Hello! I'm seeking some help with Acoustic Panel placements, and where a good place to purchase acoustic panels are. I was looking on realtraps.com and saw they were priced right around $150-$200. I'm trying to get by with finishing off the room the cheapest way possible. So any estimations for how many panels, where to purchase, and where to place would be very helpful! Below is a picture of the room. Basically, there are two speakers and the room is rectangle!
