Updated with our new PBX imprinted dustcap and sand blasted back plate finish, our XL subwoofers are designed to be bulletproof-reliable with all of the features of the rest of the Xtreme range, but in a more affordable package.
Boasting a custom turbine style frame constructed of polycarbonate/glass fiber, this unique basket supports dual stack magnets and a extended dome backplate.
We utilize a combination of perimeter and pole venting to keep air circulating over the voice coil so everything stays cool.
