BM-11

Description

Our highly praised shallow subwoofer is back! Our BM-11 puts a refreshing spin on the high-performance shallow subwoofer. We tooled up a new basket, a new Carbon Fiber flat diaphragm, and an all-new low profile S-surround to maximize ease of installation. The result is an 11″ subwoofer with only a 3.0″ mounting depth while still having 14 mm one-way Xmax. Getting proper bass out of a shallow subwoofer is challenging but we have the right recipe with our dual-gap 10 piece neo column shallow subwoofer. The multi-piece neo column motor drives an 8-layer copper voice coil through two magnetic gaps with a brass shorting ring directly in the middle to lower and linearize inductance for quick bass response. Linear piston movement of 14 mm one-way makes sure your bass is distortion-free during the most demanding program material. We optimized the custom tooled S surround to have the highest surface area possible while still allowing more than enough mechanical travel past the linear limits of the motor. Up front and personal is the beautiful glossy Carbon Fiber flat piston. A careful balance of motor strength and moving mass allows our BM-11 subwoofer to play a broader bandwidth than any other shallow subwoofer on the market. Mounting depth is only 3.0″ and physical weight is light at only 16 lbs.
