  • The Alpha PS1 Powered Speaker is engineered for the true-to-nature sound for which PSB is known. Many small speakers employ tricks like exaggerating the treble or falsely boosting bass to overcome limitations and poor performance, but not so with the Alpha PS1. Using sound research and exhaustive testing at Canada's National Research Council in the nation's capital of Ottawa, our PSB team has designed the Alpha PS1 with extremely smooth and refined sound. You'll be pleasantly surprised by its output capability and solid tuneful bass response that belies the Alpha PS1's diminutive size. The response off to the sides of the speaker has the same smooth response as the sound directly in front, making the Alpha PS1s acoustically 'disappear' by projecting a large and exquisitely detailed sound image—a PSB performance hallmark. This is no ordinary computer speaker!

    Simply plug your computer, game console, tablet or smart mobile device into the Alpha PS1 and you have a complete sound system—one with a high-end audio pedigree. For the ultimate in gaming excitement and dramatic home theatre effects, an optional SubSeries 100 powered subwoofer can easily be added by connecting to the convenient subwoofer output. The volume control will now adjust the Alpha PS1 speakers and the subwoofer together in perfect synchronization. If you crave a sonic boost for your TV, computer, CD, DVD or Blu-ray player or any other device, the Alpha PS1 won't disappoint. You can even go wireless by using Apple's AirPlay ecosystem and just connecting an Airport Express to the Alpha PS1.

    Sporting a 3.5" metalized polypropylene cone and oversized magnet structure, the Alpha PS1 boasts a ¾" aluminium tweeter. The Alpha PS1 also includes a highly efficient 2 x 20W power amplifier. The universal power supply works with any AC voltage making it convenient for world travellers. Its curvaceous organic form is functional as well as beautiful, allowing maximum internal volume for good bass response.
