Sony Introduces HT-S400 Soundbar and Wireless Subwoofer

The 2.1-channel system uses Sony’s virtual surround sound technology S-Force PRO Front Surround.

Sony has announced the HT-S400 2.1-channel soundbar, which includes its S-Force PRO Front Surround technology, clear dialog features, and 330-watt total power output.

The HT-S400 lets users hear sound from all around thanks to high-quality Dolby Digital with Sony’s own virtual surround sound technology S-Force PRO Front Surround. By using front speakers only, Sony’s digital soundfield processing technology virtually reproduces the surround soundfield.

The front speakers include an X-Balanced Speaker Unit, which features a rectangular shape that maximizes the diaphragm. It also reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.

The Separated Notch Edge on the X-Balanced Speaker Unit improves vertical amplitude symmetry, which is essential for clear sound quality. It achieves this by using strategically placed cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm. With these two features, customers will never miss a word during a high-octane action sequence or subtle, tense moment of conversation.

The soundbar comes with a wireless subwoofer with a 160mm speaker unit to deliver a deeper, richer bass sound.

Connecting the HT-S400 to a Sony BRAVIA TV is easy thanks to an integrated user interface. The soundbar settings automatically appear on the BRAVIA TV’s Quick Settings menu for control of sound settings and volume with BRAVIA’s remote control.

To minimize cable clutter, the HT-S400 soundbar has been built to receive audio wirelessly from a BRAVIA TV for a wireless connection.

The soundbar has been designed to deliver an intuitive user experience thanks to its simple remote control that combines a comfortable hand-fit design with easy operation. It also provides easy access to Voice mode for clearer dialog and Night mode for when users want to watch TV without waking the house.

The ease of use is also found through the OLED display window on the soundbar, which offers at-a-glance status information on remote control functions, including input source, volume, and sound settings.

The HT-S400 has a suggested retail price of $299.99 and will be available to order in April 2022 at authorized dealers.
