An amazing 12" subwoofer. This will def. push some air for you and really make those lows really shake things.
This is the mistake many people make when buying speaker in a box systems. Many of those systems really give you satellites and a bass module. You really need a SUB-woofer to really create those amazing lows.
This is a sub-woofer that will shake your walls...why 12" and 1000watts in the built in power supply.
