Import 5.1 Computer Speakers Multimedia Speakers — Buy in Bulk from Supplier in China

The M20-5.1MKII is a 5.1 channel active multimedia speaker system employing a three-stage amplifier architecture: front-end input with digital volume control, power management circuit, and six-channel post-stage power amplification. The source indicates this revised design delivers approximately double the power handling of its predecessor, with stated frequency range of 120 Hz to 20 kHz and signal-to-noise ratio exceeding 92 dB. Total harmonic distortion is referenced at 1 kHz, though the precise percentage is truncated in the source text and should be confirmed with the supplier.

The system incorporates a remote control with digital volume adjustment for operator convenience. The amplifier topology uses what the supplier describes as a Wer circuit, likely referring to a proprietary or regionally named Class D or hybrid digital amplifier design given the efficiency gains implied by doubled power handling. The 8 ohm impedance reference and 1 kHz test frequency point suggest standardisation around consumer hi-fi measurement conventions. Typical active multimedia systems in this category employ 4-inch to 5-inch woofers in satellite channels with 1-inch soft dome tweeters, and an 8-inch or larger long-throw woofer in the subwoofer enclosure for bass management below the 120 Hz satellite crossover point.

Target applications include desktop computer gaming, home theatre PC setups, and multimedia entertainment systems where space efficiency and direct USB or analogue connection to source devices are priorities. The digital volume control suggests integration with modern source devices where analogue attenuation would introduce noise. Buyers should clarify total system power distribution across the six amplifier channels, as multimedia systems often allocate disproportionate power to the subwoofer channel. Connection protocols, input sensitivity, and whether USB audio or Bluetooth is supported are not stated and require direct supplier confirmation.
