Sony has launched a new model into its Bravia theatre "invisible home cinema" products that offer surround sound hidden in a TV stand.

The new RHT-G500, which fits into the line-up below the existing RHT-G900 and G1500, is designed for use with 32 to 40-inch TVs.

The RHT-G500 uses a 3.1-channel sound system, with centre, left and right speakers and subwoofer built into the TV stand.

Using S-Force PRO Front Surround technology, Sony says the RHT-G500 "creates a soundfield that not only fills the room, but also envelops listeners in breathtaking surround sound effects".

The RHT-G500 has three HDMI inputs and a monitor output, Bravia sync and a Sony digital media port for connecting portable players and Bluetooth devices.

Complete with a remote control, pricing and availability has yet to be confirmed.
