Powerbass XL-1240D 12" Subwoofer

Universal 12" 400W/800W DVC 4-Ohm Subwoofer by PowerBass®. Boasting a custom turbine style frame constructed of polycarbonate/glass fiber, this unique basket supports dual stack magnets and a extended dome backplate. They utilize a combination of perimeter and pole venting to keep air circulating over the voice coil so everything stays cool. A non-pressed paper cone was selected for its natural smooth bass reproduction and its ability to provide high output with low distortion even under the stress of high SPL. Finally, to make sure the power gets to the subwoofer, they used chrome push terminals for maximum current transfer. The XL subwoofers are Xtremely versatile and offer amazingly low bass whether installed in a small sealed enclosure or ported enclosure.
