The WS2A is a dedicated subwoofer for use with Wavefront
Series full-range enclosures in situations where ultra-low
frequency enhancement and increased system headroom are
required.
It will extend the power bandwidth of the complete system to
below 35Hz and is capable of reproducing levels of deep bass
normally associated with much larger enclosures.
