Kef - PSW 2010 Speaker

The KEF PSW 2010 is a powerful, active subwoofer from 2003, famous as the engine behind KEF's legendary KHT 2005.2 "Eitjes" home-cinema surround sets. The sub uses a sealed enclosure (closed box) with a sleek glass top plate. Thanks to the Down-Firing design the substantial 10 inch woofer radiates directly to the floor, creating an extremely tight, deep and even bass distribution throughout your listening space.

Specifications:
Output: 250 Watts RMS built-in amplifier
Frequency Response: 30 Hz – 150 Hz
Maximum SPL: 108 dB

The subwoofer works perfectly.
