Sony introduces HT-A9, a wireless home theater system with 360-degree sound, Dolby Atmos and DTS: X

Sony continues to advance its novelties for this fall already the one previously presented sound bar HT-A7000 now the HT-A9, a sound system for wireless home theater what will come with the technology 360 Spatial Sound Mapping from the manufacturer whose goal is to spread the sound of the speakers throughout the room creating a more immersive soundstage.

For this, the team has the sistema Sound Field Optimization which measures the relative height and position of each speaker to recreate the effect of having them installed in the room up to twelve virtual speakers from their four physical speakersthus emulating a wider home theater suite and offering out-of-the-box compatibility with Dolby Atmos y DTS:X.

With an elongated cylindrical appearance reminiscent of other smart speakers or to WiFi Mesh network adapters, set HT-A9 uses dual microphones in each speaker to measure its relative height and position, allowing us to make these measurements every time we make a decoration change in the room, when we add a curtain, carpet, furniture, etc.

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

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

The speakers also feature the tecnología Wide Directivity Woofer with a reduced cavity effect by minimizing the depth of its concave shape. Works in conjunction with a tweeter tipo Soft Dome de 19 mm in diameter to reinforce the response in high frequencies.

In addition, as is already common in this type of surround sound equipment, they have been integrated upward facing drivers to reflect sound signals off the ceiling for a theoretically more convincing surround sound that reaches overhead.

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

As for the musical possibilities of the ensemble, it is compatible with the definition High-Resolution Audio and with him sistema 360 Reality Audio available on Amazon Music HD, Deezer,, and TIDAL. We also have the DSEE Extreme technology that allows all compressed digital music files to be scaled in real time and to replace the high frequencies that are lost in said compression.

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