The B218 Bass module uses two high-force 18″ drivers coupled in a common cavity loaded with a symmetric bass horn, computer optimised to guarantee ultra-low distortion, even at very high levels.

Using a 15 mm custom made bent plywood shell, with Poplar veneer for the inside layers and Birch for the outside, the B218 weighs in at 77kg/170lbs and achieves a peak SPL of 146dB. The low-frequency horn ensures maximum radiating surface and high efficiency.

Four large comfortable handles on each side plus one at the back of the unit ensure easy manipulation of the B218 in any situation, particularly when used with its dedicated wheel-board and cover.
