F18+ & F18-Slave Subwoofer

$1,195.00$2,495.00

The F18 is a highly flexible, modular subwoofer solution where each F18+ unit with its 4,000W amplifier can power itself, as well as 1, 2, or 3 additional F18-Slave units.  In-room extension to below 10Hz is possible in the largest to the smallest of spaces.  Slave units can be placed separately from the F18+ unit such as an F18+ in the left front corner, and a connected F18-Slave unit in the front right corner.

Black Maple and Rosenut F18+ & F18-Slave units are in stock and ship within 2 business days.

Flat rate shipping of $95 each within the lower 48 states.

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