Those Klipsch's aren't the most placement sensitive, as long as they're 2 or so feet away from the back wall. They can sound pretty dynamic and good - but only if you're driving them with WARM tube electronics. SE tube amps, and some PP tubes need only apply. SS on these speakers are ear killers! I had the KLF 20s for a while - similar sound, but more bass and coherency. If you grow to love the Klipsch's realistic dynamics, but grow to loathe the un-fixable horn colorations (shouty), seek out Dynaudio.
