Pioneer Electronics has unveiled a 5.1 surround sound system with all the trimmings, officially licensed for the Xbox 360.

The HTS-GS1 features compact speakers for smaller rooms and an integrated 6-channel receiver subwoofer which, we're promised, delivers 600 watts total RMS system power an 155 watts FTC system power. The receiver subwoofer offers connectivity with all five-speaker connections, three digital inputs (1 coaxial, 2 optical), an analogue input, tuner, and control ports located at the back of the subwoofer. The receiver subwoofer can also be monitored with a separate display that is included in the package.

The system also features what Pioneer calls the "multi-channel acoustic calibration system" (MCACC), which is a self calibrating mechanism for the speakers, allowing them to automatically adjust each speaker for distance, volume and room equalization. The system also includes the usual gamut of presets and front stage surround, which simulates surround sound even while all the speakers are positioned in front of the listener.

The HTS-GS1 will be available in June for $500 in the US. European release plans have not yet been announced.
