Sony HT-A9 360 Spatial Sound Mapping Home Theater System + Subwoofer

In a world filled with an overabundance of similar-looking, sound-alike soundbar systems, it appears that Sony is attempting to shake up the “sleepy” home theater in a box category with some new technology, albeit with an “incomplete” 4.0.4 speaker surround sound package that lacks a dedicated center channel speaker and is missing a subwoofer. Don’t worry, they do offer two “optional” matching powered subs.

As far as I know, the new for 2021 Sony HT-A9 home theater system [manufacturer’s website link] [video] pictured above is the world’s first wireless surround sound system to feature integrated upward-firing Dolby Atmos / DTS:X effects speakers mounted on top of each of the satellite speakers.

It’s also the first system I am aware of in which each of the speakers features built-in microphones for simplicity of system setup (and voice control). Sony’s cutting edge “360 Spatial Sound Mapping” technology [video] allows extreme flexibility in placement of the four speakers within your room [video] while creating the most immersive home theater experience ever offered by an all-in-one HTIB package.

The four light pearl grey cylindrical shape speakers each feature a 0.75″ soft dome tweeter, a wide directivity rectangular shaped X Balanced woofer, front bass port, an up-firing X Balanced Dolby Atmos / DTS:X effects speaker, and dual microphones.

The control box features LAN connectivity, as well as an HDMI input and HDMI output with eARC and support for 8K/60Hz and 4K/120Hz passthrough, and an S-Center output jack for setting up Acoustic Center Sync with one of the following 2021 series of TVs — X95J, A80J, A90J, and Z9J, although the TV’s built-in speakers are not timbre-matched with the HT-A9 speakers.

You save yourself some money when you buy the Sony HT-A9 system together with a wireless subwoofer versus purchasing them separately. The larger 300-watt SA-SW5 [link] is the better of the two compatible subs with a front-firing 7″ woofer plus a bottom mounted passive radiator. You can purchase the Sony HT-A9 + SA-SW5 bundle at Amazon.com.

The smaller 200-watt SA-SW3 wireless subwoofer [link] features a 6.3″ driver and is front-ported. You can buy the Sony HT-A9 + SA-SW3 bundle at Amazon.com.

6 total AC power outlets are required — one to plug in the wireless transmitter control box, four for the speakers, and one for the subwoofer.
