I tried to calculate Ve = Vad/Qd with Qd = 1/Qts, and get 1.1 cft for the Delta 12LF (Theater 3), shouldn't it be around 3-4 cft? PiAlign.exe gave me the same results. I used the T/S from the Eminence website.Also, what is the difference in sound for a PI alignment vs the traditional QB3 or C4/SC4 alignments?
thx, Tom
