Sony Bravia Theatre Quad Review

Sony’s “alternative to a soundbar” concept is back — and upgraded.

A couple years ago, Sony launched the HT-A9: a four-speaker wireless home theater system that delivered Dolby Atmos without using a traditional soundbar. Now there’s a new version, renamed and redesigned as the Bravia Theatre Quad (model HT-A9M2).

It’s still not a soundbar. Instead, it’s four individual active speakers that connect wirelessly through a control hub, each speaker handling not just left/right audio but also height and surround channels for Atmos and DTS:X.

For this review, we paired Theatre Quad with Sony’s SA-SW5 subwoofer. Important note: the subwoofer is sold separately.

Core Specs: Sony Bravia Theatre Quad (HT-A9M2)

• System type: 4 wireless satellite speakers + control hub
• Channels: 4.0.4 (16 total drivers across the four speakers)
• Formats: Dolby Atmos, DTS:X, plus legacy Dolby/DTS formats, and Sony’s 360 audio format
• HDMI: HDMI eARC/ARC to TV, plus one HDMI input with HDMI 2.1 passthrough (4K120, Dolby Vision, VRR)
• Other ports: Ethernet, S-Center Out (for compatible Sony TVs), optical SPDIF option
• Wireless: Wi-Fi 5, Bluetooth, AirPlay 2, Spotify Connect
• Box includes: control unit, four speakers, remote, HDMI cable, power cables, quick-start docs

Chromecast streaming is notably gone this generation (it was supported on the original HT-A9).

Design & First Impressions

The original HT-A9 used rounded, cylindrical speakers that looked a bit bulky. The new Theatre Quad turns those into slimmer, square-ish panels. Each speaker is now a flat, fabric-wrapped unit with a cleaner living-room aesthetic. You can put them on the included feet or mount them on the wall — there are mounting points on the back.

Hardware changes:

• Each speaker went from 3 drivers to 4 drivers.
• That brings the total system to 16 drivers, arranged to fire sound forward, upward, and outward so you get Atmos height and surround without rear wiring.
• The front-facing section is now a true 3-way design, which gives you better midrange detail and clarity than the old two-way layout in HT-A9.
• There’s also a dedicated up-firing driver in each unit for overhead effects.

In short: cleaner look, denser driver setup, more flexibility.

Build quality feels premium. The new flat form factor should blend in more easily than the old “small white cylinders” aesthetic. The power cables are gray and reasonably long, and since each speaker is active (amplified), each one just needs a power outlet — no speaker wire runs between them.

One caveat: the SA-SW5 subwoofer doesn’t match this new minimalist aesthetic at all. It’s big, boxy, and visually louder than the Quad speakers. You’re going to see it in your room.

Control Box & Connectivity

All four speakers talk wirelessly to a small “brain,” the control hub. That hub then connects to your TV through HDMI ARC/eARC (required for Dolby Atmos from TV apps). There’s also optical if you’re using an older TV, though that won’t carry Atmos.

On the back of the box:

• HDMI eARC/ARC out to the TV
• A passthrough HDMI input with HDMI 2.1 support, including 4K at 120Hz, VRR, and Dolby Vision
• Ethernet
• S-Center Out (more on that below)

That HDMI input matters. If your TV only has one eARC port and you’re “using it up” with this system, you can still feed a console into the Quad box and let it pass video through to the TV with the latest gaming features intact.

The box also has a front display that shows input, volume, etc. One thing we didn’t love: it has an internal fan. The fan noise isn’t a high-pitched whine, but more of a low hum, and we could clearly hear it at around 3.5 meters away during quiet scenes. And because any fan can get noisier with wear over time, that’s something to keep in mind.

Center channel integration with Sony TVs

If you’re using a newer Sony Bravia TV (like the Bravia 9 / XR90 we tested with), you can use the TV itself as the system’s “center speaker.” The control box has an S-Center output to feed the TV’s speaker hardware directly.

In theory, that anchors dialogue to the screen more convincingly. In practice, it mostly works — but we did notice that sometimes the Theatre Quad box and the TV didn’t perfectly agree on whether “Acoustic Center Sync” was currently enabled. Once you set it and walk away, most people won’t keep toggling it, so this is more a reviewer pain point than a dealbreaker.

If you’re not using a compatible Sony TV, Theatre Quad will emulate a center channel virtually.

Setup Experience

Setup is handled primarily through Sony’s Bravia Connect app. You use the app to:

• Pair the speakers and sub
• Calibrate timing and levels for your seating position
• Run room correction so the system knows how far each speaker is from you

Volume can be controlled through HDMI-CEC, so you don’t technically need to use Sony’s own remote day-to-day. Your TV remote (or even a streaming box remote) can raise/lower volume just like a soundbar.

The app is definitely an improvement over the original HT-A9’s setup flow, which required doing most of the configuration through on-screen menus via HDMI. That said, the app could occasionally lag while detecting the system, and making certain tweaks sometimes caused audio to briefly drop out during calibration.

For streaming audio, you’ve got AirPlay 2, Bluetooth, and Spotify Connect. Chromecast built-in, though, is missing in this generation.

Listening Test: Music

Let’s start with music, because this is where most soundbars fall apart — and where Quad actually shines.

Even with the speakers placed relatively close to the TV, stereo imaging is far wider and more convincing than what you get from a single long soundbar under the screen. The system can fill a mid-sized living room with ease and has more headroom than a typical TV audio setup.

Vocals and the midrange sit forward and clear. The new 3-way driver design in each satellite really helps here: you get better instrument separation and more natural voicing than on the original HT-A9.

There are two caveats, though:

1. Price. By the time you’re looking at Theatre Quad plus the SA-SW5 sub, you’re into serious money. At that level, you could also walk into a decent hi-fi shop and buy a traditional stereo amp + bookshelf speakers and get gorgeous 2-channel music. So if music is your #1 use case, you should compare those paths honestly.
2. Bass. Without a sub, Theatre Quad just doesn’t deliver satisfying low-end weight. It’s not a “turn it to max and rattle the windows” situation — even at normal listening levels, the system just sounds a bit thin if you don’t add the subwoofer. For movies it matters even more (we’ll get to that in a second), but it’s noticeable in music too. In other words: budget for the sub.

On the upside, the four-speaker layout easily beats most premium soundbars for stereo width and clarity at moderate volumes. Music actually sounds like it’s coming from a space instead of a bar sitting under the TV.

Spatial audio / Dolby Atmos music is a maybe-soon story. Apple has announced plans to enable Dolby Atmos over AirPlay 2 on third-party hardware, but during our test we couldn’t get spatial tracks from Apple Music in Atmos through AirPlay yet. If and when that lands broadly, this system could become a pretty cool “living room listening rig” for immersive music.

Bottom line for music:

• Way better soundstage than a single soundbar
• Clean midrange and vocals
• Needs the subwoofer for proper bass
• Price puts it up against real hi-fi gear

Listening Test: Movies, TV, and Games

Here’s where things get interesting — and a little more mixed.

Dialogue clarity is excellent. Voices in movies and shows are intelligible and not boxy or muffled. High-volume action (glass shatters, gunfire, explosions) can start to sound a little sharp at the top end if you’re really pushing it, but overall the system has good detail retrieval.

Surround and height effects are convincing for a wireless system: you get a decent sense of sound coming from the sides, behind, and above. Like all “virtual height” and bounce-based Atmos systems, it can’t match the precision of in-ceiling speakers, but for something this living-room-friendly, the wraparound effect is surprisingly immersive.

However — and this is the main weakness — the center image can be finicky.

Because Quad doesn’t have a physical dedicated center speaker in the middle, it has to create a phantom center by blending the front-left and front-right speakers (or relying partly on the TV if you’re using Acoustic Center Sync with a Bravia TV).

In practice:

• If you’re sitting dead center, you get well-anchored dialogue.
• If you slide one seat over, you start to notice that voices feel like they’re favoring the nearer speaker instead of coming from the middle of the screen.

Using a compatible Sony TV as the center channel helps, and with the Bravia 9 (XR90) we tested, it definitely improved “voice comes from the screen” realism. But that fix isn’t perfect, and it depends on you owning a recent Sony TV.

Also: you absolutely, absolutely want the subwoofer for movies and games. Without it, big cinematic moments feel flat. With the SA-SW5 sub, you finally get the low-end impact and cinematic rumble that Atmos mixes are built around.

Gaming

For console gamers, there’s good news:

• The HDMI passthrough on the control box supports 4K at 120Hz, VRR, and Dolby Vision.
• We had no issues getting Dolby Atmos game audio from a PS5.
• If your TV’s eARC port is “occupied” by the Quad box, you can run your console through the Quad’s HDMI input and still keep all the next-gen gaming features.

One heads-up: inserting any extra box in the HDMI chain usually means slightly longer black-screen pauses when switching between SDR and HDR modes. That matters less with a console (which often stays in HDR once you’re in a modern game) and more with streaming boxes that flip in and out of HDR constantly. So ideally, plug your console into the Quad box, not your streaming stick.

So… Quad or a Premium Soundbar?

People keep asking: “Should I get the Theatre Quad, or should I just buy a high-end soundbar + sub + surrounds?”

Our honest take:

• For music and wide stereo imaging, Theatre Quad beats most all-in-one soundbar packages at similar money. The four discrete speakers simply throw sound into the room in a more open way.
• For movies/TV dialogue, a traditional soundbar with a true center channel can sometimes feel more locked to the screen, especially off-axis.
• Aesthetics matter too. Quad’s satellites look clean and modern. The SA-SW5 sub does not, and it’s not subtle. Some folks will be fine with that, some absolutely won’t.

Also, at this price level, you’re not far from the “what if I just buy a receiver and real speakers?” conversation. Quad’s counterargument is simplicity: no speaker wires between rears, auto calibration in an app, easy Atmos from any TV with eARC, and HDMI 2.1 passthrough for your console. It’s basically a living-room-friendly Atmos rig for people who don’t want to build a traditional AVR setup.

Final Verdict

The Sony Bravia Theatre Quad is basically the evolution of the HT-A9: sleeker design, refined driver layout, better app-based setup, and the same core idea — true multi-speaker Atmos without installing a full receiver-based surround system.

What it does well:

• Much wider, fuller music playback than typical soundbars
• Clear dialogue and solid surround presence for movies and shows
• HDMI 2.1 passthrough with 4K120 and VRR for gamers
• Wireless linking between speakers, plus app-guided room tuning
• Compatibility with Sony TVs as a pseudo-center channel
• Supports both Dolby Atmos and DTS:X, which many competitors still don’t handle equally well

Where it falls short:

• No meaningful low-end without adding the (visually clunky) subwoofer
• Off-axis dialogue focus isn’t as convincing as a proper physical center speaker
• The control box has an audible fan
• Chromecast support is gone
• The price has crept up

Last year, with the original HT-A9 concept, the unusual design and “no soundbar needed” approach felt like a fresh, pricey-but-justifiable solution. Now, with the higher price of the Theatre Quad, the value is harder to defend unless you specifically want this style of wireless multi-speaker Atmos system.

So here’s the bottom line:

• If you want a traditional home theater-style center channel and don’t want to think about calibration quirks: you may still prefer a top-tier soundbar + sub + surrounds, or even an entry-level AVR setup.
• If you care almost as much about music as you do about movies, want Atmos, want wireless simplicity, and are okay budgeting for the subwoofer — the Bravia Theatre Quad is still one of the most unique, living-room-friendly systems you can buy.

It just no longer feels like an automatic “must-buy” at its new price, so we’re not giving it an award this time.
