Default Crossover?

So I am attempting to build the m&k s-150thx speaker. I heard from Nrik that the tweeters have a crossover point on the 2 outer ones that cover more midrange than the middle one. If I wanted to go with an active crossover would I just put some sort of filter on the 2 outer ones to keep them from going high and a filter on the middle to cut the low? Also, do I leave the woofers bare and just run them straight to the terminal for hook up from the crossed amp? I am new to crossover designing and have no clue what I'm doing. I don't want to blow up anything!!

I have been looking at the behringer ultra curve pro. Any thoughts on this one? Also, do they make a rca to xlr cable? I'm using the preamp outs on my Yamaha v-1400 for the front mains.

You can get XLR to RCA converters cheap from many places. Any music supply or even Parts Express. I usually make my own cables anyway.

On the DCX: I have one. Very handy for design and setup. I find it has a slight edge or digititus some would say. Others think it is just fine. Anyway, it stays on my bench as a piece of development equipment. Many like the mini-dsp boards.

I suspect that speakers of this type would be difficult for even an experienced designer to copy
Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency

Pete I think you are correct after much research and talking with a builder friend. I think we might go for the bose L1 pro system. I've heard it and love the sound it puts out.
