Klipsch horns put out an incredibly large sound even at moderate volume. The drivers and crossovers are the same in the kHorn and LaScala. There is an enthusiast community for these speakers and you can get upgraded parts as well as plans to build your own.

My understanding is that the drivers are fairly mediocre, even for their time, but in combination sound quite pleasing. They are a big favorite of mine, but I don't have a proper room for them. I do have a set of Heresys.
