Alpha B1 Monitor
Compact. Distinct. Effective.
For those seeking a compact, cost effective speaker, yet do not want to compromise
sound quality for space, the Alpha B1 is 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.
