XL-840D 8" SUBWOOFER WITH XTRA LARGE BASS
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.
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, we 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 and are available in 8”, 10” & 12”
