linkwitz riley

Hey guys, i am a bit new to filter designing stuff. But I have a probleme which matlab doesn't solve that easy (or does it ???)

I wanna implement an linkwitz riley, and now I only found a analog design in the internet and nothing in matlab.

H = s^4/(s^2 + 1,41s + 1)^2

That was the analog design, I don't know how good the phase of this responses, but I hope there is no problem dealing with it.

Basically I need to filter an signal add distortion to the higher part and put them back together.

I would use the binaural transformation for this but, there only came out:

b = [0 0 0 0 ]
a = [1 -2,99994 2,99994 - 0.99994]
(got this coeffs over the octave function bilinear oder so )
and due to the fact that b was zero there is only 0 left.

1. Question, is this the right filterdesign i am dealing with
2. Question, how do I transform it that the coefficients work!!

Maybe some has fun dealing with my stupidity!! hihi

GREEETINGS !!! yip yip!!
