I traveled from Rome to Milan last Saturday to see the Top Audio, the largest Hi - Fi and HT Show in Italy: there among other events I attended a high efficiency demo held in the memory of The Colonel by an Italian loudspeakers & tube amps maker, Kiom.
The demo was focussed on the low wattage low distortion concepts, and the loudspeakers used were a set of 77 Klipschorns without the upper wood structure. I enclose a couple of pictures.
The mid horn and the tweeter were simply sitting on some carbon blocks, the crossovers were still completely factory original and only a complete rewiring had been carried out (excluding crossovers).
A small piece of wood was set into the mid horn to damp ringing: I tapped the mid horn and it was well dumb by the way, a configuration like that allows the tiniest phase and angle adjustment for each squawker / tweeter set.
I managed to have a seat in the sweet spot, so listened intently and can say the sound was really delicious, though in my opinion the credit can be given to the naked configuration only in part in fact, the amps sounded really good.
Conclusions: naked Klipschorns exist and sound good. How better (maybe just different?) than normal models I cant say unless I test it with my own equipment, but I am tempted to reach for my tool set and spend next weekend unscrewing wood panels

P.S. I wish to thank Klipsch Audio Technologies Technical Support: I asked for a copy of my speakers manuals, and these guys sent me all the stuff in days in *.pdf format very kind of them.
