Logitech has expanded the G-series family of PC gaming peripherals the Logitech G51 Surround Sound Speaker System, a 5.1 speaker system featuring 360-degree surround sound with dual Matrix modes for a more immersive gaming experience.

For gamers who want to bring their games to life, the Logitech G51 Surround Sound Speaker System offers all the benefits of 360-degree surround sound - and makes it available with or without a multi-channel audio source.

With Logitech's dual Matrix technology, gamers can create a 5.1 surround-sound experience from any common
two-channel stereo source.

Nearly all digital music, and legacy games, are only primed for stereo - or two-channel - sound. Using Logitech's proprietary Matrix surround sound technology, the G51 speakers split the audio signal into six channels of sound, without degrading the audio quality.

That means, even if their game doesn't provide six-channel audio, people can enjoy it anyway. As a result, gamers can gain the competitive advantages of surround sound - first-person-shooter gamers, for example, can now hear enemies creep up behind them. Or - if they're being shot at, they'll know what direction the bullets are coming from.

The Matrix modes can be changed to suit what audio is being played. The Gaming Matrix mode boosts the rear speakers and subwoofer to provide a more intense gaming experience. And with the ported, down-firing subwoofer, explosions sound more explosive.

Music Matrix mode enhances stereo music, delivering a more natural surround sound experience through all five satellite speakers.

With 155 watts of total RMS power, the G51 speaker system is optimised to deliver high-performance audio experiences.

Responding to Logitech research, which showed the popularity of headphones and headsets with gamers, Logitech has equipped the G51 speakers with an improved control pod that includes both headphone and microphone jacks.

The control pod provides precision dual mute controls, which allows gamers to easily mute the game audio, or mute only the microphone - or both.

Independent volume controls and convenient LEDs make controlling the subwoofer, centre channel and satellite speakers simple.

Logitech has also provided the ability to mod the G51 speakers, allowing gamers to create their own artwork for the four left and right satellite speakers. And gamers can rotate the satellite stands to mount them on the wall, or clip the centre channel to the top of their LCD flat-panel monitor.

The Logitech G51 Surround Sound Speaker System is expected to be available in October for a suggested retail price of £149.99.

These speakers complete Logitech's recent G-series offerings for gamers that includes the G9 mouse and the G15 keyboard. If you've already got one, or some, it would be rude not to complete the set...
