Sony HT-A9 Wireless 4.0.4 System + Subwoofer Bundle
6 total AC power outlets are required — one to plug in the wireless transmitter control box, four for the wireless speakers, and one for the “optional” wireless 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 black powered subs with bundled pricing that saves you some money.
When it was released to consumers in 2021, the $1999.99 Sony HT-A9 home theater system [manufacturer’s link] [available at Amazon] became 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. (The new for 2022 Platin Monaco 5.1.2 WiSA wireless home theater system has upward-firing drivers on just the front left and right speakers.)
It’s also the first system in which each of the wireless speakers features built-in microphones for simplicity of system setup (and voice control). Sony’s cutting edge “360 Spatial Sound Mapping” technology allows extreme flexibility in placement of the four speakers within your room while creating the most immersive home theater experience ever offered by an all-in-one HTIB package.
Each of the four compact wall-mountable light pearl grey cylindrical-ish shaped wireless speakers are 12.3″ high, 6.3″ wide, 5.8″ deep, and weigh 6 pounds, and feature a 0.75″ soft dome tweeter, a 2.8″ x 3.2″ rectangular-shaped wide directivity X Balanced woofer, front bass port, an up-firing 1.8″ x 2.1″ oval-ish 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 compatible higher-end Sony television models from 2021 or 2022, although the TV’s built-in speakers are not perfectly timbre-matched with the HT-A9 speakers.
The larger and better-sounding of the “optional” Sony wireless powered subwoofers is their 16.1″ high, 10.9″ wide, 16.6″ deep, 28.7 pound, 300-watt SA-SW5 [manufacturer’s link] [available at Amazon] which features a front-firing 7″ woofer plus a bottom-mounted passive radiator. The smaller, less powerful model is the 15.1″ high, 7.9″ wide, 15.8″ deep, 23.1 pound, 200-watt SA-SW3 [manufacturer’s link] [available at Amazon] which features a 6.3″ driver and is front-ported.
How to Buy this Entire System You actually save yourself a bit of money by buying a bundle. You can purchase the Sony HT-A9 wireless surround sound system together with the larger 300-watt SA-SW5 or smaller 200-watt SA-SW3 wireless powered subwoofer at Amazon.com. System should be delivered in TWO BOXES, perhaps not both on the same day.
