Honey, I shrunk the TV

This is a first-person account of pairing a Samsung Q990D soundbar with two Music Studio 7 speakers using Samsung's Q-Symphony orchestration. The author wanted wider, less "crowded" front staging and tested reassigning the bar's satellite speakers as fronts, then bought Music Studio 7s to add true rears/fronts. Setup revealed quirks: the Studio 7s refuse to join if the router uses DFS channels (forcing a specific 5 GHz channel), and Q-Symphony only works when all devices are on Wi‑Fi - mixing a wired eARC soundbar with wireless speakers for simultaneous output didn’t work despite past claims. That opacity raises doubts about whether Q-Symphony sends true channel-separated surround signals or just applies a common virtualization/mix.

After some listening the author noticed audible echo whenever sounds moved between front and surround; testing showed the TV’s built-in speakers were playing slightly before the Wi‑Fi speakers. Disabling TV speakers via Q‑Symphony proved impossible on pre‑2026 hardware, so the author entered the TV service menu and set Max Volume to 0 to effectively mute the panel while leaving Q‑Symphony and external speakers functional. That solved the echo, but the writeup calls out poor documentation and a perceived feature lock on newer TVs.
