I found a local insulation supplier in my home town that had the OC703 for about $9 sheet, pretty cheap compared to the online sellers and that there is no shipping charges. I purchased enough to start with 2 8ft SuperChunk Bass Traps for my front wall. Royce, thanks for the Bryan's referrel at SensibleSound. Him and I talked for about an hour today and he was very helpful and knowledgable on this subject. If only I could have the knowledge that Bryan or Ethan Winer have in this area, it would be scarry.
