SINGLE 12 AMPLIFIED LOADED SLIM ENCLOSURE. Bass is our backbone here at PowerBass and our engineers have designed an affordable, yet powerful solution to put a new low in the bottom end of your sound system with PS-WB loaded woofer boxes. We take a unique design approach and engineer the woofers to fit the box, not the other way around like our competition. This gives our enclosures a deeper, tighter bass that handles more power for your hard earned cash. When you don’t have a lot of space for bass, we have our Amplified PS-AWB110T and 112T sealed “air suspension” truck enclosures that are designed to fit under or behind your seat that deliver tight, accurate bass.
