Product Information

A new frontier of surround sound

Immerse yourself in a multi-dimensional audio experience with the HT-A9 Home Theater System. Unique 360 Spatial Sound Mapping technology calibrates sound to your room for an environment that seems to expand beyond the walls.

360 Spatial Sound experience, like you're in the scene

Surrounded on all sides by multiple phantom speakers within an optimized sound field, you’ll hear every flap of wing and gust of wind with incredible intensity. It’s like you and your living room are inside the movie.

Flexible layout for any situation

Reduce clutter and enjoy a simple setup without a need for extra cables. HT-A9’s speakers wirelessly connect to the control box, allowing you to place them anywhere in the room. Sound Field Optimization allows you to have the speakers at different heights and distances and will measure the position of each speaker to create the best sound for your room.

Connect wirelessly 

Place the control box near the TV and link up via HDMI. The four speakers connect wirelessly to the control box so there are no cables across your living space.

Sound Field Optimization

Activate Sound Field Optimization any time by performing Easy Setup from the home menu on the TV screen. The HT-A9 Home Theater System intelligently measures the distance between speakers and ceiling for smart and easy setup.

Not working well with my A80J TV
Most of the time my TV cannot detect the HTA9 or not sound at all. Have to restart my TV to get it work again everything. Also HTA9 sound cut off from time to time. Poor execution else is a very nice sound system. Surprise that not working well with Sony A80J TV.

Look mom no center channel, lol .
I am extremely happy with the HT-A9. The sound stage is wonderful; and before you ask, yes you need to purchase the sub, there's no way around it. If you can get the HT-A9 home you will enjoy it.

Sounds really great.
It’s been a week I have the hta9 with sw5 sub. They both sound incredibly good. No connection issue at all. Using a80j as center channel and I can hear any dialogue clearly. Sound coming from all directions fills my living room.

The best HT system than any other soundbar
I bought 2 months ago. Setup was super simple. Audio skipping issue noticeable on first day, but manage to solve after relocate speaker & recalibration. But after sometimes the issue cameback again, I need to reset the whole set again. Hope Sony aware on this since not only me facing this. Expecting software update solution. The positive is new level of experience in surround. All 4 speakers equally powerful, unlike soundbar providing small low power rear surround speakers. Bass a bit lack, definitely need additional sub. I have ordered SW5 but haven't received yet. Overall HT-A9 system worth buying if everything work smooth without audio skips due to RF signal.

Game changing sound and simplicity
I chose the HT-A9 after extensive testing of Sonos Arc, Bose 900, Samsung Q950A, and Sony HT7000 systems in the same room with the same input sources. The simplicity of design, integration with Sony TVs, homogeneous immersive sound with excellent Atmos performance were the top reasons for the choice. The lack of a sound bar helps the listeners focus on the audio content and not on the specific source of sound channel. The phantom center channel eliminated the need to connect the audio cable back to the TV separately. Few expert reviewers do not turn on all sound optimization features which makes them miss out on things like Immersive audio enhancement which is the key difference this system has vs others. I am not an expert or paid reviewer but a life long Sony fan. Bought multiple Sony TVs so far and Sony has not given a reason to switch. Highly recommended if you want to experience the next level of immersive audio and 360 reality sound.

Poor quality control
Got delivery after 3 months of full payment. Sounded great, till it did. One of the speakers died in a week. Service centre not responding due to local holidays. Apparently there is a long wait for replacement due to supply problems internationally, but I need to test this. Very disappointed by the poor quality control as my set is not the only one with this issue, if you read the forums. I’m scared to even try and buy the additional subwoofer if the quality issues are going to persist across the line. Luckily there are no supplies for the next couple of months, giving me an opportunity to see how Sony responds to this issue.

Excellent sound
It does what is says! Once it goes through its set up the sound quality is fantastic! Especially when paired with the TV. Everything connects and it accepts all forms of sound forms. Looks clean and sharp!

90% there - awesome product that could be perfect
The HT-A9 is a fantastic system. I’ve had it a few months now and am more sad overall.
A few improvements could be made however that would make it a truly must own product.

1, The height channels could have more oomph we have a relatively low ceiling and some of the effects come off as muddled, we’ve tried the immersive sound, dts x and dolby virtualizer- all sound quite similar although the dts x is the clearest and has the best surround sound effects and volume overall.

2, There should be an option to add 2 more speakers to the set up retroactively making 6 Ht-A9s and a tv center channel this would create a soundstage that could be even more fine tuned.

3, I own a Sony KD85 85inch 4K tv from July 2020 which new by any standards and yet I cannot use it as the center channel, this is particularly frustrating as it means I’ve just spent thousands of pounds on a set and yet cannot use it with the latest Sony theatre system. I’m sure this could be updated to be used as a centre channel via a firmware update to then connect to the speakers wirelessly via blutooth. 

These minor improvements would make a huge difference overall.

I do plan on getting a new set but am waiting for the QD OLED in a 97 inch of which you announced you currently only produce at a maximum size of 65 inch.
