Alpha B1 Bookshelf
Sleek Design with Uncompromising Sound
Compact. Distinct. Effective.
For those seeking a compact, cost effective speaker, yet do not want to compromise sound quality for space, the Alpha B1 Bookshelf Speakers are the answer. We begin with a solid modular bass-reflex cabinet and load it with our newly designed, hand-built drivers and crossover network. The 5.25-inch woofer paired with a single .75-inch ferrofluid-cooled tweeter creates a 2-way design that is truly remarkable; and professional audio critics agree. Match the Alpha B1 to one of our compact subwoofers to create a powerful soundstage and discover for yourself why the Alpha B1 is among our best selling speakers.
