I'm putting together a new system and the stock front speaker locations in my CRV have the tweeters all the way up at the front of the windshield, and the mids are right about in the middle of the door panels. This is a pretty significant distance, and to be honest I am not exactly sure what that might do to the front image. This system will have time alignment, and I am planning on running an active setup for the front stage (I will not be running rear speakers).
My question is, is there a general rule of thumb in terms of trying to keep tweeters and mids within a certain distance in order to preserve an element of sound quality? I am curious what others thoughts are, and if there might be a good recommendation for an alternative tweeter location.
