ClaudeJ1 Posted September 26, 2015 Author Share Posted September 26, 2015 (edited) Just finished reading all of the posts, I have heard of this upgrade. The question that I have is this: Do the spiders, cones and surrounds on the original Klipsch LaScala 1980s wear out, has their performance degraded over 35 years? Not really, no, unless abused, because they are well protected from the environment. Sealed back, and a buried slot. Besides when a horn gets over 100 db, the cone moves only about 1 MM. Unlike a subwoofer cone, which gets 20X the excursion, this is not a problem for an original woofer.
