SKU SUBSERIES300 Categories , Brand:

PSB’s 300-watt, 12″ SubSeries 300 is the first in a new line of subwoofer designs to be powered by NAD Electronics’ sophisticated, high efficiency amplifier. NAD is renown in audiophile circles for its superb sounding and highly efficient amplification, and the NAD circuitry in the 300 is worthy of NAD’s name and reputation.

The SubSeries 300 also features trickle-down technology from PSB’s award-winning SubSeries 500 flagship, including the company’s exclusive “smart bass” limiting circuitry. As a result, the SubSeries 300 offers a winning combination of power, high impact bass, and musicality.
