Klipsch La Scala diagnostics/repairs

I bought a pair of Klipsch La Scala speakers brand new back in 1978 (yeah I'm an old guy now).  They've been wonderful, but in recent years they don't sound like their old selves.  It could be a factor that several years ago, during a corporate relocation, they spent a long hot summer in a non air conditioned storage down south.  Whether it's the crossovers or the speakers themselves, something ain't right.  Do any of you folks have recommendations for how I might go about getting these old friends checked out and brought back up to standard?  I now live in Wilmington, NC, and am expecting that I'll likely have to take them out of town to get them in the right hands.

Thanks for your help

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.

Talk to al klappenberger as well. Alk engineering is his company and I bought some new crossovers for my lascalas and they sounded great. You can also adjust the mid and high with his crossover.

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

you should be OK with lower resistance, open or very high is bad, IF you are not hearing a physical rub you should be good.
when you are in there do those gaskets !

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