A-Pillar Speaker Placement for Sound Quality?

[Wicks]

Ohh yeah, BTW.

I believe it was Robola46 who fabricated an actuated metal plate to cover a set of components in his doors or kicks.

That would probably solve the unused driver, passive radiator situation....

But a ways out from my fabrication ability at the moment......

There is going to be no way to tell if on axis vs off axis or a pillar will sound good. Some speakers do much better on axis and some other do fine off axis. You need to get in your car and listen to all the spots before doing the install. I thought about doing a A pillar and talked to a few guys that did it and they all said you will more than like need some type of time alignment. The path lengths with a pillar can get really out of whack compared to door or kick panel mounted. Sit in your car and play with the spots and find the one you like best.

I don't know the full context of the explanation you got about time alignment, but with small tweeters crossed above 2 kHz there is very little benefit to time alignment on those channels. Our hearing is more sensitive to level differences above 2 kHz rather than timing. This means your nearby tweeter needs to be turned down to sound roughly the same level as the far tweeter. That will help center and tighten the vocal imaging.
