PSB redefined high performance and high value with their legendary Alpha Series speakers and the new Alpha S10 active subwoofer continues that tradition in the all-important bass region. Though the S10 is compact and affordable, it gets down to business for music and home theater systems when deep bass is a must. The Alpha S10 meets the challenge featuring a long throw 10” woofer with polypropylene cone in a specially tuned bass reflex enclosure. Add DSP control and a state-of-the-art digital amplifier and the magic begins.
