Wayne let me ask this so I am completely clear on the best way, what type of back do you use on the 7 Pi professional (7PI corner horn, mid horn, high freq horn,) or is it run open backed? I would like to Replicate it as closely as possible! Your Comments on that combination with the stoekit ( spelling) impressed me. Is it still possible to review that thing, or is that over with? What a great idea! Thanks Again for your time & patience,
