12-inch 150W powered subwoofer

This 12-inch powered subwoofer delivers 150 watts RMS and 200 watts peak output for home audio and theatre systems. It reproduces frequencies from 25 to 250 Hz with an adjustable low-pass crossover from 50 to 150 Hz. Gain and frequency controls on the panel let you match the bass level to your main speakers. The cabinet measures 17.0 by 17.3 by 17.5 inches and weighs 41.71 pounds.

Integration into a home audio system

Connect the subwoofer to a stereo or surround receiver using the line-level inputs to add dedicated low-frequency effects. The adjustable crossover and gain knobs allow you to blend the output with existing speakers without requiring external processing. Its self-contained amplifier means no separate power amp is needed, freeing rack space and reducing cable runs. The compact cube footprint fits beside furniture or in a corner.

Front-panel controls and included features

The front panel provides power on/off, gain and crossover frequency knobs for real-time tuning. These controls let you shape the bass response to suit room acoustics and speaker placement. No wireless, app control or room-correction software is included, so buyers who want automatic EQ or remote management will need a separate processor. The unit ships in black only.
