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

I am having a problem with the woofers on my Kappa 9s. The woofers were working but I just wasn't getting any real bass slam. I spoke to Bill at Millersound. Bill said that, and don't quote me here I was up early, that he believed that the inductors were shot. that's the name for the part I think he said, and he suggested that instead of trying to get my crossovers repaired, which would be very difficult and costly, that I purchase an active cross over and Bi amp my Kappa 9. By doing this I would run the active crossover to my adcom 565s connected directly to the woofers and have my Hafler 9505 going to the rest of the speaker.

My question to you folks, do you know where I would set the crossover for the woofer at 100, 80, any thoughts???

Bill also thought that my sound would be cleaner because the woofer portion of the internal crossovers would not be creating any magnetic fields and polluting the other crossovers. So I'm off to the store to get an electronic crossover and see if I can get some bass out of my kappa 9s
