Those EV's are great speakers. I'm a big fan of JBL Pro and the new Eminence Magnums, but there are plenty of other good drivers I like a lot too. Your EV's, TAD's and Altecs are good examples.How about using a PC emulator on your MAC? PiAlign.exe is an "old school" DOS program that doesn't take much to run. So you'll be able to use it just fine with an emulator.
