Computer Speaker Multimedia Speaker

S, high quality drivers and a decent amplifier. The m20 uses a response 3"driver and a 6"subwoofer in wood cabinets. Wood is much more effective dampening back wave transmission than plastic. The amplifier doesn't skimp on parts. The result is a surprising quality of sound for the price. The volume control is located on light cord that extends from the speaker making allowing you to make adjustments easily at any time.

Wer amplifier circuit, which consists of three components; front end input circuit with digital volume control, power control circuit, and six-channel post-stage power amplifier circuit. The result is a system with almost twice as much power handling as the previous revision with improved dynamic sound and deep powerful bass. Included in the revisions was also a convenient remote with digital volume control for easy operation. The m20-5.1mkii provides
