I have an old pair of Khorns that were not being used. I was going to sell them, but an associate of mine who's been in the business for about 40yrs said I was nuts. Soooo, I hooked them up to my ATC SCA2 preamp, Arcam Alpha9 amp, and a Naim CD player. They sound pretty good, considering they would likely sound better with another amp. I will putting my old Citation XX amp back on line once I finish restoring it. From what I gather, this may be too powerful for the khorns, I hear they like tube amps.
Back when I first acquired the khorns, I had to replace the diaphram in one of the tweeters. I noticed that its capacitor may have a leak, but its playing fine. The crossovers appear to be original.
I attached some pics of the drivers & xover, I hope they materialize.
