A Total Racket
Ahhh, acoustic treatment: the "magic beans" of of the recording world. Their pitch: "want world class recordings? Invest in our special foam! Not only does it have no appreciable effect on the sound quality of your recordings or mixes, but it looks dumb and disfigures your walls when you take it down! On a tight budget? Don't worry, it's only $8,500 a square foot!
Having used this stuff, I can say with all honesty that it is MUCH more of a pain than it is worth; especially considering the ABSURD prices these companies charge. How much is a box of foam really worth anyway? What does it cost to manufacture? 12 cents for a thousand boxes? What's the markup on this stuff, ten million percent? After several years of carting this junk around and trying to find a way to effectively mount it, I have decided that I just can't imagine bothering with it ever again. Not worth it at half the price.
