How to Set Speaker Volumes for a Home Theater System

The Sonos system allows you to set different speaker volumes as they're acting as a group. You can individually adjust all of these separate speakers. And then when you raise and lower the overall volume, it uses it in proportion. They also make speakers that fit into your wall. So if you have like, if you don't have a place to put rear surround speakers, you can actually have a large flat speaker that sinks into the wall.
