The Alpha S2 is an advanced high power Subbass module that can be stacked or flown together in arrays with Alpha M3, M8 and B1 and Alphae Series cabinets. The S2 uses two Nexo specified high power 18" long excursion LF drivers in a high efficiency resonator design combined with low speed port geometry to deliver low distortion, coherent output from 32Hz to 64Hz. The S2 provides optional VLF extension of the frequency response of Alphae Series and Alpha Systems to 32Hz.
