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.

I've had this sony system for about a month and it replaces a Samsung system.the difference is very noticeable, the Sony is a great improvement over the Samsung.

Excellent but with a proviso
An excellent set of speakers, i was worried at first by the lack of a centre speaker, but the sound mapping is so good that you do not notice that it is not there.
The proviso - you really do need to add the optional bass speaker to get the best out of this set up.

SONY HT-A9 Home Theatre Sound System
I recently purchased a SONY HT-A9 Home Theatre Sound System & it's amazing there are 2 issues that I was quite concerned about, the S Centre Speaker & the Pass Through which they recently did an update to rectify that Pass Through issue. The S Centre Speaker is a different issue altogether when connected to my Tv there was a loud continuous hissing sound & SONY had to arrange for an engineer to come out & change the TV's Motherboard which rectified that hissing issue. You then had to redo the whole setting up of the TV again which I suppose was a minor in the whole scheme of things. My annoyance also comes from the cost of this premium product, I was lucky the price had been reduced but it still cost a considerable amount of money !. SONY need to do better, but the sound from that system is amazing & sublime it does what it says on the tin, & that's why SONY are the very best at what they do.

Easy set up, excellent quality
Very happy with the HT-A9. Took minutes to connect up to my PlayStation and projector, with a nice in built self-calibration system to optimise the sound.
Great to remove the bulky speakers, amp and wiring from my old 4.1 set up.
Audio is excellent, very immersive - although now planning to add a wireless WA5 subwoofer to complete the experience !

Great sound
I've had other surround sound devices in the past, all connected by cables, not all have been great. The HT-A9 is great, I am so impressed by the quality of the sound and the immersive feel that it bring to films and gaming, just brilliant

Great sound
Bought in early Jul 2023. All's well except that the volume of the rear speaker is very low. Technician who attended to the issue on-site could not do anything to resolve it.

Excellent Home Theatre
These speakers look great and sound great. I had the Sonos Home Theatre and these are so much smoother. Excellent highs and lows. These work so much better with my Sony Bravia TV.

Sounds fantastic (with SW5 subwoofer)
These sound amazing but you do need the subwoofer to get good bass. I'm very pleased with these speakers.
