Klipsch LaScallas vs Klipsch Cornwalls?

I'd heartily second Elevick's recommendation for Coincident as a good alternative. They have been of very few speakers I've heard that offer the speed and sparkle that satisfied the expectations I had from coming off of LaScalas for so many years. Disclaimer: I am selling a pair, which would not likely apply to you as they are larger and being sold locally. Other conventional dynamic driver speakers I might check out are Silverline and Merlin if you require high-sensitivity options. I've owned two pairs of vintage Heresy's, one of which I tweaked out practically as far as I could, to make it sound fuller and reinforce the bass. Ultimately I couldn't get the satisfaction from them, but they are certainly fun speakers and offer big bang for the buck if purchased locally (they are pretty bulky and heavy to ship otherwise). In the Klipsch line, if you were sticking with them, I'd point instead to Forte II's I think someone's already mentioned...although for your particular tastes in music the Scalas or Cornwalls would be better if you had the space. The only reason I think the LaScalas MAY work in your room is that you said you did not listen at loud volumes. I did find they throw a better stage though in a larger space.

If he does not play them loud, which was what he said in his first post, room size becomes a much smaller issue. Possibly a non-issue.
I have KHorns in a 12' x 13' room. When I play at moderate volume the room is not a problem at all. When I play loud, the room quickly takes over and ruins a good thing. That's why I have a lot of room treatments and bass traps.
btw: The way KHorns push into the corner, they may make more sense for Recordho's room, I don't know. But they are the biggest speakers I've had in that room and I now feel like I have more room than ever. He definately won't have bass issues with KHorns either (until he plays loud).

I would go for the LaScala and tweek them with the help of the Klipsch chat group people....I used to run these with the Trend little wonder and the sound was perfect and very affordable....BUT after I moved to Altecs and now JBL.

the cornwalls or heresys in a small to medium room...but all the spica models still sound incredible.

I find it hard to imagine that someone who really likes the Spicas will find happiness with any of the Klipsch models. None of the Klipsch will image or soundstage like the Spicas.
