PSB Alpha T20 Tower Speakers (Pair)

Signature Speaker for Both Sound and Aesthetics

The PSB T20 Tower delivers the highest quality acoustics in the new PSB Alpha Series and will easily fill any size room with lush, full-bodied sound. Leveraging the latest research in acoustic design and most advanced cabinet and driver technologies, the all-new Alpha tower adds an additional custom 5.25" woofer, while utilizing the Alpha Series' patent tweeter and crossover design, to deliver bigger and bolder sound with flawless imaging. With a center channel to match, the new T20 tower is the perfect start to creating the ultimate surround system.

Lifelike Acoustics and Detail

The T20 uses a 0.75" black anodized aluminum dome tweeter to extend the high-frequency response further than any Alpha ever before while lowering distortion to deliver a lush soundstage full of details. Unlike lesser designs at this price, all the new Alpha Series tweeters employ ferrofluid cooling to prevent dynamic compression and a neodymium magnet for high sensitivity. The tweeter’s front waveguide and its unique placement below the woofer work together to smooth the response at the crossover and perfect on and off-axis performance.

Developed for Deep, Detailed Bass

Featuring PSB’s exclusive dual 5.25" woofer connected to a dual-layer voice coil for incredible conductivity, the newest Alpha Series tower provides remarkable low-frequency response and the exceptional efficiency for a speaker at this price. Starting with a specially textured polypropylene cone that lowers distortion and reduces breakup, the woofer is perfectly matched with the tweeter at the crossover for a smooth sounding transition between high and low frequencies. It’s also backed with a rear-firing port that uses bass flex to tightly control the bass response and extend it even lower.

Reference Crossover Design

The redesigned Alpha Series tower features a new crossover that exceeds speaker standards with a innovative design that delivers the tightest control and the flattest frequency response. Developed for more than directing low and high frequencies to the individual drivers, the crossover used in the T20 employs a very advanced acoustic Butterworth low-pass filter in the cross to lower distortion and create a large, detailed soundstage for the best listening experience.

Crafted with Precision

Using a special MDF material and a unique combination of wall thickness and bracing, the Alpha T20 Tower flawlessly controls resonances while leveraging a light internal material that has been accurately positioned to reduce standing waves. The sturdy, well-constructed cabinet is finished with a high-quality wood grain vinyl and features acoustically-transparent magnetic grilles that make the speakers disappear into your décor without sonic interference.

Behind the Alpha Series

First designed and manufactured in a small Canadian town in 1991, the Alpha Series started with the simple idea of creating affordable speakers that were focused purely on performance. With passion and dedication in pursuit of a natural sounding speaker, and by leveraging decades of research conducted at the Canadian National Research Council by PSB’s founder, Paul Barton, the Alphas quickly rose to be one of the world’s most iconic speakers and are still the reference benchmark for entry-level hi-fi speakers today.

The newly designed Alphas look to continue their legacy by staying true to the original concept from the ’70s and combining it with today’s latest cutting-edge technologies. Powerful and smooth, the all-new Alpha Series has been rebuilt with enhanced custom drivers and a new crossover design that works perfectly together to deliver natural, detailed sound with precision and less distortion. In a home theatre or stereo setup, the new Alphas outperform the originals in every measurement and will bring your music and movies to life.

2022 Editors’ Choice Award - The Absolute Sound

"This is a remarkable time to be in the market for budget loudspeakers, a golden time actually. The Alpha T20 is among a select few leading the charge. It takes the concept of blue-plate, budget, modest, humble, and well, okay, cheap, and turns it on its ear. The performance and musicality it tenders will make you feel like a big spender when you gobsmack your more high-falutin’ 'Big Rig' audio friends. Finally, regarding pricing, you can’t blame PSB for boasting that when adjusted for currency inflation the new Alpha actually retails for less than the original Alpha. I’ve got news for you, PSB. You could have charged more. A speaker that just flat-out picks up your spirits."
