From what I've read since starting my research 6 months ago, MB Quart's would be the way to go for SQ. A seperate tweeter is always the best - so they say, and it makes sense. Are those a/d/s's on the dash good for imaging? I've been advised to keep the tweeters as near as possible to the mids to level out the path length between left and right. You can raise the soundstage without literally putting the speakers higher up. Apparently! : p
