most difficult speaker to please


Which speakers have you found MOST difficult to drive, place etc??

Along with the two above, mbl 101s, notoriously power hungry. As far as placement goes, I've been lucky, the speakers I've owned have been pretty easy to place, which is the reason I picked them, not having a dedicated listening room.
I literally saw an small Adcom 60W/Ch amp go up in smoke trying to drive a pair of the orig. M-L CLS speakers... Luckily it was the dealers misfortune and not anyone who owned it! ;-)
I saw some Infinity IRS Betas make an ARC D250 "weep and moan" (clipped like a barber)...
Im definitely gonna second Dave's Apogee Scintilla. Loved the sound..but that 1 ohm load was a killer on all but a select handful of amps that could drive them back then..
