I purchased 80's era Khorns some years ago with intentions of flipping them, what with my ill informed opinion horns only for PA systems. Boy was I wrong, I could instantly hear much potential, and this with 80's era Khorns, perhaps the worst of the lot, K401 metal exponential horn, this thing rings like a bell, and probably the worst crossover ever in any Khorn, this with the add on crossover in bass bin. So I tore out the crossover, replaced with Crites type AA, Crites cast frame woofer, now we're getting somewhere. Next mods were John Allen A55G mid driver, B&C DE120 tweeters, this along with Volti tractrix mid horn and tweeter mounted on custom baffle, now we're really talking! Next mods were a reworking of the Crites crossovers, this took place over a period of a year, incremental mods, this meant modifying the AA crossover to Type A, replacing all caps with combo of Jupiter, Audyn True Copper Max, Duelund Silver Bypass, Duelund tin plated copper, point to point wiring, Jantzen solid core copper and litz copper wax impregnated inductors, Voodoo binding posts. Result is Khorns that sound stage, image, much better tonal balance, natural timbre, even more resolution/transparency than stock Khorns which are nice in this respect, and then we have the inherently wonderful macro and micro dynamics, sense of live performers in room that Khorns deliver. From here we play with a variety of amps, class A SS, push pull EL34, 845 SET, two different variety of 300B SET amps, and just about to receive Bendix 6094 (unique variety of EL84) push pull monoblocks.
I couldn't have pulled this off without both Crites, Volti in the positive direction and the many criticisms of Khorns in the negative direction, much to learn from both parties.
