The Nexo 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 Nexo Alpha 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. The B1-15 is fully capable of operating without the S2 subbass in applications where extreme LF performance is not required. The Alpha System is a range of advanced technology modular, compact, high power loudspeaker modules tailored for a wide range of touring and installed sound reinforcement applications, from clubs and theaters to large scale live events. Like all NEXO products, Alpha System components are designed to work with advanced electronic processors, guaranteeing consistent performance and reliability of the highest standard.
