The Alpha PS1 is a true two-way powered speaker with a built-in high-performance amplifier that can easily be set up on any desktop and provide detailed full-range sound for your computer or laptop. Starting with the Alpha’s original concept of great sound for an affordable price, the Alpha PS1 is equipped with a 3½” (90mm) metalized polypropylene cone and a ¾” (19mm) aluminium tweeter powered by a high-performance 20 watt amplifier to give you enough acoustic output to rock a small to medium-sized room. Add in its small size, beautiful high gloss finish and exceptional flexibility, and its the perfect speaker to take your desktop system to the next level.

You can create a complete audiophile-quality system by simply plugging the Alpha PS1s into your computer or laptop, without any other stereo components necessary. For the ultimate gaming and entertainment experience, connect the PSB SubSeries 100 to the PS1’s rear-mounted subwoofer output and use the sub’s adjustable crossover and phase controls for fine-tuning and seamless 2.1 imaging. The rear USB power port can charge many of your devices or you can connect a Bluetooth USB adapter and stream music wirelessly.

Compact and beautifully finished in a high gloss piano black, the Alpha PS1 aren’t just for playing games and watching movies–it’s to experience to the fullest. Sitting down you’ll hear a soundstage that seems to extend way beyond the speakers and deeper, more detailed thanks to a tuned port tube and advanced digital audio processing inside the speaker.

  • 3½” (90mm) Black metalized polypropylene midbass woofer

  • ¾” (19mm) Aluminium ferrofluid-cooled tweeter with front waveguide

SubSeries 100:

Mighty small, mighty powerful
Its computer-optimized 5¼” (135mm) long-throw woofer is perfectly matched with an internal Class D amplifier to squeeze out the best bass extension and dynamic range without distortion. The polypropylene woofer is carefully placed and acoustically suspended inside the resonance-free enclosure for deeper, more detailed bass from a driver of its size. Couple this design with an innovative filter pole shifting technique used to deliver more punch, PSB’s smallest sized subwoofer is not to be underestimated when it comes to performance.

PSB leaves no stone unturned when it comes to the SubSeries 100 and its features, like adjustable volume and controls for setting the crossover frequency and inverting the phase to seamlessly integrate with smaller desktop systems and satellite speakers. When combined with the Alpha PS1 to create a small yet powerful full-range system, there are crossover controls on the rear panel with special markings that indicate the optimal settings for the best possible imaging.

Versatility matters
A perfect subwoofer for any space, the SubSeries 100 is less than half a square foot in size and can be placed virtually anywhere. No matter if it’s tucked under a desk or placed inside a cabinet or bookcase, the SubSeries 100 can connect directly to your speakers and provide a floor-shaking sound experience. If more oomph is what you crave, add a second sub to double the low frequencies in the room, as two smaller subwoofers can offer a smoother, more even response in almost all rooms.
