Also, just because you get two high quality drivers and throw them onto a crossover doesn't mean that they're going to sound good or work well together.

I know that, thats why I was thinking of going active. BUt if it sounds okay, then I'll stick with it.

Bwcad1: Homage
High Society: Yea it's def worth a shot, but even with active, you have to make sure that you're avoiding all the harmonics and distortion like Jonathan was talking about in his article. That's more what I was referring to then crossover points/slopes. Because if two drivers aren't going to work together, there's no amount of tuning that'll make them sound good. Sorry, I wasn't specific about that.

Crossover 2-way mono
Crossover Slope 2x18dB
Crossover Frequency - 3,000Hz
Tweeter adaptation - -3dB
specs on the x-over,
Now how do I match a tweeter to those specs?

Damn that's funny. I'll be looking for somewhere to use that today while I'm out working with 60 Minutes. Maybe they'll put me in their story. Watch for me on 60 Minutes talking about midgets. LMAO!!!

If that's your crossover, you need to match a mid AND a tweeter to that. You have to get a mid and tweeter that want to crossover around that point and making sure you're avoiding most harmonics and distortion (based on graph measurements I believe).

I'm not totally clear on when to use these, but a notch filter and/or Zobel can be used to help smoth things out depending on whether you're using passive or active crossovers. I think the notch filter is what's used to reduce the harmonic distortions of the tweeter and or mids, and the Zobel is what's used to correct rising impedence by tweeters and/or mids so the passive crossovers will work properly.
