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.

Bad out of the box
ARC/eARC interface defective. Several hours of troubleshooting over several days with Sony technicians, narrowed the problem to the.HT-A9 controller. Sony wanted me to send it in to one of their authorized dealers for repair. Instead, I opted to exchange it with Amazon. The new system worked perfectly. Big pain.

Amazing Atmos affect and stunning sound quality.
Bought the HT A9 as a treat to myself. Ater doing a bit of homework the reviews seemed to good to be true as all reviews were positive. Set up took minutes and everything seamlessly connected. Movies and music have a whole new life and 360 audio is just brilliant. The sound bubble is also phenomenal.

Soundly Brilliant
I have been up grading through the years from stereo to 5.1 to 7.1 and now spatial sound this has got to be the best,4 speakers and little box of tricks that give original movie sound and all setup with ease.
Sony has cornered the market and I am over the moon with the result. Highly recommended

Sub woofer not included
Sub woofer is an optional extra. Disappointing, given the c £1800 price a Samsung sub, but not Bluetooth compatible with the Sony unit.

New surround system & should have done it sooner
I have hesitated over this purchase as I had hoped to see it instore for a demo but have struggled to find this anywhere even on display. However, after reading all the reviews & spec I decided to change my existing Sony sound system for this & the added sa-sw5 subwoofer. I am delighted with the product & sound generated. It was well worth adding the sa-sw5 & my music listening is so enhanced, the availability of tracks for playing on the 360 Spatial audio format is good, the control buttons are easy to identify & allow me to increase rear speaker & bass level which I have found great for our living space. The sound within the room is way beyond the clarity at lower level than I expected after my previous system. Will continue to explore various modes & options available from the system but so far after first 2 weeks I am really pleased with this system. The pairing to my Sony TV was so easy & I am not a technical expert so go ahead if you are thinking of buying this system.
I agree that cable length for speakers could be improved, or Sony could offer them as an extra over option to buy at same time. The colour of the speakers is ok but again a small negative would be options on colour would have suited my exiting decor.
Could Sony not offer a discount if we traded in our old equipment? Sorry if this is already an option I have never come across it with Sony but have used it for other electronic suppliers.
The technical support from Sony prior to making the purchase was superb so well done, they are a credit to your company.

Amazing sound but disappointing connection
I am amazed by the sound quality of the system. Not only do they produce great sound, they also look neat and more subtle compared to a soundbar. However, I have many issues with the sound suddenly dropping out or the system not producing sound upon exiting stand-by. I have tried all the recommended rectifications issued by Sony and had the system replaced by a new set under warranty but the second one also has issues, perhaps a bit less compared to the first set, but this shouldn't be the case for such an expensive sound system. Nonetheless, I am still happy with the purchase, especially when paired with the SA-SW5 subwoofer (the bass it can produce is astounding!).

You get what you pay for!
A Christmas treat for myself and what a treat. A couple blips setting up, but I'm no Bill Gates! Once set up WOW . And the guys from Sony Leeds most helpful and patient. See for yourself.

Seems Overrated Everywhere
I've been waiting to get my hands on this for over a year. Massive stock shortages as well as the steep price have held me back.
Every single review and video though rates this as just about the best you can buy.
I'm not so sure. First real world problem is speaker range. You're supposed to be able to put the speakers anywhere but I had terrible trouble with the front dropping signals. I had to move it closer to the TV than I wanted.
The control box doesn't like being in a cupboard either as that will make the speakers drop out regularly.

The other problem is I'm just not convinced yet about the sound. It's devastatingly loud and clear with the sub and volume up (I only have the smaller SW3) but at normal volumes it sounds a little muffled and confused as to where the sound is placing itself. Some shows where the camera changes quickly and the direction of speech change confuse it, which sounds like speakers dropping out but they're not.

I'm torn as I really don't want a soundbar in front of my TV, but this system is far from perfect and a lack of acknowledgement in reviews for it's downsides is bad, especially at the very high price point.
I can't recommend it to anyone due to that price tag and the issues.
