The Sony HT-A7100B soundbar with Sub 7 subwoofer houses 9 speakers in a compact 95 cm wide unit. This audio system is designed to deliver multichannel surround sound in home living spaces, with a 100 W wireless subwoofer for the low frequencies.
The system uses 360 Spatial Sound Mapping technology, which combines physical and virtual speakers to create an extended soundfield. It supports Dolby Atmos and DTS:X formats, allowing it to process multichannel audio content. The X-Balanced speakers have a non-circular diaphragm offering a larger emitting surface than conventional drivers. The configuration includes upward-facing speakers for ceiling reflections and side-facing speakers for wall reflections, complemented by passive radiators.
HDMI 2.1 connectivity supports 4K 120 Hz HDR pass-through with VRR and ALLM compatibility for gaming. The Voice Zoom 3 feature improves dialogue clarity on BRAVIA TVs via BRAVIA Sync. Bluetooth 6 with Multi-Connect and Wi-Fi allow wireless audio streaming, with support for Hi-Res Audio, 360 Reality Audio, Spotify Connect and Apple AirPlay 2. DSEE Ultimate technology digitally processes compressed sources.
The Sub 7 subwoofer measures 35.2 x 35.8 x 13.4 cm and weighs 6.2 kg, while the main bar measures 95 x 6.4 x 12.5 cm and weighs 4.6 kg. IMAX Enhanced and Dolby Vision certification complete the audio and video processing capabilities of the system.
