Things to know about the LaScala? in Technical/Restorations Posted September 3, 2001 I have 2 pair of La Scalas. but unfortunately, have never seen RF-3s. Soundog has described the La Scalas very well. I think they have a few flaws and only one cannot be removed easily. The worst flaw is a ringing in the squawker horn. That is fixed by wrapping the squawker horn in rope caulk or other clay that will not harden or a product called Dynamat. The bass horn also suffers from some resonance affecting male voices, but it is subtle and not usually offensive. A horizontal brace across the bass horn would probably solve that problem. The tweeter is mounted the the rear of the baffle and "looks" through a 19mm deep "tunnel". This causes some harshness in the highs and is fixed by front mounting the tweeter. Klipsch makes "Z" brackets to do just that (the tweeter opening must be enlarged). Some of the 80s models had a really poor sounding crossover network (Type AL) and it has to be replaced. The newest, Type AL-3 or Al Klappenberger's crossovers are good replacements. Finally, the La Scala's bass horn begins to roll off at 60 Hz and little bass is present below 45 to 50 Hz. Nothing can be done for this, but buying subwoofers. The bass output is in proportion to the rest of the music and the result is very natural sounding, but they will not shake a room. That said, I will probably never be without a pair of La Scalas; I like them that well. Most of the flaws could be solved by Klipsch and I doubt if I surprised them with my assessment. However, the cost of my modifications on an assembly line would probably not be worth it.
