The 1" silk/polymer tweeted can be surface- or flush-mounted for better imaging.
Go ahead, circle the parking lot till your favorite song is over. Polk Audio's DXi Series speakers will make you want to hit "repeat" so you can hear it all over again. Polk uses a high-tech approach and ideal materials to give your tunes an exciting new edge.
Polk's DXi6501 component speaker system features 6-1/2" polymer composite cones that are lightweight and stiff, so they can create a big sound with minimal distortion. Polk analyzes their drivers in motion to ensure that cone movement is even and precise. Polk also uses laser imaging to craft woofer cones that are perfectly balanced to resist distortion-causing resonances.
Rest assured, you'll hear every detail of your most enthralling musical moments. Each 1" silk/polymer dome tweeter brings out the high-frequency highlights in your music, and a proprietary magnetic liquid cools the tweeters so you'll get clear sound and excellent long-term performance. You can set your own stage — surface- or flush-mount the tweeters with the included swivel-mount cups, and aim the tweeters towards your ears so you can really enjoy the show.
Polk includes high-quality crossover networks that create a smooth transition between woofer and tweeter, so you'll hear accurate, balanced performance from this system. From an intensely quiet acoustic pluck to the most exhilarating electric solo, it'll be a very entertaining ride.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.
A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.
I just installed these speakers to replace my Alpine 6.5" co axials that were blown. These things can take some power, and stay crystal clear. I would recommend these to a friend or family member in a heart beat. Putting the tweeters on the dash angled towards the center of the vehicle and slightly up towards the head makes the highs bright and clear. The easy adjustable 9 db swing on the passive crossover makes it even easier to adjust the sound from left to right. Great gear.
Pros: Great sound and clarity, and still clear at higher volumes
Cons: none so far.
Excellent product, sleek and elegant design. Sound fabulous. Crossover is a bit bulky especially when trying to fit somewhere into a door panel, but other than that easy install.
A tough install in my 07 pony , but with a little ingenuity and creativity nice install , put 6" in 8" woofer location had to leave 8" grill on and cut out 6-1/2" opening in it using new grill as template . Put crossover in 4x6 speaker location using Velcro in door ,wanted to put tweeter in A-frame location but couldn't because mirror control was there, so flush mounted in spot close to raised lock push opening, worked out perfectly, sound is directly in my ear .the hardest part was thinking how to place the woofer ,total install time @ 2-3 hours both doors set crossover to 0 better to adjust from head unit control's
Pros: Much clearer sound stage
Cons: Have to use your ingenuity to fit in a mustang stock doors ,but it is possible .
installation really easy for someone who has done this type of thing. replaced factory speakers. very happy with the purchase.
Pros: clear sound at all ranges. reasonably priced.
Cons: instructions weren't very helpful for installation of tweeter. we came up with a simpler solution
Excellent build and sound quality.great bang for your buck!
Replaced the factory front speakers in my Toyota Tundra 2010. What a difference!!!
nice with the subwoofer and amp. with the right amount of power it does very well
Pros: nice for mids and highs
Cons: needs power
Not the best for a factory head unit, but really woke up when paired with an alpine power pack. Used these to replace some factory 6x9's in a 2014 Toyota Tacoma.
Pros: Amazing sound
Polk speakers are by far the best speakers I have ever owned I first installed them without an amp and they sounded awesome and Then amped them unbelievable!love them!
Pros: Great speaker all around
Cons: The speaker connection terminals seem cheap and flimsy to me I wish you would make better connections
Ordered these speakers for the rms rating. But they under perform. I have a set of pioneers that have half the rating. They knock the socks of these. Sound qaulity is poor. Had to exchange them due to tweeter issue
Pros: Not really sure
Cons: Rms rating is not correct. Performs poorly. Sound is not clear and crisp
This is the first pair of Polk speakers I have purchased. I previously had MB Quart, which were fantastic. The Polk speakers surpassed the MB Quart in clarity and easily handled the power from the amplifier. I will be replacing the remaining pair of MB Quart with the Polk Audio DXi6501. I highly recommend Polk Speakers.
Pros: Good price for the quality. Installation was easy
Cons: None that I can see.
Great set of speakers. Crutchfield has the best svc hands down. I wouldn't buy any were else.
Pros: Great set of speakers for the money
Easy install, I am getting a tinny sound from the highs. It is ran off a Kenwood excelon deck with no added amp. Iv tried adjusting it and the only way I can get that sound to go away is to turn down treble quite a bit and turn up the mid. Hoping it goes away with time or maybe with an amp install for the speakers. Other people have said the speakers need an amp to get full pormtential out of them.
Pros: Easy install, appear will built
Cons: Tinny sounding high notes
For the money a good investment. Good sound most of the time. Deep bass sometimes sounds like it has a little crackle. I could not pop the tweeters out of there holder. Ended up just using the friction from the holder in the door. Could not use the bracket. I was afraid to pry it out as I may damage it.
Pros: great for the money. Easy to install
Cons: could not use bracket on tweeter
I like the speakers. We used dynomat to make the sound better. Speakers sound very good. Tweeters can be a little bright so we may switch db down some. Went in the car very easy. Good purchase
Pros: Great sound and easy install. Use Dynomat to make sound better
Cons: Tweeters may be a little bright but you can adjust
great sounding speakers. huge upgrade from factory. couldnt be happier
Great sound for the price. The adjustible tweeters high or low are nice. Easy to istall with the free install gear Crutchfield throws in. Plenty of wire to run my tweeters from the crossovers to the pillars. Overall a very nice set of speakers.
Pros: Sound quality, value
Cons: Crossover is a little thick
Needed to replace Bose speakers (Front Doors) on a Nissan Altima. These did the job very well. Installing was quick and easy for the front door, however I haven't gone after the tweeters as free time around the holidays is in short supply. I also replaced the speakers in the rear door with Kicker 41DSC54 speakers.
Pros: Crisp sound, anything sounds better than deformed speakers.
Cons: None right now.
Very nice upgrade for my Trailblazers factory speakers
Pros: Sound and look of speakers
Bought these to replace the stock door woofers and dash tweeters in my son's 2003 Jeep Liberty. Door install was asnap, plenty of room to mount the crossovers behind the panel. The tweeters were more of a challenge, but we fabbed some brackets and managed to mount them in the same position. Sounds great, much more definition and clarity than the old stock speakers.
These speakers are ok but the tweeters sound very twangy and there is alot of voice going through them .i haven't hooked them up an amp yet .but i don't think it's going to help. I should of just got the the regular speakers and not the component and used the factor tweeters .so for me it was not worth the money.
Pros: Nice packaging
Cons: Voice sounds twangy and unnatural from teeters .also the frame on the 6.5 isn't very sturdy.
I am disappointed with the tweeters. Although they are silk/poly dome tweeters, which should sound warm, they sound tinny, thin, metallic. I used two different amplifiers without any change. The first was 45 watt per channel amp. The second is a 120 watt per channel amp. Sounds the same. Tweeter sounds the same, scratchy and tinny. I've used Polk speakers for ever. Usually, they're great. Not here.
Also, mounting screws weren't the right length for the woofers.
Pros: Polk. 100 watts per channel handling.
Cons: Tweeters not right sounding.
Pros: Good desing
Cons: You buy ths speaker under you own risk. If you dont have an amplifier at least 125 watts rms . Dont intent buy this speaker. I have an amplifier infinity reference 475a 75 rms watts and the speaker and this speaker has a big distortion . Bass sound as a cheap speaker may be 30. Dollar. I willing to pay for this speaker 30.00 dollar. An amplifier in Crutchfield 125 rms watts or more are very expensive. If you have money do it. Not warranty has good sound. Check other speaker please.
Great sound and very reasonable price.
These are pretty nice speakers, been running them for about a week. The tweeters are running off my alpine HU and the woofers are connected to a two channel amp pushing 75W. I ran the tweeters through the supplied crossover and the woofers are using the crossover on the amp. Took some time to dial in the right sound but for the money they are pretty good. Not competition winning sound but decent sound on a budget.
Pros: Affordable and nice sound.
Cons: Not very good at high power. Don't go over the recommended RMS or they won't handle it.
Somehow I made it many years with the "Premium" factory system in my 1999 Saturn SW2. Moved up to a Pioneer basic CD receiver a year ago and it was able to reveal the deficiencies. Have a Polk 10" woofer in a custom cabinet and drive it with about 90w from an old Sony amp I picked up from Crutchfield in the early 90s. Prior to the DXi6501 upgrade I had added surface mount tweeters on the upper dash and padded them with 30 ohm series resistors. Still too bright. But it let me hear about higher tweeters - the SW2 location is into my calves. Did not want to get the tweeters too high so I settled for about 10 " up from the woofer, in the plastic in front of the fuzzy door covering with the window controls and latch. Mounted the crossovers in the door in such a way that I can reach the tweeter switch without removing too much. Stereo imaging is not like the showroom, after all I am sitting between them and they are not at ear level. Clarity and openness are vast improvement, I am hearing more details. Let my wife listen to an Il Divo CD and it brought tears to her eyes. These speakers were on sale and for the price I am very happy. Gave them 4 stars because they don't sound like much more expensive units; a great value but not amazing. This is my first experience with components with passive crossovers (I have used electronic crossovers with 3 stereo amps in other vehicles) - it is definitely better than the standard coax with a series cap.
Pros: Significant upgrade in clarity. I feel that my basic head's 20 watts are adequate (with a separate powered woofer). Usual superlative assistance from the Crutchfield team.
Cons: Tweeter mounting bracket for flush mount did not have enough tang length for my thin plastic door panels and I had to use a little gaffer tape to secure them. Door mounting crossovers means they would be hard to adjust in this vehicle, so I spent some hours with them on the bench before committing to the flat setting. Research, experience and testing meant 10 hours to get the first one in and 2 hours for the second - Saturn latches are very hard to get back in - watch for tricky swivel clips.
These fit perfectly in the rear doors of my 2001 GMC Sierra 2500 HD Crew Cab in spite of Crutchfield saying they would not. Actually bought them for the front doors, but decided to put them in the back when I saw they would fit. I did have to drill a hole for the tweeters, but that is expected. Sound great. Very happy with the speakers.
Pros: Fit Sound
Cons: Crutchfield error in their fitament data.
Sweet, clear sound. Very happy. Woofers fit perfectly, Crutchfield-supplied wiring adapter worked well. Tweeter mounting was a problem until I read somewhere to use Dynamat, that real sticky sound-deadener sheet stuff. Actually I used a cheap hardware store version, Quick Roof: very sticky. The tweeter had to mount in the door behind the existing curved grill. There was no flat mounting surface, so I cut an x-shaped slit in a piece of the mat and pushed it over the tweeter, then stuck the whole thing to the inner door panel. I used the same mat stuff to attach the crossover to the door near where I cut into the harness for the wiring. No wire splicing needed. Car has existing amp used for 2-ohm speakers, I kept it even tho these are 4-oms. Need to crank the volume up a bit (around 30 to 50%), but it gets plenty loud for me, no distortion. BTW the local car stereo shop wanted a little under $200 to install these. I also bought some Quick Roof and I slathered it all over the inside of the doors for sound deadening.
Pros: Smooth sound, not bad installation.
Cons: I can see tweeter installation being a problem for some.
Great product for the money, looks great.
Despite the claims on Crutchfield site this item does NOT fit a 2013 Wrangler Unlimited. The tweeters in this kit have a huge lip that prevents them from being placed in the factory holes in the dash, at least not without trimming the bottom and then having plastic extend beyond the dash holes around the rest of the circumference. Apparently I'm expected to disassemble the tweeter from the Polk casing and then disassemble the factory tweeter to try and use the factory screen. Probably not difficult but I expect it to fit if the site advertises it as such. My first purchase here is a HUGE disappointment. Any suggestions on kits that work out of the box? These are going back as soon as I have time to waste arranging shipping.
Cons:Crutchfield response on July 2, 2014 Our database can only check the woofer locations for fit. Tweeters are always a custom installation and only rarely will they drop right into the factory housings. The customer can definitely return the speakers and our advisors will be happy to help find something that'll work out better.
I was well pleased with this set! Once installed with an amp of equal capabilities they sounded very good! The high notes hit well and a decent amount of mid as well. Ver clear and aggressive sound! I could turn it up loud enough to the point you don't want it louder! Another great Polk product!!!
If your looking for a cheap setup for your vehicle then this is not it. Factory radio's suck. The ohms matter. Put in a head unit THEN listen to your factory speakers.. Sounds like crap right? Then replace the speakers keeping the same head unit. Sounds a lot better right? I have mine running off of an amp and you can hear me coming down the road.
Pros: Sounds amazing in my 2002 taco 4 wheel drive. Paired with my Fosgate P4's and amps I say it kicks butt!!!
Cons: Sounds great if you have an aftermarket head unit. Add an extra amp and you will hear sounds that you have never heard before
These are amazing speakers for the price they sound great in my PT Cruiser and I am so glad I purchased them, there are not many that fit the car but these do and I am glad!
Pros: Love them, easy install, nothing bad to say!
purchased on recommendation of Crutchfield to replace factory Toyota speakers. They don't fit existing speaker brackets which have to be used to clear window. Further, now my door panel will not snap back flush. Sound is also not really any better than the speakers I replaced. A waste of 8 hours and 3 days.
Cons: sound average and they do not fit standard 6 inch speaker bracketCrutchfield response on June 10, 2014 We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.
Excellent product! Sounds great!
Pros: Highs sounds great for the tweeters.
I purchased these to replace my factory speakers. The sound is really clear. I can hear things in the music I have not heard prior. The only thing right now is the highs are very shrilling and harsh. I hope once they "break in" the sound will settle in.
Pros: Great clear sound..very crystal clear
Cons: highs are very harsh..
Sound great in a 2010 Tacoma SR5
Pros: Sound great with factory head unit. Easy install. Need to remove factory tweeters and run new wires. Crossover mounted to door under arm rest
Great upgrade to factory speakers, Great sound!!!
Pros: Great speakers
Purchased these to replace the front door speakers in my 2011 CTS with Factory Bose system. I was hoping to get better bass response form these vs. the stock speakers. The purpose of this review is not really to knock the speakers, I'm a big fan of Polk. However, these just aren't a good replacement (and I'm guessing no 6.5" speaker would be) for the he 2011 CTS. The issue is that with this particular speaker, you have to use Crutchfield's speaker adapter plate AND the plate that comes with the speaker. the two do fit together but it's a less than ideal foundation. Secondly, and more importantly, these are 4OHM speakers and the factory are 2OHM. I questioned this with a sales rep prior to purchase and was told that there would be no appreciable difference - WRONG! The final reason why these just don't perform well against the stock speaker is that the factory Bose front door speaker is 8" in diameter (not 6.75" as many place state). After mounting the left side front, I did a left to right sound comparison and the stock speaker was louder, deeper, and richer in sound than the polk. A very disappointing result. FYI, I wasn't planning to switch out the tweeters because the stock system is pre-crossed at the amp and the cross-over on the polk is set at a different frequency (3k).
Pros: Good Build Quality
Cons: Didn't work out for my application.
Don't really have any negatives about this, or any of the four different Polk products I've owned in the past.
Pros: Great sound, great build quality, great price
Cons: none, and none
I've had these installed in my new Focus for about three months. I find that the highs are way to harsh for my listening preferences, and the bass is only moderate. I am not a certified installer, but I definitely know what I'm doing, as I install aviation systems and car systems regularly. I installed these myself, so the sound quality didn't suffer from the install. The speakers and outboard crossovers definitely feel of high quality, better than most in this price range. Unfortunately, that's about where the good stuff ends. I've hooked up multiple brands (and power levels) of amplifiers to these speakers, and they only sounded "good" when I was pushing them with almost 120 watts RMS. So I suppose they can at least handle their recommended rms rating, that's good, but they still didn't sound all that great. Another reviewer claimed that they have an exorbitant (long) break-in period, and I definitely agree. It took about 30 hours of play before the bass tightened up. I wouldn't purchase these again. If your heart is set on these, then do yourself a favor and invest in a high-powered amp.
Pros: Feel of high quality speakers. Comes with versatile and good-quality mounting adapter rings.
Cons: Just about everything else
I used this to replace the stock front speakers in my Saturn Sky and I'm amazed at the sound quality!
Pros: Quality, sound and price. Polk knows how to make speakers.
Cons: You will need to purchase an amp to drive this babies, but it's worth the investment.
Really improved the sound of my 2014 Subaru Legacy by using these Polk speakers
Pros: Crutchfield did a great job installing the speakers
Good brand, sounds great in the jeep. Hoping they last a long time.
Pros: Sounds good
Crisp clear sound. Great speakers
Pros: Price- got them on sale
Speakers are great. Loud at low volumes. Hearing things in my music that I've never heard before
Cons: If anything, not much on the low end. But these speakers coupled with a good sub and everything should be great
I installed these in the front of my 2013 Honda Civic Si Sedan with factory nav. I will say I did not try them off the factory amplifier. Instead I ran them to a 5 channel Kicker unit. With that being said, I installed these tweeters into the factory location. I did mangle the factory tweeters to remove them to put these in the factory bracket. It worked though. I put the mid range woofer in the front doors and used foam baffles behind them to tighten up the sound. These units sound incredible. Nice crisp clean sound. I have run many brands of speakers over the years. These are right up there in quality and for the price you just cant at them. I am pleased with them. They have a little low end kick to them but certainly not boomy. If you want the low end bass you need a subwoofer setup. Ive got these set on a high pass filter at 50hz on up. The subwoofers take care of 50hz and below. It sounds fantastic on all different types of music. Country to pop and everything in between. I have no complaints. The cross overs are nice and small i mounted mine in the kick panels. Out of sight out of mind but easy access for adjustment purposes.
Pros: Great value and sound for the price.
Due to mishandling on an unrelated repair job, the front door speaker on the driver's side had developed a buzz which couldn't be repaired. The Crutchfield Catalog's timely arrival with the offer of Polk speakers on sale ensured that we would make the purchase. Wise decision as the speakers went in easily. Now, we are treated to clean sound and no distortion at either the treble or bass end of the spectrum. We are quite pleased with the speakers and will recommend them to our friends.
Pros: Installation was quick and easy.
I purchased these speakers as the first step in upgrading the sound system in my 2006 Sienna minivan. With my son turning 16 and in need of a car I felt I would be driving the van for the next four or five years so I decided I might as well enjoy it. My long term goal is to build a high fidelity system capable of matching the sound quality of my home stereo. The next step will be to replace the factory head unit and install amplifiers and subs. The speakers were easy to mount using Crutchfield's brackets (with some minor adjustments to the rear brackets to fit the existing mounting points. I will admit I have noticed a significant loss of bass response with the Polk speakers. However, I expected as much given their smaller size. The high-ends are amazingly crisp and the midrange response seems very accurate. Once I finish adding the other components I'll update this post.
Pros: construction, sound reproduction
Cons: None so far.
Sounds Great. I was able to take apart the original tweeters in a Jeep Wrangle JK and slide the Polk Tweeters inside. I did have to cut part of the original tweeter housing to be able to snap on the original grill. Very happy with the finished product. Any everything looks factory.
Pros: Sounds great
I upgraded to these speakers as part of a complete upgrade from the factory system in a 2006 Civic. I don't know how much of the improvement is in the speakers and how much is due to the excelon head unit and 75W/ch amp. However the system as a whole sounds sublime. I was skeptical of the specified low frequency limit but I send them the full range signal from the amp and they have no trouble accurately reproducing the tone and volume of a double bass (Edgar Meyer provides my test music). I do not have a sub and I do not feel like I need one for the music I listen to - mostly bluegrass, jazz and classical with the occasional prog rock. Midrange (guitars, male vocals...) sounds full and warm and highs are crystal clear. It sounds like the band is in the car with me, which is to say that the imaging is also excellent. These speakers had the most pronounced break-in period I have ever experienced. For a few hours they were actually shrill and painful to listen to at any decent volume. That passed and they continued to improve for another week (maybe 10 hours listening) and they have stabilized at two weeks. I can't say with certainty that this wasn't due to the amp burning in instead of the speakers since I upgraded all at once. If you want natural sounding music with accurate bass, these are perfect. If you want explosive bass that can be heard for miles you will need a sub, but would probably still want these too.
Pros: accurate bass, warm midrange and crisp clear highs. Excellent imaging.
Cons: I'm paying more for gas now that I take the long way everywhere I go.
Bass is rohbust
Received as a gift. Very smooth, wide range for this size. Very good treble and midrange, fair, smooth bass; 6 1/2 speaker can't be expected to compete with larger sizes of similar quality. Polk seems to be aiming at quality of sound, for a natural, accurate image rather than for the "boom boom" type of consumer. I was able to fit everything in my Prius, which came with the JBL system. The woofers came with adapters that fit the woofers perfectly. I was able to fit the tweeters in the original spots, with simply a bit of cutting away the thin plastic that held the poor quality JBL tweeters (shame on JBL!). The tweeters are very efficient, so I set the level on the crossover to the lowest setting. I bought the Polk 3 1/2" two way speaker from Crutchfield for the center speaker, very efficient, fine tweeter. Good advice from Crutchfield. I think these speakers would fit most cars, more than Crutchfield recommends. I added some sound deadening to the doors. I may add an 8" subwoofer later, but for now the bass is satisfactory due to the naturalness of the sound.
Pros: Very smooth, natural, accurate, musical, detailed sound. Tweeters will reproduce highest musical frequencies. Will play loud, too. Can handle more power than rated, with ease.
Cons: None. Bass is as good or better than expected for its size.
These speakers sound pretty good. I wasn't blown away by them, but they're solid. The grill is huge, and I had to cut it to fit into the car since it was in the door panel and stuck out enough to hit the dash. I had to abandon the screws that came with it as well as they are only designed to be used with the sheet metal nuts that came with them. The tweeters are only meant to fit either recessed or flush on a flat surface so I had to modify them as well to fit my cars curves.
Pros: Good sound, good value, looks nice
Cons: Not very versatile for installation, speaker grill too large

High Efficiency Design: The Polk Audio DXi Series speakers feature a high efficiency design; meaning better sound and more volume using less power.
Dynamic Balance Driver Technology: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials creates the least resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.
Klippel Optimized Components: For a driver to reproduce complex sounds accurately, the cone must move exactly the same distance and manner in both directions. The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Polk optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
Composite Cones: Each woofer features a Dynamic Balance, Bi-Laminate composite, polypropylene cone woofer. These composite cones feature tremendous stiffness-to mass ratio, resulting in faster transients and finer detail.
Rubber Surrounds: For a smoother response and improved durability, the speaker uses rubber surrounds.
Mounting: Out of the box the DXi 6501 woofers are a direct replacement for many standard 6-3/4" applications. Mounting brackets are included with holes matching standard 6-1/2" (3-hole), Ford 6-1/2" (asymmetrical 4-hole), and various 6-3/4" applications. Without using the mounting brackets the speaker also fits into many standard 6-1/2" openings, but the four hole pattern is not a direct replacement (new screw holes would need to be drilled; in this instance mounting depth would be 1.947" and mounting height 0.427"; this application does not sort in the Crutchfield Vehicle Selector because using the mounting bracket requires no modification, and is therefore the preferred 6-1/2" mounting method).
Silk Dome Tweeters: The 1" liquid-cooled, silk/polymer composite dome tweeters provide clear, detailed highs.
Neodymium Magnets: Each tweeter employs a light-weight neodymium magnet for better efficiency.
Mounting: The supplied mounting cups allow you to surface or flush mount the tweeters. The tweeters swivel in the flush-mount housings, allowing you to adjust them for optimum imaging.
Tweeter Mounting Dimensions:
|Surface Mount||Flush Mount|
|Depth||0.21" (screw depth)||1.082"|
Design: The outboard 2-way Butterworth crossovers have a 12 dB/octave slope (high-pass and low-pass).
Tweeter Level Switch: You can adjust the output of the tweeter to match a level appropriate to your vehicle or your system. On the end of crossover (opposite the terminals) the switch can be set to -3 dB, 0 dB, or +3 dB.
Protection Circuit: Each crossover has a built-in electronic circuit that protects the tweeter from accidental overdriving.
Connections: The crossover inputs and outputs are screw terminals. The terminals will accommodate the included wire or spade connectors up to 0.3" wide.
Mounting: There are two mounting holes in the base of each crossover; the cover must be removed to install the mounting screws.

Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Krissy Nov 23, 2015 ] Staff
I forwarded your question to an Advisor and they responded with the following: These speakers will sound great with an Alpine KTU 445U power pack. 45w of power is more than enough to play clear audio at moderate/loud levels. The Polk speakers are fairly efficient, so they do not require as much power as most other speakers. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Jan 13, 2015 ] Staff
For the 6501s... no, you TECHNICALLY don't need an amp, but a standard aftermarket head unit is only continually pushing about 20 watts per channel. They will sound good, but not really any better than the dxi651s, the coaxial set, without a lot of power. You're better off saving your money if you aren't going to amplify these. However, I DO really recommend the 651s. They'll sound just as good if you aren't amplifying them. [ Derek Apr 28, 2014 ]

I don't see a picture listed for the grilles on this speaker. However, I would expect them to be similar to the grilles from other speakers in this line from Polk. [ Jeff Nov 25, 2013 ] Staff
