This soundbar features S-Force PRO Front Surround for cinematic sound, X-Balanced Speaker Units for clear dialog, and a powerful wireless subwoofer for deeper bass. The soundbar couples high-quality Dolby® Digital with S-Force PRO Front Surround, our virtual surround sound technology. It puts you right at the heart of the movies you love by emulating theater-style surround sound. 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. 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 dialog. Front speakers feature an X-Balanced Speaker Unit. The unique rectangular shape of these speakers maximizes the diaphragm. It reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.
