I have a modest sized 2 channel listening room and have done a fair amount of room treatment using Acoustimac products. I find them to be top quallity in fit and finish. There are quite a few options to choose from and they look great. With the right amount of panels, they can help transform your room into a really good listening space. They help minimize reverb and side reflections. I have ordered the DIY panels as well and they are the same quality. I was very satisfied with the ordering process and customer service. Eric really helped me out and was even able to give me local shipping options/prices. Very good people to deal with.
