JohnK. I want to first say that Khorns are EXCELLENT, but very limited because of the corner placement necessary, for me anyway. The build and makeup of the walls(home construction) can make or break some of their magic, keeping in mind that I listen a 100 db, and have said so many times. I have heard Khorns sound good, to fabulous, depending on room, acoustics, etc. One of the best Khorn set ups I heard was in a large basement in which "corners" were built using concrete blocks/wood panels. The corners of the basement were too far apart. So that's the story with the Khorn, ime. Lascalas are easy to work with, and I have found a pair of subs to mach them perfectly and coherently(was not easy). As far as the upgrades. Most products are designed with a price point in mind. The weakest part of the Lascala, imo, are the cabinets, specifically the dog houses(Klipsch lingo for the woofer portion of the box, in case you did not know). They are not well damped from vibration, and as you turn up the sound, it just gets worse. I learned this from Jim Thiel(may he rest in peace)before he was well known. I did not know him that well, but met him, and he shared ideas with some of us. Other companies spent time with box coloration(B&W comes to mind), but, I believe he nailed it. Since then, there is much info about the damping of the Lascala boxes and, other mods for them. Again, the basic design is great, but with available learning, parts, etc, this all leads to upgrades. Every hi end company I am familiar with, has had upgrades available, with a basic start out "chassis". Audio Research comes to mind. Look at every race car. What is being done to them to get this greater level of performance. All I can say, over and over, is that they allow me to listen and "get into" the recording that is playing. They are very "coherent", to my ears, because all three drivers within the cabinet work so well together. Sorry, but you asked.....later....
