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.
