Summary: You don't know what you are missing to you hear this sub hit!! I have one of these in a 2009 Mustang GT and that is all you need. It even will make people look around on the highway, thinking there is something wrong with their car.
Summary: Love Polk audio subs! This sub replaced an old Polk DX series sub that I bought in 1997. The DX sub lasted 17 years and still looked brand new when it was cleaned up. This sub definitely hits a lot harder then the old DX. powered by a MTX 1502 thunder series 425 watts bridged.
Conclusion: first of all this is the best sub money can buy, highly recommended for those who love music, specially some deep bass. Pros: can handle all types of music, has good SPL potential, highly reliable, don't need much power even a small amp will do, looks cool, needs little space as compare to other...
Summary: Theses subs are awesome. I used to have some infinity subs but at very low frequencies could not duplicate correct notes... But these I'm hearing bass in songs that were meant to be heard. Amazing quality
Conclusion: These subs are incredible. I paired them with a 5000 watt (at 1 ohm) amp and they kick like a mother. I put 2 of them in an angled double 12" sealed sub box and they sound amazing. I love the sound they make in the sealed box, it is incredibly tight. They hit like no other sub i have heard.
Summary: I used to have JBL GTO's 1002D and I bought a pair of these guys. I was looking for great Efficiency and these are 92db Efficient. I'm powering the pair with Infinity's new Kappa amplifiers, 800 Watt (RMS) @ 2 ohms - Class-D Mono Subwoofer Amplifier.
