where did you get the idea that the K52 series of drivers is only good to 800 Hz.? You were misinformed. Best regards Moray James.

I am just pointing out that Klipsch documents an 800hz crossover on the Cornwall III. Klipsch's crossovers don't typically push the lower registers as hard where the horn crosses (and shouldn't because that is where the distortion is).
My assumption and I maybe wrong is that the reason the 800hz crossover and horn combo with the Ti driver didn't get moved back down to the 600hz - 700hz (as in older speaker lines) is that it does not perform as well down there. Now hit the driver with high power and what will you have, probably not good sound?
Similar to reasons the pro horns typically bumped up in frequency range, they play better louder and are less likely to self destruct.
I could be totally wrong and for the investment, I hope so and there is an easy fix. I just don't think I would push this driver that low very loud plus being on then edge of the horn Fc doesn't help.
Easiest way to see if it is the horn ringing is to pack it in rope caulk. Removable and a good test. If the problem is not solved, a larger horn and possibly driver will be in order.

The same size driver is used in a CW2 and in Chorus 2 crosses at 600Hz I believe. The story was that Klipsch lost the mould for the K600 I suppose they also lost the mould for the K601 as well ad they had to use the K701 in the H3 as a result. The K700/701 is the device with the problem playing low because it is too small. Klipsch would get a big yellow BS button from me if I had one to send to them. Those who have switched out to the ti diaphragm in the CW2 and Chorus ll with its larger horn are as far as I know very pleased with the results. The K55 for those with a taste for phenolic diaphragms can play very low indeed very low. Best regards Moray James.

The K-55 will work down to 100 Hz. (although not very loud) it's the horn that's the limit.
