Looking for loud bass? JBL built this MS Series MS-12SD4 12" subwoofer extra tough, with features like a vented cast aluminum frame and stitched fabric surround that help this sub hit hard and last a long time. This sub works equally well in both sealed and ported enclosures, so you can achieve virtually any bass tone you want, from punishing to mellow.
Versatile and powerful
The dual voice coil (DVC) design gives you more flexibility in matching your sub system's total impedance to your amplifier, in order to get maximum efficiency and full power. And speaking of power, this sub takes up to 900 watts RMS, for performance that'll let you really feel your music's pounding beat.
