Meet the Alpha T20
The PSB Alpha T20 Tower Floorstanding Speaker (Each) is the floorstanding model in PSB’s Alpha Series, built to deliver full-bodied sound, strong bass extension, and the brand’s signature natural tonal balance in a room-friendly cabinet. Its compact tower format combines dual 5 1/4" woofers, a 3/4" aluminum dome tweeter, and a carefully tuned crossover to create an engaging presentation with real scale, clarity, and everyday placement flexibility.
For listeners who want a true tower speaker without a massive footprint, the Alpha T20 offers a smart balance of output, bass weight, and musical refinement.
Highlights & Benefits
Compact tower format — gives you the scale and presence of a floorstanding speaker while fitting more easily into smaller and medium-size rooms.
Dual woofer design — two 5 1/4" woofers with dual-layer voice coils help deliver stronger bass response, higher output capability, and excellent efficiency.
Refined high-frequency performance — the 3/4" black anodized aluminum dome tweeter uses ferrofluid cooling and a neodymium magnet for clarity, sensitivity, and consistent performance.
Well-controlled crossover execution — PSB’s Acoustic Linkwitz-Riley crossover design helps maintain a smooth transition between drivers for a more cohesive soundstage.
Room-friendly bass reflex tuning — the rear port supports richer low-frequency extension and more satisfying overall weight than many compact speakers can manage.
Smart value in a real hi-fi tower — the PSB Alpha T20 Tower Floorstanding Speaker (Each) is a strong choice for music lovers who want natural sound and true stereo scale without overspending.
Technology & Design
Driver engineering focused on low distortion — the specially textured polypropylene woofer cones are designed to minimize breakup while maintaining smooth integration with the tweeter.
Advanced tweeter platform — the ferrofluid-cooled aluminum dome tweeter is matched with a neodymium magnet for improved sensitivity and better thermal stability.
Cabinet tuning with real-world placement in mind — strategically braced MDF construction, tuned wall thickness, and the rear-firing bass reflex port help control resonance while preserving strong low-end output.
In a well-matched stereo or home theater system, these towers can sound surprisingly full, open, and dynamic for their size.
