We needed some sound absorbtion acoustic panels for a game room that was turned into a conference room at work. With industrial open ceiling and two of the walls glass, the echo and sound quality was horrible. I ordered custom size panels and hired someone to install them. Installation was labor intensive with a lot of measuring and drilling into drywall. The panels are up and look fantastic and do help with our issue! The representatives were responisve to answering all of my questions. I would definately recommend Acousticmac for anyone looking for solutions.
