Hi, Thanks for looking. I did a search but came up with little to nothing. We all know have seen/heard or used an 18" reverse folded horn and maybe even a 15" like the old EV (plans are still on their site). Has anyone had experience with a 10" or a 12" in the same style cabinet? Any one have design plans for one? How on earth would a person go about figuring the appropriate dimensions? Why would anyone want one, I do not know for sure.
