Polk Audio MM652 6.5" Coaxial Speakers + Sound Dampening Kit - Customer Ratings & Reviews

Don't go without it

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

NVX SDBSK2 Premium Stealth Black

Thick and heavy. I was suprised with the actual quality. For the price they’re great quality

NVX SDBSK2 Premium Stealth Black

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.

Easy to use and reduced vibration, allowing clear sound coming from my door speakers.

Great value

I installed these on each rear door of my 2005 Silverado. Could really hear a difference in sound quality.

Polk Audio MM652 - MM1 Series 6.5" Coaxial Speakers

Polk Audio MM652 is the best marine grade speakers I've ever used in $150 to $200 price range. I use then in my boat and UTV.

great product

good product , loud and clear sound , marine product excellent . will recommend the product .

Sound so great on all volume levels

I'd recommended for sure and also recommend running on an amp to get the full specs of these speakers. They sound great even at low volume, the bass still kicks good. Just what I wanted out of them, so it was the right purchase for my needs. Good solid sound.

Best bang for buck

Great speakers for anyone looking to upgrade their factory Harley Davidson speakers. Way better than the boom audio upgrades.

Polk Audio MM652 - MM1 Series 6.5" Coaxial Speakers

Polk audio,great sound quality and marine grade components, only way to go!

Robust music for open spaces.

Installed in a Wrangler YJ in a front sound pod. Selected for Marine rating and good 'sound' reviews...Yes! Excellent for my open bodied ride with plenty of clear, crisp volume from the Sony head unit. Overcomes road noise quite well without needing to go into nuclear sound mode.Installation was straightforward, but the grilles needed a 'touch' modification in my specific install. The sound range is substantial, but I will add in a sub shortly to compensate for road and exhaust noise on the bottom.

It’s Polk audio can’t go wrong

Great sound with an amp giving its RMS. Polk always has quality products.

Excellent

I added these to my boat along with 2 pairs of infinity marine speakers. The infinity speakers sound very good and are 1/2 as much but these sound great. I would highly recommend.

The only negative I can think of is the grill is designed with relatively large hole where the speaker could get damaged. Hopefully this own happen

Sound deadening

Makes the speakers sound great and looks good to plus doesn’t blind you.

Good deal

Bought a pair of kickers and they came for free, doubted them at first but it really does help in muffling the rattles from the speakers.

GOOD QUALITY AND EASIER ON THE HANDS!!!!

I got this small pack to finish my daughter's 2020 Camry after I had already used the foil-backed version. It went on just as easily and stopped the license plate and gas gap door rattle. A big plus for me was it didn't cut my hands shreds as the foil did.

Good quality sound deadener.

Not enough to cover an entire door but enough to add enough mass to make a difference. Peel and stick.

Polk Audio MM652 - MM1 Series 6.5" Coaxial Speakers FREE Sound Dampening Kit

Nice clear sounding speakers. The actual woofer looks small though and the magnet was also pretty small. However they do the job.

Who does that anymore? Free product great service free shipping that’s why sonic’s electronics is growing and other companies are not.
