Sony continues to bring forward its novelties for this fall and the HT-A7000 soundbar presented previously is now joined by the HT-A9, a wireless home theater sound system that will feature 360 ​​Spatial Sound Mapping technology from the manufacturer whose objective is to diffuse sound. speakers in the room creating a more immersive soundstage.

For this, the equipment has the sound field optimization system which measures the relative height and position of each speaker to recreate the effect of having up to twelve virtual speakers installed in the room from of its four physical speakers, emulating a larger home theater set. and offering out-of-the-box support for Dolby Atmos and DTS: X.

With an elongated cylindrical appearance reminiscent of other smart speakers or WiFi Mesh network adapters, the HT-A9 set uses two microphones on each speaker to measure their relative height and position, allowing us to do these measurements whenever we make a change of decoration in the room, when adding a curtain, rug, furniture, etc.

The four speakers included in the kit connect directly wirelessly to the main control unit so there are no cables to run around the room (except for powering each speaker) and feature X-Balanced type drivers with a rectangular shape that maximizes the diaphragm area to, according to the brand, “achieve richer bass while maintaining sound pressure and dialogue clarity.”

With HDMI eARC, 8K and possibility of adding an external subwoofer

The speakers also feature Wide Directivity Woofer technology with reduced cavity effect by minimizing the depth of their concave shape. It works in conjunction with a 19mm diameter Soft Dome type tweeter to improve high frequency response.

In addition, as is already common in this type of surround sound equipment, upward-facing speakers have been integrated to reflect sound signals from the ceiling and achieve theoretically more convincing surround sound that reaches above. the head.

The set can work right out of the box, but we also have the option of adding an additional subwoofer with which to improve the low-frequency response, something that we have to purchase separately. It will be possible to choose the SA-SW5 model with 180 mm woofer and passive radiator offering 300 watts or the SA-SW3 with 200 watts of power, 160 mm woofer and bass-reflex output.

As for the musical possibilities of the set, it is compatible with Hi-Res Audio definition and with the 360 ​​Reality Audio system available on Amazon Music HD, Deezer, nugs.net and TIDAL. We also have DSEE Extreme technology which can scale all compressed digital music files in real time and replace the high frequencies lost during said compression.

Another novelty this season is that the audio system will be compatible with 8K HDR at 60 Hz and 4K HDR at 120 Hz video signals, with Dolby Vision and with Acoustic Center Sync so that, in the case of a BRAVIA TV, we can achieve greater integration with the TV speakers.

Finally, it should be noted that the set will offer compatibility with Spotify, Chromecast, AirPlay 2, Google Assistant, Amazon Alexa, it will have WiFi, HDMI eARC and Bluetooth connectivity.
