Ihcho,
The xover on the LaScala as well as the other xover upgrades with show themselves mainly in the highs and mids. The lows are improved but it's not as much as the highs and mids.
As far as the KLF-20's go, I can tell you from personal experience, having owned mine in stock form for 4+ years and now with upgraded xovers for 2 years, the KLF-20's are a much, much better speaker. Again, you notice it in the highs and mids. The highs will not be as harsh but rather smoother while still maintaining great extension. You will hear more clarity in the mids and they will be smoother and warmer.
You haven't heard Klipsch until you've upgraded the xovers.
