I'm sorry but I don't think we received your order. Please resubmit it. As for plans, you don't have to buy a kit to get them. Check your mail, I've sent the plans. There is also a printed copy included in the kits.Use R13 insulation, and line the bottom, back and one side. Install a 1 x 2 every 18" as a brace, and tie opposing panels together. Make them fit snugly so there is a little bit of tension. I like to make the speakers mirror images, every π Speaker pair I've made has been that way.
