Klipsch La Scala diagnostics/repairs

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.

Many thanks Mickey.  How much did you pay for them?

Got with Bob Crites and he's been very helpful.  Ready to buy a pair of crossovers from him, seeing how mine are 40 years old.  Question for the board:

Bob gave me the resistance that each of the speakers is supposed to have -- I checked mine and they're all consistently 1 or 2 Ohms lower than the spec, but both sides match.  When speakers go bad, do they tend to go up or down in resistance?

Also, if I pull the bottom panels to visually inspect the woofers, am I able to see anything without physically removing the big 15" speakers?

Thanks for the advice.

Gaskets - that's what Bob suggested as well.  For the midrange horns.  What do they do, just deteriorate over time?
