Thank you guys - very much. I'll follow your leads at Klipsch and Bob Crites. This is my first time on this forum - you guys are great.
I've enjoyed reading some of the different opinions on the Speaker forum, for and against horns, etc. Way back when my buddies and I were making money for the first time out of college, we all went out and bought high-end sound systems. My route was Klipsch with Crown 150 amp and pre-amp. Paul Klipsch was my hero back then. Others went the way of Dahlquist, Magnaplaner, JBL. . . . with McIntosh, Phase Linear, and some kits for amps. I've long contended that at low to medium volumes, some of those systems might have had more balanced sound than mine -- seeing how mid rangy the La Scalas are. But dial up a little Rick Wakeman, or a song like School by Supertramp, or Tank by ELP, and crank it up, and nothing could touch my system for kick ass distortion-free rocking.
It's upsetting to hear the recent deterioration in sound but this system is now 40 years old and I suppose it's not surprising that the speakers and/or crossovers may need some parts replaced.
Thanks again guys.
