Sonic Electronix is excited to introduce the BMF Subwoofer Series from Crossfire.

Crossfire BMF1228

Decent sub that is versitile due to the dual 4ohm voice coils. Paired with the right amount of power this sub offers great sound for the money and is sure to please a wide audience of listeners. I have it in a custom ported box, and the bass is tight and accurate without being overly boomy. Wish the xmax was a lil more as it would move a good deal more air from peak to peak, but again, you wont be disappointed with the end results.
