have a very, very clear and clean sound. They get very loud even running on just my HU's power. I'm not getting a ton of bass, but they're brand new and aren't being given a ton of power, so that could be part of the issue. I imagine more wattage would help, but honestly i can't imagine how loud the rest of the audio spectrum would be with 100 watts being sent to them. It would be seriously deafening! In any case, these combined with DB351's in the dash make for sound that is tremendously cleaner and clearer than my stock "Infinity" system. As an aside, Crutchfield says these don't fit in an 05 Dodge Ram and I have no idea why. They fit easily and with room to spare, both in front of and behind the speaker. You just have to reuse the stock speakers' mounting spacers. Crutchfield really should add these to the speakers that show up for an 05 Dodge Ram under "outfit my car".
Pros: Very sensitive. Clear and accurate sound. Fit well in an 05 Dodge Ram front doors.
Cons: Not a lot of bass in my application, but that could be due to them not being broken in and not receiving a lot of power from my HU (18 watts per channel RMS).
I was in the market for speakers to replace my factory wackness, and I was chating to one of the company rep's on line. they recommended the Polk db series. what a difference. finally great speakers. it was a great move.
love the way they fit in the rear deck of my my 2012 altima sr sedan
Pros: taking the car apart was harder than putting the speakers in !!!
Cons: no wire clips for wire connections
nothing but "POLK" quality
I actually had to wait for a few months to buy these because Crutchfield was out of stock. Totally worth the wait. They sound pretty close to perfect. I listen to all types of music, from hiphop and electronic stuff to folk and rock. Clear mids and highs and a nice little oomph of bass. Installed them in like 25 minutes into my honda civic hatch. If you're into like crazy boomy bass then you will definitely need an amp and sub, but these bang on if you're into clear and precise sounding music. For the price, this is a great product. I'm a new fan of Polk. I also have to say that Crutchfield seriously rocks. I ordered on a Sunday and they arrived Tuesday morning, free shipping was awesome. The guys from Crutchfield called me (because I typed in my address wrong) and were super nice and accommodating on the phone. Crutchfield is the best, don't bother ordering from anyone else.
Pros: Easy to install, great mids, really clean bass, an awesome upgrade for your system.
It's funny how you never notice how bad stock speakers are until you change them. These speakers are crystal clear and you hear your music like never before. I have used Polk before and they have never let me down.
Replaced (4) factory speakers- These 6x9's up front sound better, especially at HIGH volume, than all 4 of the stock speakers. Even impressed with the bass and mid response. Installation was simple and smooth, all the adapters were perfect, instructions spot on and easy to follow. I did forget to secure the wiring adapter, which adds about 6" of wire inside the door, so my window rubbed it on the way down. Easy fix and I was warned ahead of time, just forgot.
Pros: Crisp and clear at high volume- mostly listen to metal. FFDP, Sevenfold, Metallica, etc. I used to stop volume increase at point of distortion, now I stop because it's too loud. VERY happy with bass.
Cons: Little worried about the tweeter, which pushes slightly on the factory door grille. Too soon to tell if it will cause damage.
I bought these speakers for my Honda to replace a set of Kickers I had installed years back. In the first week they were installed they didn't impress me too much but after a couple weeks of break-in they have some great sound and even add a bit of bass (I don't have a sub currently). I have them paired with a 300W Rockford Fosgate 4 channel amp and have a Polk Component System in the front on the same amp. With this setup the sound is crisp, clear and loud.
I bought these speakers for my boat because they are marine rated, sound great in my boat.
After reading the other reviews on your site, I felt like I was taking a chance when I bought these, but I love these speakers! I have them in the front door panels of my pickup, pushed by a Bazooka amp, and they produce the clearest, deepest sound I've gotten from many sets of speakers I've bought over the years. They have enough low end on the hip-hop stuff to rattle the doors and yet produce some really piercing highs listening to rock and the occassional diva track, but they really shine when they get to show how effortlessly they can do both at once on more complex jazz and country pieces. I couldn't be happier! Kudos to Polk for a fine product
Very good product. When I called I asked what was best for what I have and Buck recommended these and they sound great. Got everything to install them. Shipping was super fast and service was super awesome
Great sound, solid base, good clarity and image in the higher frequencies. I am powering these with a RockFord fosgate 100W amp, so that doesn't hurt my impression. Have them mounted on the rear deck with the 4" 2 ways in the front doors. I'm very satisfied and would purchase them again.
These speakers are something else! I purchased these after being VERY disappointed with "kickers " that some reps sugested were great ( I returned those) These speakers have lots of CLEAN bass and blend in well with the highs and mids from my front components. I have them hooked to a Rockford Fosgate amp, however I have to keep the gain below half. I believe these things would push lots of bass from any deck with or without an amp. The Kickers I tried were way too high on the highs and distorted on lows even at moderate volume. When you call, I recomend KEVIN at EXT 4043 as a good rep.
Amazing sound out of these speakers. I was concerned about the sound I was going to get after reading a number of reviews about needing an amp to power them. I have this hooked up to my stock deck in a 2006 Dodge Ram. I added the Polk Audio DB651s for the rear speakers, but honestly they are not needed. The highs and the lows that come out of these 6x9's is very impressive. The fact that they have a built in crossover is nice, the bass comes through very clean leaving the highs loud and crisp.
I read a bunch of reviews for these speakers, and found a lot of people saying no sound comes out of these, my stock speakers worked better than these, or something along those lines. Before I buy a speaker I always check out the the specifications and one thing I noticed about these was was their minimum power started at 10Wrms. Thats a very high starting point for speakers! I realized with this that meant even the best head units out there were only going to push out 14-18Wrms which means your barely going to be pushing these bad boys. Would you settle for a nightlight in every room of your house as all the light you had? Anyways I hooked the speakers up to Rockford Fosgate Punch P400.2 and WOW, what an amazing difference! They went from cranking the H.U. up just to hear them to turning them up halfway and now shaking my mirrors. Take it from me these are good speakers, you just have to get an amplifier.
I have the Polk db 691 and db 651 coaxials driven by a Kicker Zx350.4 (60w x 4 ) amp. Now they sound a little better than my 8-year-old Kenwood 3-way 6 x 9"s, but my old Infinity Refenence 6.5"s sounded a lot brighter and more detailed... I bought these Polks because they should last a lot longer in the rear deck. UV rays and heat from the sun will deteriorate most speakers.( My old Infinity Reference 6 x 9" cones rotted away in 2 years time, but I should have covered them up with a towel or used a sun shade because that car sat in the driveway most of the time in direct sunlight.) As for my front door speakers, I transfered my old Infinitys to my other car so I still enjoy them... The Polk db vocals sound pretty good and they can handle moderate power (60W RMS), but I know first hand that the Infinity Reference have a "brighter" sound instead of the "warmer" sound that Polk db's produce. I am not familiar with the Polk Audio components or the Mobile Monitors, but I think in the future I will try Infinity Kappas- they should have a little more clarity and brightness. These Polk db's suit me just fine for now, as I listen to a variety of music including hard rock. They aren't bad for the money, but if you are not really on a budget, buy a quality amplifier and go for the Polk Mobile Monitors or Infinity Kappas- especially if you are into instrumental, bluegrass, or classical music.
The factory speakers on my Acura Legend were making buzzing noise so I thought it was time to change it. So, I bought set of Polk 6x9 and 6 1/2 to replace factory speakers which are paper base but it hits hard on the base which I like. But when I connected the Polk speakers, it was half as loud as the paper made speakers. I thought I connected the wires wrong but either way it sounded similar. I don't know how they do it but the engineers, they'll make gem out of rock I guess. Oh by the way, when I ordered these two pairs of Polks, the order didn't ship with any wires or wiring harness. None was included in the speaker box either. When I ordered the product online, it said it didn't require any extra harness. I ended up purchasing separate wires and a set of connectors to get the wires connected. I hate cutting and splicing original car speaker wires because I always end up loosing the original speaker plugs and it's messy with splicing on my own. I had to take apart the factory plug and get the wires out of the plugs without cutting the wires. Now, I am hesitant to swap the front speakers with 6 1/2 Polk because I'm going to loose all the base I enjoyed before. Right now I'm cranking up the volume much more to get the similar base effect. The sound detail is more clearer with Polk but from the rear speakers, you really want to hear the base. I'm thinking of trying out Infinity Kapa speakers soon.
Installed these in the cockpit of my 23' boat and hooked them up to a 40 watt x 2 head unit and WOW. They sound great. Lots of base, mid, and high end tones. Really sound great without an additional amp or speakers. I will probably add an amp down the road to get the full benefit of these speakers. Have no concerns, they will provide what you are looking for!!
I bought these to upgrade the factory speakers in my '06 Monte Carlo. The difference is night and day. The clarity is amazing.
Great sounding speakers but had one blow one month after the year warranty expired. I still have the stock stereo and no amplifier too. And to add insult to injury, they're only sold in pairs. Maybe I just got a lemon but they were great for short term listening enjoyment!
I modified the back of my 89 crx to fit these, and i get lots of bass in that small car. it satisfies me enough to hold off from purchasing a sub for a while. they demand a lot of power, so an amplifier will be needed in most cases, although my stereo (22 watts rms) holds it together quite well. Decent bass, decent price, clear highs. Im very satisfied with my purchase.
I got 2 of these in my 4 runner and i am running 2 12 inch subs off of the same amp and these things still scream!. You can hear it from the bottom of the road.! Not only that but it screams CRYSTAL clear.
One of the cleanest looking speakers in the entry-level bracket using a gunmetal color cone and not over-the-top grilles. Produce decent sound at low power (not so efficient if amplified considerably), especially if enclosed in a box, allowing it to produce decent mids and dip into the lows. Its also considered Marinized, making it an ideal speaker for installing in outdoor vehicles that don't see extreme weather (golf carts, mules, etc). All-in-all, a good performing, versatile speaker for the price.
This was my first time using Polk speakers. I will say it's my last. They have horrible mids and screachy highs. I feel like i'm listening to music inside a tin cup. I may upgrade to a higher quility Polk, but never would I suggest these speakers.
I purchased a pair of the 6x9 and 5 1/4" speakers to install in my vintage 1971 speedboat. Coupled with the infinity bass link and a Jensen head unit the system really rocks - hard! I have received a number of compliments on the sound system - for the sound and looks. Everyone likes the speakers - the grills are very nicely done - nothing overstated or cheesy with chrome. They have received a fair amount of splashed water and it hasn't damaged them. I wouldn't submerge them; however, they do prove to work well in a boat. I will be adding a pair of these to my 2007 Accord because the sound is amazing. On a boat the last thing you want is distortion at high volume to overcome the motor sound - these puppies really crank - loud and clear - and at lower volumes when we are tied up on a sand bar - look out you will get lots of people asking how did you get that to sound so good!!! It's fun - and the speakers are priced right!
Nice speakers. Very crisp and clean. Theyre not subs, but they do bump pretty good. Very clean bass. Pretty loud and just crystal clear.

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.
Woofer Cones: Each speaker features a Dynamic Balance polymer/mica composite mineral-filled cone. The cones are stiff and lightweight for big sound and low distortion.
Butyl Rubber Surrounds: For a smoother response and improved durability, the woofers use butyl rubber surrounds.
Kapton Voice Coil Former: The low-mass two-layer 25mm Kapton Voice Coil former is lightweight for high sound output. Kapton's high melting temperature (725°F) ensures high power handling and longer reliability.
Silk/Polymer Composite Tweeter and Super Tweeter: The speakers feature 1" liquid-cooled, silk/polymer composite tweeters and 3/4" liquid-cooled, silk/polymer composite super-tweeters for clearer, more accurate mids and highs.
2-way Crossover Network: The built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging.
Flat Spider: The speaker utilizes a flat spider for faster, longer excursion linear motion.
Pole Plate Heat Sink: The speaker's pole plate heat sink promotes better heat dissipation for superior power handling and reliability.
Woven Leads: The speaker features flexible woven leads sewn directly into the spider for greater reliability.
Basket: The speaker is housed in a solid, acoustically inert stamped steel basket finished in rustproof gun metal gray.
Grilles: Strong ABS plastic grilles are included. These computer optimized grilles are based on exclusive MOMO designs.
Marine Certification: Polk speakers are marine certified, making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals and crossover components are not covered, we do not recommend using them in salt water environments.
