About the PSB Alpha C1

Thrilling home theater on a budget

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 C1 uses a 3/4" aluminum dome tweeter to deliver crisp, sparkling highs. The dual 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. The two woofers flank the tweeter in an array that increases the C1's on- and off-axis response, so everyone on your couch can enjoy the same, great PSB sound.

Thrilling home theater on a budget

Anchor the center of your home theater with the Alpha C1 center channel and reap the sonic rewards. Its excellent midrange and low frequency response allows it to easily handle the complex on-screen action and dialogue in all your movies, TV shows, and video games. You'll be amazed that a speaker of this size — and price point — can deliver such a wide soundstage filled with crisp, accurate detail. So sit back, relax, and let PSB show you what a home theater on a budget can really do.

Excellence by design

Build a complete Alpha system

Create a complete, budget-friendly Alpha home theater system using the C1 center channel and a combination of Alpha T1s floor-standing speakers in the front of your room and either the B1 bookshelf speakers or 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.
