PSB Alpha B1
Our take on the PSB Alpha B1 by Crutchfield's Kristen Schaub
Compact, budget-friendly speakers
The Alpha B1s will show you what high-end sound is all about, but at a low-end price. Like every PSB speaker, they're designed to make sure you don't miss all the thrilling special effects and emotionally engaging sounds in your movies and music. You'll be amazed by their ability to produce clean, clear highs and mids that make your movies and music come to life. It's no wonder they're among PSB's best-selling speakers.
Excellence by design
PSB's engineers began by designing each Alpha speaker from scratch to ensure that they'll deliver the same level of performance typically found on speakers twice their price. The Alpha B1s use a 3/4" aluminum dome tweeter to deliver crisp, sparkling highs. The 5-1/4" woofers are made of metalized polypropylene, making them strong but lightweight. It means you'll hear excellent midrange detail and distinct bass without a trace of the listening fatigue that can happen with lesser speakers.
Build a complete Alpha system
Create a complete, budget-friendly Alpha home theater system using a combination of Alpha B1s in the front of your room, the C1 center channel, and either another pair of B1s or the LR1 satellite speakers in the back of your room. And don't forget to add a PSB powered subwoofer (or two) for room-thumping bass.
