Im looking to setup a warehouse building with sonos. The warehouse measures approx. 110ftx65ft. It is 2 stories. So approx. 7000 square feet for each up and downstairs. Im thinking about using play 3's. My question is in that setting, how many play 3s would be ideal for that situation. Its going to be a boutique type building so don't need to be rocking out however would like to be able to produce sound throughout each floor. Whats the best suggestion to how many speakers to put on each side of the 110ft wall. Im assuming that will be the best situation. Thanks in advance.
