Polk Audio AA2651-A Review by Jay_Castro "Javier Castro Jim�nez" (Santa Ana, San Jos� Costa Rica)
These are great speakers, mostly because they don't distort even at high volume and for the build quality, technologies used and materials chosen to build them, but how they sound, good or bad, depends on the way you like to listen to your music. So this speakers have a high sensitivity rating of 94 dB @ 1 V, this could be one of the reason why they are so bright in the mids and highs. I had to lower almost to the limit, all the eq bands of 1.25kHz, 2kHz, 3.15kHz, 5kHz, 8kHz and 12.5kHz on my head unit's eq, because of how bright these speakers get. They have a precise high definition for the vocals and highs, like cymbals etc, a crisp tweeter, with no harshness, but at lower volume levels. So again it is not that they are harsh which is a different thing, what they are is extremely sensitive and bright. If you crank it up from 50 % and up of the HU volume knob, they get really bright loud. I would say if you do not have external high power amplifier these speakers will be a great choice for OEM Head Unit or aftermarket Head Units power. Also be sure to hook them up with the included passive crossover box, if not you would not get the best out of them. I was powering them with an Alpine amp, model MRP-F300, 50w rms x 4, at 4 ohm, so these speakers were being fef by around 30 to 40 watts rms max (counting the normal ineficiency of class AB amplifiers)and they got really bright loud. Any way I would still recomend this speaker for it's build quality and materials and for people who only have the stock head unit or aftermarket head unit or for who ever has an external amplifier and likes bright sounding speakers, and again is not like they have a metallic tweeter sound like metal tweeter, since this have a silk soft dome tweeters, it just the overall brightness of the speaker, possibly caused by the high sensitivity of 94 db that they have. For the record I have had them for around 6 months, so this review is way after the break period of speakers and after several fine tunnings of amp and head unit. I will replace this speakers. At some point for what I described above, but I could have live with their brightess if it wasn't for that on one of the speakers the woofer died. Since the beggining it had a lot of distortion at 50 % volume or more until the point it just stopped working at all. This is ok, this does not mean they are bad quality speakers, it could just be that it was factory defective or that I might have gotten damaged because I did not use the included passive cross over during the first 5 months of the 6 months that I have had them, but it would be kind of weird because the other speaker sounds just fine. So I am stuck with a pair of good speakers that on one of them the woofer died and left only the tweeter sounding and I live in Costa Rica, so sending the speakers to Polk Audio for warranty will end up costing me half of what I could pay for another decent set of speakers. So this time I will give the Pioneer Premier TS-D602P 6.5-Inch 2-Way speakers a try, they have a sensitivity rating of 88 db, so I hope they will suit my listening demands.
Polk Audio AA2651-A Review by Andrew Anderson
I have these in the back doors of my tahoe and the polk mm components in the front, they sound great. Better than kicker,infinity and alpine(all which I have bought before in other vehicles). Very good midrange and ear pleasing highs, no harshness at all.
Polk Audio AA2651-A Review by VHP (Houston, TX United States)
These were installed in the front and rear doors of a 2007 Inifinty M35 with the base radio. I have been complaining to the auto dealer that there was no depth or clarity to the sound. The dealer rep said no one changes out the Infinity system because they are so good. I talked to installation shops and some said don't change the speakers because they are of such good quality add a amp, others said change the speakers. Confused I called Polk help and was advised to try the speakers first. These MM651 speakers make my system awesome. I play the radio at low to medium volume and the sound is superior, I now hear music with great claity and definition. The sound is now better with the basic stock Infiniti radio than the ultra premium Bose that I have in my Audi A6. I am totally satisified and really appreciate the help from the Polk reps.
