Thought I would share my experience using a 5.1 system with a 32” tv.
Living in a smaller home, I’ve learned to use visual cues to help the space feel generous, but I really wanted to have an immersive experience. Limited to a 32” tv because of all the art & stuff on the walls, I bought a 4k Samsung tv (not a lot of choices), then added a beam/2. Then added 2 one st’s for surround and a sub mini.
The result is remarkable. Adding sound adds so much space with a small tv! With dwellings becoming smaller for many good reasons, sound really does help the space feel fuller.
A yet relatively unexplored benefit for Sonos.
