I am excited as well. Many times I have simulated with various long excursion drivers, only to find that some don't do xmax in band until 2x thermal power in the desirable boxes. I was beginning to wonder about the designers intensions. Now you're talking about getting all the travel these drivers promise, and not replacing them all the time. I know all too well about frozen, open and detached VC's. The shop I used to work at sold competition car audio as well as hi-fi. I have seen VC's deform into the gap, but I never saw a "backplated" coil or ripped suspension in a good box.I really want to build a pair of these horns your working on. I have done enough simulation and real world stuff in the last few years to already see the potential. I want subs that can modulate my voice.(so please test that capacity while you are torturing the prototype)
