I wasn't joking Devill, I didn't know what you wanted.
With tweeters, you could send them a full range 20hz-20khz signal.... but to reproduce a 20hz signal, a 1" tweeter would need like 10" of xmax //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
So you need the mid to do that work and hand off to the tweeter through the xover. Dre has some upper bass drivers in his door that don't like to play the midrange in the audio spectrum.... say 800hz-6khz. They so play well up to 1.7khz he says.
A good rule of thumb with tweeter x-over points would be to double the Free air resonance (fs) value.... I like to double it and add a few hundred hz myself. So for Dre, you need a tweeter with an fs value of like 800-950 at the most. Lower would be preferable though.
