Polk Audio db1240

I really didn't expect much when I got this sub, but I figured I'd give it a try. WOW... I LOVE this sub! I have Alpine Type-R 6.5's and 4x6's in my truck, my amp is an SPL Dynamics Z2X-820, and I made a 0.88 ft^3 sealed box (Polk's recommended). I have the sub bridged to the amp, with the gain about 3/4 and the sound quality is unmatched. Very good design, doesn't get hot, and keeps up with every style of music. This sub blends so well with my Type-R's, it brings a tear to my eye.

However, run the gain on the amp at full twang, filter out anything above 50hz, turn off everything that enhances bass, and she will do work. I have the sub and box mounted on top of the back seat (with hopes that the cushion would absorb some of the rattling) and my iPhone jumps around in my dash.

This subwoofer provides a good thump for its price which I would highly recommend.

I have a pair of these subs with 350 watts on them. A good pair of basic subs. More of a sound quality piece than an spl one. Very low air space was an important factor for me, at .88 each sealed, these fit the bill. I have learned that a 12 inch sub is perfect for me. This is my 10th plus set of subs.

So far so good i've only owned them for like a month now. I bought 4 of these subs for my 05 navigator running them with a 1500 watt rms power bass mono amp in a custom fiberglass box and they hit pretty good! all i gotta say is that you can hear me coming from a couple blocks away!!
