SubMersive F2+ & F2-Slave Subwoofer


The SubMersive F2+ is a high power subwoofer solution utilizing a pair of 15″ sealed woofers on the front face of the enclosure.  Each F2+ unit with its 4,000W amplifier can power not only its own pair of sealed 15″ woofers, but also and additional SubMersive F2-Slave unit.  In-room extension to below 10Hz is possible in the largest to the smallest of spaces.  Slave units can be placed separately from the F2+ unit such as one F2+ in the left front corner, and a connected F2-Slave unit in the front right corner, or units can be stacked for greater headroom from the same footprint.

Flat rate shipping of $125 each within the lower 48 states.
