Each satellite speaker houses a 100mm woofer, a 20mm high-resolution tweeter, and an 80mm up-firing driver for height effects. The center unit features a 25mm tweeter flanked by two 45x108mm woofers. Sony developed new aluminum diaphragm drivers specifically for this system to improve clarity and high-frequency performance .
The core of the Trio's immersive sound is 360 Spatial Sound Mapping (360SSM), developed in collaboration with Sony Pictures Entertainment. This technology generates up to 24 virtual speakers, creating a wide and tall soundstage that extends far beyond the physical units .
The system supports the leading immersive audio formats: Dolby Atmos, DTS:X, and IMAX Enhanced. The only cable connecting the three speakers is for power; all audio is transmitted wirelessly . A new Direct Connect feature allows the rear speakers and subwoofer to connect wirelessly to a compatible Bravia TV without needing the soundbar as an intermediary hub
.
The Trio is a foundation for a much larger system. It can be expanded with optional Bravia Theater Rear 9 or Rear 8 wireless speakers. More critically, it supports adding up to two wireless subwoofers (Bravia Theater Sub 7, 8, or 9 models), making it possible to build a fully wireless 5.2.4-channel or even 7.2.4-channel setup .
Calibration is handled by Sony's Sound Field Optimization technology, which now uses a USB-C microphone plugged into a smartphone to analyze and correct the room's acoustics .
Unveiled alongside the Trio were Sony's first televisions featuring its long-awaited True RGB Mini LED backlight technology, which uses independently driven red, green, and blue LEDs for "purer" color, reduced blooming, and greater brightness . These models represent Sony's premium TV offering for 2026, with no new OLED models in the lineup
.
The Bravia 9 II (XR90M2) is the flagship model, equipped with Sony's best RGB backlight drive technology. It is available in 65, 75, and 85-inch sizes, with a super-sized 115-inch model also offered (the 115-inch version lacks the new anti-glare, low-reflection screen found on the smaller sizes) .
The Bravia 7 II (XR70M2) is the more versatile, slightly more affordable entry into True RGB technology. It features Sony's "RGB Backlight Master Drive Pro" and is available in a wide range of sizes: 50, 55, 65, 75, 85, and 98 inches . Both the 9 II and 7 II support Dolby Vision and Dolby Atmos
