Product Description

Huge Bass. Compact Cost

alpha s8

PSB redefined high performance and high value with their legendary Alpha Series speakers and the new Alpha S8 powered subwoofer continues that tradition in the all-important bass region. The new Alpha S8 offers a more compact footprint at an affordable cost, while delivering big time for music and home theatre systems where bass is a must. The Alpha S8 meets this challenge by featuring a long throw 8” woofer with polypropylene cone (for fast response) in a specially-tuned, bass reflex enclosure.
