PSB Unveils Two High-Performance Alpha DSP Controlled Powered Subwoofers

PSB Speakers announced two new affordable subwoofers for high-quality music and movie listening. The Alpha S10 ($549 U.S. MSRP) and the Alpha S8 ($449 U.S.) follow the successful launch of four Alpha models earlier this year. The new Alpha DSP Controlled Powered Subwoofers are both bass reflex designs with rear port, featuring the same 150 Watts continuous power amplifier in a compact cabinet, using drivers with polypropylene cones and rubber surrounds. The S10 and S8 will be introduced at Rocky Mountain Audio Fest (RMAF) 2019 and will be available October 2019.

The two new subwoofers offer compact, high-performance versatility for home theatre and music applications where effective deep-bass reproduction is a must. The Alpha S10 and Alpha S8 meet the challenge with specialized long-throw drivers and efficient, bass-extending bass reflex enclosures. Both models employ digital signal processing (DSP) to allow PSB’s engineering team to maximize all aspects of performance to deliver the flattest frequency response and powerful bass extension. Both models use the same 150 Watt high-efficiency digital amplifier and variable crossover from 50-150Hz.

Both subs are built in compact cabinets of black woodgrain and the S10 features a 10” woofer with polypropylene cone and rubber surround while the Alpha S8 sports an 8” woofer. Other than woofer size, the two new PSB subs have similar feature sets. On the rear panel, there are Volume and Crossover Controls, Phase Switch, Low-Level Input, Auto On/Standby switches, gold-plated RCAs, and a USB Power Jack for RT100 wireless accessory. The supplied rubber bumpers and spikes allow for installation on hardwood or carpeted floors.

Like all PSB speakers, final voicing is performed by Founder and Chief Designer, Paul Barton, at Canada’s famed National Research Council. “Alpha products enjoy a long and successful history for PSB and have developed a reputation for outsized performance at their given price points,” comments Paul Barton. “Earlier this year, we launched a new range of four Alpha models which were the first ones in nearly twenty years. The new Alphas have been enthusiastically received with requests for subs to complement them. Thought they do that quite well, the S10 and S8 are equally well suited for use with any quality speaker for music or movies.”

The new PSB Alpha Subs will be on display at the Rocky Mountain Audio Fest, September 5-8, in Room 6117 at the Gaylord Rockies Convention Center. Lenbrook’s other brands, NAD and Bluesound, along with DALI, will also be on display.
