I am using Wright sound Mono 10s on my "77 Khorns with ALK X-overs and no matter how "complicated" the music there is none of the harshness of SS left. Even with the Moody Blues "A Question Of Balance" at 100 Db.
If your Lascalas are made with K400 horns, have you damped them? If you have type AA networks a nice easy mod is to put a 1mF capacitor across the two 2mF caps. This takes a lot of the energy off the tweeter at Fs (3500Hz)
Go to http://www.alkeng.com/ and take a look at Al K's work with Klipsch X-overs. Go to http://www.klipsch.com and click forum. There is a lot of good information there and many knpledgable posters to help you.
