Sometimes when the fishing is slow the speakers need to blow. The Polk sub woofer gives you an edge when over eager boats getting too close. I am sure if you are listening you can hear me from the boat landing sending low frequency vibes down to my finned friends in the underworld.

Great sounding subs. Good value, would recommended.

I had two of these in a ported box with a Hifonics Brutus 1200 watt amp and I was setting off car alarms all day! good buy..

I had this hooked up to an 800 watt amp and it blew out within a couple months. It may be my fault for overpowering the subwoofer too much. Make sure your amp doesn't overpower this one because other than that the sound was excellent.

I built a bandpass box for the 1st time. Polk has specs online which made it easy.

I owned a set of these previously in the DB1222 preloaded enclosure. Paired with a Rockford Power BD1000 they were insane. This sub paired with a Polk PA 400.1 is ok. I mostly listen to hard rock and metal and it is accurate and clean. It sounds decent for hip hop, but I found there was something to be desired . The specs say it's 360w RMS/720 peak, which means it should match perfectly with the Polk amp, but in my honest opinion I think it's underpowered having pushed a set with the Rockford amp mentioned above. Overall I am satisfied, but I think I'm going to go with a JBL sub in the near future.
