S-100 Speaker computer Speaker Power: 20 Watts RMS per channel (2 channels) Frequency Response: 40Hz ~ 20kHz Dimension (H x W x L): Products (with stand):D120*W100*H250mm*2 Driver Unit: 3 inches * 2 + 1.5 inches *2 Subwoofer Enclosure Material: Wood Signal-to-Noise Ratio (SNR): 80dB Dimension (H x W x L): Products (with stand):D120*W100*H250mm*2 Driver Unit: 3 inches * 2 + 1.5 inches *2.

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.
