Wayne, Thanks for your timely reply to my post! I am wondering if I might substitute Baltic Birch Plywood for the MDF in your kits? Or is this a bad idea? What do you think about using AcoustaStuf or Deflex pads in place of fiberglass stuffing? How much stuffing do you use and where is it placed? What would it cost to ship a pair of completed Two Pi's to Dubuque, Iowa 52003? Last question: what is the "connector panel" you referred to above? Blessings, BobCat
