Band hall is 45' x 40' box with a 15' tall drop ceiling. Incredibly loud and just clapping in the middle you can hear your sound bounce all over the place.
I tried to get a quote from a local company and it came out to 20 grand for treatment. Completely unacceptable by my admin. What can I get done myself for 2k that will be effective?
Wall panels? Baffles of some sort? Not sure how much weight the drop ceiling could hold - would need to be anchored above the drop ceiling more than likely.
