Hi.
I'm new here - please be gentle.
Being somewhat familiar with both consumer and pro audio, I had the opportunity on 7-1-1999 to purchase a used (abused) pair of Klipsch La Scala industrial series speakers for $250 / pair (along with a bunch of other damaged equipment as a lot). Theseare the La Scala separates featuring the road case construction.
One of the La Scalas was perfect, the other one was missing the access panel and it's K-43 woofer was blown. I replaced the woofer with a new unit (9-30-1999, cost $82.50) and fabricated a replacement wood panel with multi-ply plywood of the same thickness and used foam weatherstripping for a panel gasket ($22.11)
Great results.
I have used these in pro-sound applications ever since.
Way back when, I used to sell the Klipsch line when these were new at Tech Hifi in the early 1980's, I learned then that these had piezo tweeters - as mine do - tweeter model K-77.
I never liked piezo tweeters - they seem to only make sound at one frequency (about 4KHz) and lack clarity.
After a night of hard commercial use, the high-end will get very sloppy and ear fatigue is an issue.
I would like to replace the piezo tweeters with dynamic or compression tweeters (which I believe would sound great). I know that they would not be as indestructible as piezos but I am a careful operator of equipment with many years experience and understand the design limits.
Does anyone have technical details on how to modify / update the crossovers and an idea for a suitable replacement dynamic or compression tweeter?
not many small horn tweeters being made nowadays... but I have not done my research lately.
Did Klipsch once upon a time use dynamic or compression tweeters in their product line? if they did, a bolt-in replacement would be a very nice solution if I can get my hands on a pair.
Neither vintage parts nor Klipsch name brand parts are necessary for me.
I just want to bring this design to it's maximum potential.
As you can see by how I buy things, I am thrifty. I require a solution that is not pricey. (Even though I worked for a very high end audio manufacturer in CT from 1988-1994, I never subscribed to the idea of spending big bucks to get awesome sound.)
your help and insight is greatly appreciated.
thank you kindly.
TCB.
