True X Surround 90A

Overview

The True X Surround 90A is Yamaha's flagship sound bar system from 2025. Yamaha announced it in August 2025 for sale from September 2025. One package holds the sound bar (SR-X90A), a wireless subwoofer and two True X Speaker 3A wireless surround speakers with charging cradles and wall-mount brackets. The bar is 1180 mm wide, 85 mm high and 143 mm deep on its feet; Yamaha says it is 2.8 inches tall when wall-mounted with the included metal brackets.

Yamaha lists new eye-shaped front left, center and right drivers with dome tweeters, twelve 1-1/8-inch beam drivers for the height channels and a 6-3/4-inch driver in the subwoofer. The two surround speakers run on power or their built-in batteries, and in Solo mode each works as a Bluetooth speaker.

The TV connects over HDMI eARC or optical, and an HDMI input takes a console or streaming box. Wi-Fi, Ethernet and Bluetooth bring music through Yamaha's MusicCast platform, with Spotify Connect, AirPlay 2 and TIDAL Connect, and services such as Amazon Music, Pandora, SiriusXM, Deezer and Internet Radio. There is no built-in voice assistant. Yamaha lists Clear Voice, Bass Extension, Adaptive Volume for low-volume listening, Surround:AI and the sound modes 3D Music, Stereo, Straight and All.

You control the bar with its buttons, the included remote, the TV remote over HDMI-CEC, or the MusicCast Controller app. The box contains the bar, subwoofer, two surround speakers, the remote with batteries, power cords, mounting brackets and the guides.

What the specs mean

• Speaker setup not stated: Yamaha does not give a channel count for the 90A, so the table lists it as not stated. The user guide's display shows front, center, surround, height and subwoofer channels.
• Dolby Atmos, DTS:X and AURO-3D: Dolby describes Atmos as sound that can be placed around and above you. Yamaha calls the 90A the first sound bar with AURO-3D, and the user guide also lists DTS-HD Master Audio, DTS-HD High Resolution, DTS-ES and DTS 96/24.
• Beam height channels: the bar aims sound beams from twelve small drivers at the ceiling, so the table counts it as up-firing. The user guide has a ceiling-height setting for this.
• HDMI passthrough: the HDMI input passes 4K video at up to 60 Hz with HDR10, HDR10+, HLG and Dolby Vision, plus ALLM, and the user guide lists HDCP 2.3.
• HDMI eARC: HDMI.org describes eARC as the newer Audio Return Channel that carries high-bitrate formats from the TV to the bar.
• Full setup included: the wireless subwoofer and both surround speakers are in the box.
