The 15mm (5/8") birch plywood enclosure consists of two dissimilar compartments, optimally ported to produce substantial sub-bass energy from a cabinet of extremely modest dimensions, and is finished in hard wearing semi matt black/optional white paint. The TCS110B has been designed to fit into small spaces or architectural features where a conventional bass unit would be impractical, and can therefore be installed discreetly under bars or stages, or even underneath seating, without affecting sonic performance. Integral M10 rigging points are also provided for easy suspension in fixed installs. Neutrik speakON NL4 and barrier strip connectors are provided for input and link through connections.
