Hi efficiency forward sounding drivers or horns do this well.
Agreed. That's why I've been pushing the high end JBLs...you have the best of both worlds; power *and* finesse, imo. They rock hard, but can be delicate if need be.
Klipsch is ok too, but they're not in the same league as the high end JBLs, imo. However, Klipsch are more reasonably priced. As it should be. I wouldn't pay $10K for a Cornwall III.
At the low end, I guess Cerwin-Vegas, but those have clear colorations, perhaps ones that enhance the sound when playing rock and metal recordings, but in the long run one would get bored with them and sell them.
