Ok, so I want to get all the specs and everything ready now so I can start building the box for a future setup. I'm looking at ED's 13Av.2. Just 1. It says to have the box tuned to 30Hz and have the box 2 squared feet. But it also says "DDLoud" setup is 2.2 square feet tuned to 35Hz. I'm assuming it's better, so I'd rather go with that setup. My only issue, is where to start. I tried using SketchUp but that thing is extremely confusing for me. I might just try to whip something up in PS, but I don't understand the tuning aspect. If someone could help me out with the whole tuning idea, that'd be great.

Thanks.
