Hey guys

How do I design a cross over with limited available specs for the drivers? I have acquired drivers that came off the mission m6ci center and plan on building 2 little
 2way bookshelf's

I am not sure what you are going to do as far as box design is concerned without the speaker parameters.
This site is quite helpful for XO design. https://www.diyaudioandvideo.com/Tutorial/DesignBuildCrossover/

I see the frequency response is 65 - 20,000Hz, but that will include the tweeter.

Hey curlycat thanks, yep that's about what I found as well, very new to diy, so trying to figure what I can do with this information.

Also not exactly sure what to do with the box :-\

http://techtalk.parts-express.com/forum/tech-talk-forum/38661-the-speaker-building-bible       be patient a lot of info here

the easier  but correct way out would be to find a forum member that can measure and design a proper X-over and box for those drivers, and where you will be using them,  and then you build it out   :)
