Overview
Sony built the BRAVIA Theater Trio as a three unit system whose wireless front speakers stretch the soundstage past the edges of very large screens. A plug in microphone and phone app calibrate the sound to the room.
A wide, cinema style soundstage with automatic room tuning suits big living rooms and large TVs.
Who it's for
Movie fans with large screens and room for separate front speakers get studio tuned surround. Those who want a complete package with bass and rears in one box should budget for add ons or look elsewhere.
Pros and cons
- Soundstage wider than the screen
- Automatic room calibration
- Dolby Atmos and DTS:X
- Expandable with rears and dual subwoofers
- Subwoofers and rears sold separately
- Inputs and wattage not listed
- Heavy, large system to place
Performance notes
Separate front speakers spread sound sources apart, and spatial mapping adds virtual speakers so effects seem to come from beyond the cabinets. Calibration measures room reflections with the microphone and adjusts output to suit them.
