u know -I can't help but notice all of this talk about 'in an ideal situation' blah blah blah
we all know a car is far from the ideal situation, so why all the concern about it?
I understand knowing what would be idea, because that will help to guide you as to how to place speakers, but to talk about it like it's been talked about recently is pointless IMO.
Sure, time delays shouldn't need to be used, sure tuning shouldn't need to happen...all in an ideal set-up....but there really isn't an idea set-up...so how is it a relevant point?
just an observation
as for tweeter positions - there are a few different schools of thought - back when, I know that mounting everything in the kick was idea, now it's different though, pillars seem to be getting the best results according to what's winning comps...
but I'm sure in the next few years, it will all change yet again...lol
