The verdict
The Quad suits people who want immersive Dolby Atmos without a soundbar under the TV, and What Hi-Fi rates its features and convenience highly. Its high price and thin bass mean most buyers should budget for one of Sony's optional subwoofers, and it has no physical center channel unless a compatible Sony TV takes that role. Buyers who need a stronger bass foundation at a lower total cost should compare full soundbar packages.
The BRAVIA Theater Quad (HT-A9M2, sold as the Bravia Theatre Quad in the UK) is a 4.0.4-channel wireless surround system made up of four slim speakers with 16 drivers in total, plus a small control box with HDMI eARC and one HDMI input. Sony's 360 Spatial Sound Mapping creates phantom speakers around the room. Reviewers praise its clear, spacious sound and simple setup, but it is expensive, includes no subwoofer, and What Hi-Fi says its bass lacks weight.

Likes the clarity, spatial effects and easy setup, and says it improves on the older HT-A9 in many ways, but finds the bass light on weight and depth and the system hard to recommend wholeheartedly given the cost of adding a subwoofer.
Read the originalCalls it a virtual-surround success with compact active speakers, convincing phantom speaker placement and strong stereo upscaling, while noting the lack of a subwoofer, a control box with limited inputs and the need for plenty of power outlets.
Read the originalAfter about a month of use, the writer praises the audio but dislikes the missing physical center channel, says dialogue can strain in busy scenes, and calls the Bravia app buggy, concluding it best suits buyers who do not want a soundbar.
Read the originalNo. It consists of four wireless speakers and a control box. Sony sells optional wireless subwoofers such as the SA-SW3 and SA-SW5, and What Hi-Fi says the system really needs one for bass depth.
Not a physical one. It uses 360 Spatial Sound Mapping to simulate one, and compatible Sony TVs with an S-Center Out terminal can act as the center channel, per Tom's Guide.
Through its control box, which has an HDMI eARC output to the TV and one HDMI input for another source. The four speakers connect wirelessly but each needs a power socket.
Yes. It supports Dolby Atmos and DTS:X as well as Sony's 360 Reality Audio, per What Hi-Fi and SoundGuys.
