The Basson 300W, 8-ohm bottom-ported bass cab features a 15" Eminence Delta driver and a horn. Accentuates midrange sweetness, yet still lingers low to drive the bass line. The B15B is very articulate with punchy yet smooth and balanced low end. Features a "bell" tone that is big on the bottom but very clear through the mids and highs. Quality Basson craftsmanship includes durable carpet-covered cabinet, 1-1/4" braced reinforcement of all joints, and recessed steel handles. The cab is sealed air tight for amazing punch. 40Hz-4kHz frequency response
