Surround made simple

Using front speakers only, Sony’s unique digital sound field processing technology virtually reproduces the surround sound field, with audio coming at you from both sides. You can enjoy rich, cinematic surround sound.

Enjoy clear dialogue and powerful sound

Powerful speakers work together to deliver wide-ranging sound throughout your room, with technologies such as the X-Balanced Speaker Unit and Separated Notch Edge on the speaker unit helping to enhance vocal clarity. So whether you’re watching movies or TV, you won’t miss a word of dialogue.

X-Balanced Speaker Unit

Front speakers feature an X-Balanced Speaker Unit. The unique rectangular shape of these speakers maximises the diaphragm. It reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.

Separated Notch Edge

The Separated Notch Edge on the X-Balanced Speaker Unit improves vertical amplitude symmetry, an essential for clear sound quality. It achieves this using strategically placed cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.
