  • Product Description

    The PSB T20 Tower delivers the highest quality acoustics in the new 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.

    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.

    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.
