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. Specially tuned bass reflex design with rear port. Digital amplifier 150 Watts of Continuous Power. Compact cabinet volumes with high output. Woofers feature polypropylene cones and rubber surrounds. Design and final voicing engineered by Paul Barton.
