PSB Alpha PS1 Details

PSB Alpha PS1 Compact Powered Speakers: Perfect for any desktop or small-room system

  • True 2-way powered loudspeakers
  • 3.5-inch metalized (TBD) polypropylene cone woofer
  • .75-inch aluminum dome tweeter
  • High efficiency 2 x 20W Power Amplifier
  • Acoustically engineered ABS cabinet with UV coating

The PSB Alpha PS1 powered speakers combine the amplifier and speaker together into a complete system solution design like no other. Finding separate amplifiers and speakers with this level of performance, at this price, would be impossible. Add in the small size, beautiful high gloss finish, and exceptional flexibility, and you have speakers that offer the ultimate value for a desktop or small room system.

Built-in amp and universal power supply, plus gorgeous and functional form factor
The Alpha PS1 features a built-in, highly efficient 2 x 20W amplifier (housed in the left speaker), a 3.5-inch metalized polypropylene cone and oversized magnet structure, plus a 3/4-inch aluminum tweeter. The PS1s are a versatile desktop solution with enough acoustic output to rock a small to medium sized room. The universal power supply works with any AC voltage, which makes it perfect for world travelers. The curvaceous, organic form is beautiful andfunctional, as it allows maximum internal volume for improved bass response.

The simple solution for great sound
Just 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 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.

Big, smooth sound from small enclosures
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 Ottawa, the 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.
