Overview
Bass comes from a separate wireless subwoofer in Sony's HT-S400, a 2.1 channel soundbar system rated at 330 watts total, finished in black with wall-mount support for the bar.
Pairing a soundbar with a dedicated subwoofer, the HT-S400 targets buyers who want a step up in bass response from a TV's built-in speakers without moving to a full multi-channel surround system. The wireless link between bar and sub avoids running a cable between them.
- 2.1 channel soundbar with wireless subwoofer
- 330W power
- Wall mount compatible
- 16.1 lb, black
Who it's for
This suits anyone upgrading TV audio for movies and general viewing who wants added bass without installing rear or height speakers. It's not built for home theater setups wanting discrete surround channels beyond front and low frequency.
Pros and cons
- Wireless subwoofer for added bass
- 330W combined output
- Wall mountable soundbar
- 2.1 channel only, no dedicated surround or rear channels
- No HDMI or optical input listed in specs
Performance notes
The 330 watt total output splits across the 2.1 configuration, with the wireless subwoofer handling low frequency response separately from the bar's stereo channels. Wireless connectivity links the two pieces, and the bar supports wall mounting for a cleaner setup under a TV.
