How big is the room (floor area and volume) and how far away from the tv is the microphone during your measurements? I’m trying to figure out if, for a short while (6 months), I can use the onboard Audio+ system until I move into the new place. The watching room now is 14’x22’x8.5’ and I usually watch movies/shows at 72-75 dB at seating area (12 feet away).
