IIRC, Alpine had a passive delay circuit on the F#1 crossovers to compensate for tweeter placement. Obviously this would be extremely limited, probably only A, B, or C placements, but how do you accomplish this? Would there be a way to do a custom passive delay with various ms steps?

Upon further research, the F#1 crossover has different positions, but they only affect rolloff and attenuation to compensate for positioning, not time delay.

I don't think there is any way to do analog time delay, at least not accurately. :(

crossover filter architecture only affects phase in the passband, and too much phase shift causes its own problems.

Jim Fosgate's Gavotte processor did a lot of surround-ish processing in the late 80's, and I think it was all analog... might be worth searching, think there are some posts about it.
