Hi Guys,
since a lot of you understand the acoustic physics of these animals much better than I, I have a question related to the op. has anyone ever done an accurate measurement of how much you would have to close down the opening around a 511 thats mounted in the port of an inverted A7? It seems like there is agreement on 75 sq inches, but how does that relate when the filler boards are removed and the horn is inside? I have both utility and magnificents and wonder if they could be made to sound even better than they do?
thanks to all,
scott in nc
