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.

International customers please e-mail us with your shipping address and the number of units you are ordering for an accurate quote.  Shipping larger subwoofers internationally is largely determined by overall dimensions, so shipping two is often double the cost to ship a single unit.

“In Stock” orders have all parts on hand and will be assembled and shipped out within 3 weeks of ordering.
