In Reply to: What to do with a pair of KLH Model 5s? posted by texanater on December 8, 2014 at 08:38:03:
texanater, You have a fine set of loudspeakers in those KLH Model Fives.
I concur with the need to replace the electrolytic caps, specially those in series with the tweeter. Chances are they have dried out and are way below spec value by now, resulting in low tweeter output. Dayton Audio metalized polypropylenes caps from Parts Express are inexpensive and work well. I just did this in a pair of KLH Sixes and they now have plenty of high-end sparkle.
Your crossover coils will be fine, as likely are the resistors. Maybe squirt a touch of contact cleaner in the two switches. No need to replace the terminals.
In addition to the woofer surrounds and dust caps, did you reseal the midrange surrounds too? (The woofers in my Sixes need resealing but that entails cutting out the grill cloth and its black backing cloth. I'm reluctant to do this since the grills are in pristine condition.)
Incidentally, I suspect that Henry Kloss voiced his designs with the grills in place. Certainly so with the Sixes since the grill cloth is not removable: It's epoxyed in, as are the drivers.
You're probably aware of the Classic Speaker Pages info. (See link.)
