Nexo Alpha B1-15 Bass Module, The Alpha B1-15 is an advanced high power Bass module that can be stacked or flown together in arrays with Alpha M3, M8 and S2 cabinets. The B1-15 uses one NEXO specified high power 15 LF driver on an innovative internal flare component manufactured of rigid honeycomb composites. This high efficiency design delivers extremely low distortion, coherent bass output from 42Hz to 190Hz.

Like all NEXO products, Alpha System components are designed to work with advanced electronic processors, guaranteeing consistent performance and reliability of the highest standard.
