The KS220 subwoofer is designed for exceptional performance and value. The woofer is driven with a high efficiency 110W class A/B amplifier.
FEATURES:
- The KS220 subwoofer was designed to deliver exceptional performance and value in a compact package. It features a 8" extra-long excursion woofer with high BL motor.
- The bass reflex enclosure with flared port ensures extended bass response and high acoustic efficiency.
- The woofer is driven with a high efficiency 110W class A/B amplifier. The integral rear-mounted amplifier includes level, phase (continuously variable 0-180°), and crossover control to contour the subwoofer’s output to blend with virtually all loudspeakers and room environments.
- The integral low pass crossover network is continuously-variable from 40Hz to 128Hz and can be bypassed if it is preferable to use an external crossover located in an outboard receiver or processor.
- The KS220 incorporates a defeatable signal-sensing circuit that automatically powers up the amplifier when a signal is detected.
- A double-insulated isolated-ground electrical supply prevents electrical ground loops and reduces the noise floor of the entire audio system.
- Transferable Warranty: 5 Year Amplifier / 25 Year Driver
