Thanks for the comments. My speakers will be used in a home enviroment and will rarely be pushed(comparitively speaking anyway). The 2226J loaded in the conical horn should get close to the efficiency of the 2123J mid. The 2426J will of course need some padding. So, I'm certain the individual drivers will match well in terms of efficiency. The bigger obstacle, of course, is the crossover network. I'll need to do some more research on it, and see what looks like the best/least compromise and then see what I can come up with in Spice. I'll keep the group posted. Thanks! Jerrod
