Huge Bass. Compact Price

PSB redefined high performance and high value with their legendary Alpha Series speakers and the new Alpha S8 powered subwoofer continues that tradition in the all-important bass region. The new Alpha S8 offers a more compact footprint at an affordable price, while delivering big time for music and home theatre systems where bass is a must. The Alpha S8 meets this challenge by featuring a long throw 8” woofer with polypropylene cone (for fast response) in a specially-tuned, bass reflex enclosure.

Affordable Excellence With Audiophile Pedigree
PSB has been making critically-acclaimed speakers for more than 45 years and are especially famous for speakers that deliver high bang for the buck. The Alpha S8 will astound with adding lifelike realism for both music and movies to PSB speakers or any high performance speaker.

Advanced Tech in Drivers and Amplification
The Alpha S8 boasts a specialised long-throw 8” driver and efficient bass reflex enclosure for remarkable bass.The built-in high efficiency digital amplifier delivers 210W of dynamic power for unconstrained deep-bass peaks and musical accuracy. Then to go one step further, the S8 utilises digital signal processing (DSP) to allow PSB’s engineering team to maximise all aspects of performance to deliver the flattest frequency response and powerful bass extension.

Compact Cabinet Will Fit Most Anywhere
The rear-ported cabinet has an ultra-small footprint that can be sited most anywhere in the room. On the rear panel are Volume and Crossover Controls, Phase Switch, Low Level Input, AutoOn/Standby Switch, Gold-plated RCAs, USB Power Jack for wireless accessories. Supplied rubber bumpers and spikes allow for installation on hardwood or carpeted floors.


PSB Alpha Subwoofer: The S8 is in the sweet spot between where high value coexists with legendary PSB performance. Employing a specially developed long throw 8” polypropylene woofer and powerful magnet assembly, it is matched to a highly efficient 150W Power Amplifier, and placed in a well-engineered enclosure that is carefully tuned for deep, crisp bass response all the way down to an earth shaking 32Hz. The S8 is a vented, or ported, design that takes advantage of the woofers back wave to extend bass response and power output. Unusual at this low price point is the inclusion of powerful Digital Signal Processing that allows for a level of optimisation that is not otherwise possible.
