PSB SubSeries 125 Subwoofer

PSB SubSeries 125

PSB Speakers announced the compact and affordable SubSeries 125 home theater bass reflex subwoofer, which features a 125-watt amplifier and 8-inch woofer with polypropylene cone. It replaces the SubSeries 1. Power has been increased to handle 160 Watts of Dynamic power and 320 Watts of Peak Dynamic power in a small package only 9 5/8 inches wide by 14 1/8 inches high by 15 5/8 inches deep and weighing 24 pounds.

The SubSeries 125 employs an 8″ woofer with polypropylene cone and an oversized rubber surround that permits very long cone excursion. The slotted port design yields high output with very low port noise and bass extension is only 3dB down at 35Hz, with useful low frequency output down to 31Hz.

The SubSeries 125 will deliver lower, louder, and more musically natural bass. And despite its compact and unobtrusive appearance, SubSeries 125 provides the kind of high-impact performance associated with many bigger and more expensive subwoofers.

Coaxing this high level of performance from such a compact subwoofer is an engineering feat, however 40 years of experience along with a deep working knowledge of acoustics gives PSB Speakers a clear advantage. Like all PSB Speakers, final voicing is performed by Paul Barton at Canada’s famed National Research Council. PSB’s research has revealed how listener preferences can be integrated into a wide range of speaker designs for many different applications, yet all featuring consistent sound quality that is natural and lifelike.


  • 125-watt continuous amplifier delivers dynamic peak power of 320-watt
  • 8-inch woofer with Polypropylene cone
  • Front mounted volume and crossover controls for easy access

  • Energy-saving 0.5W standby power consumption.
