I Suggest you post your question at the www.madisound.com
discussion board. There are many fine people there to offer assistance.

Madisound will LEAP you a crossover.
They can also supply you a completed crossover, you just plug in (solder) and play.

Since you cannot measure, and have only a slight clue about what your doing, in my less than humble opinion this would be the best route.

However, once an X/O is LEAP'd you still need to fine tune by ear. i.e., you need a mess of caps, coils and resister to really optimize the unit.

I have LEAP and LAud, so I know of what I speak, but NO I do not have time to do yours.

Another suggestion is Bodozio (sp) Sound Easy, about $200 last I checked. It strikes me that you seem to have an interest in this. Would make a nice investment in your speaker building future. Also LMS/LEAP packages can be had used on the net from time to time, they are not all over the place, for about 1000-1800.

Another option would be the Vidsonics box. You hook up the amp and it has outputs for 2/3 ways, and you just dial in the X/O you want. It's a lot of fun to play with. Has settings for 2-12 pole X/O's. Play with topology until your hearts content. My daughter (15) just optimized speakers I built for her, to HER ears liking. Daddy LEAP'd first and gave her a start point, and then allowed her to adjust topology to what she like. Daddy dis-agrees on choice, but only a little, she came up with a completely different X/O topology all by experimentation.

So those are all idea's for you. And like I said, if you simply want to be done with it. Have Madisound LEAP you and X/O and just build it or have them build it.

Good luck,

Good luck.
