Quoted from pinzrfun:I have 8 Polk subwoofers under 16 games. Hook up in 5 minutes, can hook up more than one game, tons of power and easy to unhook when I sell the game. And you can sell a subwoofer to anyone that owns a tv or stereo when the time comes.
That said, I'm probably gonna try one of those $20 cabinet speakers just for kicks. I have nothing better to do.
Polk 8 or 10" sub's are the best option for sure.
