Hi, I have a retail store with two rooms- one is 2600 sq ft, the other is 1100 sq ft. I want to stream music from a desktop computer, mostly from internet radio, pandora, spotify, youtube. I want the volume and sound to fill the room nicely, but not be too loud for conducting business and having conversations. Occasionally we will have a party and want to crank the sound. I'm thinking of 2 Play 5's for the larger room, and 2 Play 1's for the smaller room. Does that sound about right? Thanks!
