Conclusion: This sub is the thinnest depth full xmax driver i have found. Excellent sound quality, plenty of excursion- although i beleve the xmax listed is 2 way not 1 way making it closer to 14mm. Klippel says the 25mm xmax figure is actually p-p. Xmax is 14ish on the Polk as well according to klippel. Very happy with results on 2-300w rms.
Conclusion: I have 2 of these in a sealed box. I waited a few weeks to break them in a bit before I wrote a review. They have a tight, clean, crisp sound to them. They go pretty low as well. They will get louder after about 40 hours of play time. I've already heard a difference. My mirrors shake like crazy. If you want sound quality but don't want to spend JL Audio prices then these are for you.

Conclusion: i bought these, and would recommend them to anybody who wants a very well built sub for a very decent price. Sound is great out of a small enclosure, goes low, hits hard, everything i was expecting and more.
Conclusion: I've been running the MM1040 for 6 months now, and am always impressed with how powerful it is, while maintaining the clean sound Polk Audio is known for. I've since replaced all of my stock speakers with Polk Audio db Series speakers, and will stick with these from now on. I also love the clean look these subs have, what's with the cheesy deformed look of most subs these days? I get a ton of compliments on this sub.
Conclusion: The polk mm1040s replaced my jl 10w3s due to coils being burnt. I have to say the polks are louder and sound better than jl 10w3. I was skeptical at first due to jl's high quality and repetition. I tried the polk because their sensitivity rating was 7 points higher so i tried them. Now I believe I'm a polk fan. Just awesome subs!
Conclusion: I installed one of these in a truck an made a sealed box for it, and it sounded great! The quality was good, and for a slim sub woofer it hit hard. If you compare this slim design sub with others in its price range, you will see its rms power, sensitivity, and frequency response, is on average better. Great value, would definitely recommend it to anyone.
Conclusion: The 10" is a shallow sub with a full spider, magnet, and cone. Not a squashed version of a sub like other brands but, a true subwoofer built with a shallow mount. The sub produces true, deep lows as a subwoofer should. It's too bad that Polk audio discontinued this line. It is one of the better, shallow subwoofers. Feed it the specified watts and it will perform!!
Conclusion: Have this sub running off a Crunch 500.2 and it sounds great, could use at least 100 watts more to push it but it's doing fine. It hits some very distinguishable notes not noticed in 12" subs, it would be better to have range of bass than just the one, as 12" only allots for deeper notes and not some of the higher bass notes some music can utilize.
