Tsk, tsk, Warren -- really:)
I'm surprised the new K's are so much better (rather than brighter). I know that some of the VERY old K-horns used very good drive units but then Alnico prices went sky-hi & they had to revert to more sensible components -- and your '78s are probably in that category. It should be fun refurbishing these!
One of the problems in this complex design comes from the transition from mid to bass; you either achieve seamless mid-bass to mid, or bass to mid (skipping the mid-bass). Klipsch and the K "community" have apparently solved this small issue somehow...
....this is a pair of '78 Klipschorns.....the capacitors are 28 years oldand, so are the drive units, especially the bass units. Not musch tweaking as, maintenance...
