The 4B10L from the BassInstinct ™ Series is an ultra lightweight dual 10″ cabinet with a 1.4″ driver and 90×60 horn. Weighting in at only 35LBS, the cabinet benefits from an ideally jointed and cross braced design, which adds to the rigidity and allows for the transducers to operate in their optical range. The result is a sound that brings new life to the bass and reproduces a uniquely beautiful tone. Italian Light Ply construction and a dual component polyurethane finish insure decades of performance.
