Beam speaker technology, redefind
Over twenty years ago, Yamaha re-invented home theater with the YSP-1 soundbar, and have been refining beam technology ever since. In this latest model, Yamaha's original YDA-141 high-performance amplifier with twelve ultra-precise DSP-controlled beam speakers mounted on the top (six on each side) create unique height channels with ceiling reflections. With realistic Dolby Atmos® playback, it delivers an amazing sound field that surpasses conventional soundbars.
The foundation of Yamaha's original Beam Speaker Technology consists of two key elements: a side-by-side array of multiple small-diameter speakers, and the use of advanced digital signal processing to precisely control the timing of the sound emitted from the array. When each of these speakers simultaneously emit the same sound, the multiple sound waves overlap, creating a sound "beam" of strong directional waves. By slightly shifting the timing of the sound from each speaker with the ultra-accurate digital signal processing the directivity of the beams can be precisely controlled and focused to reflect from ceiling surfaces to create a remarkably realistic sonic field where the sound seems to come from above. Moreover, the technology has been by customized exclusively for various three-dimensional sound field formats, such as Dolby Atmos®, DTS:X™, and AURO-3D®, enabling extraordinary real-height reproduction that fully takes advantage of the sonic brilliance of these sound field formats.
True X Surround 90A is a system that brings new innovations to home cinema. With a slim-bodied soundbar just 71 mm tall, it features multiple, meticulously selected speaker units, encased in a sturdy, highly rigid cabinet supported by large resin legs with a substantial contact area exceptionally solid build quality for an audio device. In addition, combining a subwoofer boasting new Symmetrical Flare Port® technology with two fully wireless rear speakers featuring built-in battery power provides unprecedented flexibility and a profoundly authentic cinematic experience.

True X Surround
The True X Series brings together the cinematic immersion of Dolby Atmos for your TV with the freedom of portable speakers you can take anywhere. Enabled witha touch of a button, the True X speakers connect with the True X Soundbar to create True X Surround, producing exhilarating realism and clarity for your movies. The True X speakers are surround speakers which can be put anywhere in your room, for flexibility as well as optimum sound. These speakers also double as portable Bluetooth® speakers. Just press the Solo button and you've got music wherever you want it.
Elegantly shaped, Perfectly tuned
The custom eye-shaped oval speakers are key to creating a slim soundbar with distortion-free, immersive surround sound. These speakers deliver rich midrange tones and powerful volume with fewer units, ensuring a clear, natural sound field without acoustic interference. By optimizing the speaker's structure and magnetic circuitry, we overcame challenges like cone strength and high-frequency clarity, resulting in distortion-free, immersive sound. The outcome is a soundbar that offers a sleek design and powerful, balanced sound for an exceptional listening experience.

Premium components,Ultimate performance
SURROUND:AI™ technology employs cutting-edge audio processing performance. Thanks to Qualcomm® QCS407 64-bit SoC (System-on-a chip), also used in our flagship model of the AVENTAGE Series AV receivers, Yamaha's unique surround sound feature automatically generates ideal sound field effect depending on the movie scene. Enjoy your favorite contents with sound as if a team of Yamaha professional sound engineers were fine-tuning audio for each scene.
The term “Soundstage” refers to how sound naturally resonates and reverberates in a particular space, and it varies greatly among homes and movie theaters. Even with the same audio source, the listening experience differs dramatically, making it difficult to recreate the impact of a theater at home. To overcome this, Yamaha pioneered the concept of creating soundstages by reproducing concert hall acoustics in home audio, releasing the world’s first Digital Soundfield Processor, the DSP-1, in 1986. Developed after more than 30 years of DSP research, Surround:AI™ revolutionizes the home theater experience by analyzing and optimizing DSP parameters five times per second. It dynamically scans each scene in real time, identifying key sound elements dialogue, background music, ambient sounds, and effects and instantly fine-tunes the surround sound for breathtaking immersion, seemingly increasing the number of channels.

Feel the Depth, Hear the power
The subwoofer of this system employs Symmetrical Flare Port® technology, newly developed through meticulous Particle Image Velocimetry (PIV) measurements delivering powerful, deeply resonant bass. The symmetrical horizontal/vertical port structure ensures extremely smooth release of the strong air flow generated during bass reproduction. As a result, port noise has been reduced by 20 dB compared to conventional models, enabling pure bass reproduction that is both powerful and deep.
Where True sound comes to Life
With a history spanning over 130 years and being one of the world's largest manufacturers of musical instruments, Yamaha fully understands the very moment of sound creation, and continues to be relied upon by world-famous artists for its audio expertise and live mixing consoles. In addition, we maintain first-class research and development capabilities in all fields related to sound and music, and we have brought our long experience and extensive knowledge to sound creation in the True X Surround 90A.
