Low pass crossover setting & slope for Kappa 9?

I have a pair of Infinity Kappa9 speakers and need to buy a preset module for my AR EC22 crossover. I do know, that the Kappa9 spec sheet shows 80hz but that seems low for an external crossover and the specs do not show the slope speed, 12, 18 etc. I can obtain a 90hz with slope of 12 but not sure if this would be ok? I would like to know the exact setting and slope if possible. Thanks

Call Infinity and ask them if you want the correct answer to your question.

Don't bother with Infinity. Asked the same question 10 years ago for the kappa8's and they had no idea. I don't think Infinity ever published exact specs. Bill at MillerSound might know.

Ask him if the 9's hi-pass/low-pass on the PCB can be bypassed.

Yes, I did call Infinity but they did not return my call. I will give it another try next week. I was just hoping that there were some Infinity fans out there that have used the Kappa 9 in a Biamp application and/or is currently using a external crossover on the Kappa9.
Thanks....Denniscleo

Here is a link to an excellent Infinity site (in German) and the specific page for the Kappa 9, listing crossover points.
