I have two AV-15's on order and I'm kind of tired of the sonosub look so I'm thinking of building some tall rectangles 20"x20"x??"(no final design yet). After that I plan to build a GR-Research HT(thinking of 1prAV-3 and 2pr A/V1+). I'm sure I'll get the urge to do other stuff just for fun. You guys have fully infected me with the DIY bug. Well I need some clamps for these projects but I'm wondering what lengths and how many would you recommend I buy for the above projects. Also any links to good deals on clamps would be appreciated, right now I'm looking to ebay.
