Performance Breakdown
Mixed Usage (8.1/10)
This setup excels across media—TV, music, and movies—thanks to its seamless Sonos ecosystem integration, broad format support (Dolby Atmos, Dolby Digital), and low audio latency.
Dialogue & TV Shows (8.3/10)
The dedicated center channel and speech-enhancement tools deliver crystal-clear dialogue, while low-latency performance ensures syncing with video content remains tight.
Music Performance (8.4/10)
With the Sub 4 on board, bass reaches rich sub-bass territory, while mids and highs retain clarity. Ideal for genres from hip-hop to orchestral, though the absence of a graphic EQ limits fine-tuning
Movie Experience (7.8/10)
The surround sound is robust, with palpable rumble and vivid detail—even if vertical height channels rely on up-firing drivers (“phantom height”). Night mode helps keep late-night sessions neighbor-friendly.
