Powerful Desktop Speakers

From PSB, a company known for its excellent lineup of speakers and headphones, the Alpha PS1 has won SoundStage Network’s “Product of the Year” and been listed among Home Theater’s “Top Picks.” These affordable powered speakers come in pairs and make a great companion for desk setups, delivering enough power to rock a small- or medium-sized room. Rated with a continuous power of 2 x 20W and a dynamic power of 2 x 40W, the high-performance amplifier is built into the left speaker, and the sound is natural with a solid bass response. Finally, the universal power supply works with any AC voltage, making the Alpha PS1 a great choice for audiophiles around the world.

The Reviews Are In

Home Theater  reviewer Darryl Wilkinson says, “The performance of the PSB Alpha PS1 speaker system was absolutely amazing, especially considering its small size and the fact that the pair costs less than $300. Whether I was listening to indie-pop (Marina & the Diamonds) or old-school rock (RUSH), the system had plenty of punch—although, as with all such diminutive speakers, it could obviously be extended by adding a powered sub.”
