So I listened yesterday to RF-63s with a Marantz receiver. It seemed pretty lacking in the bass department. I tried other speakers too, and other floorstanders did better with bass (especially low end bass) than the klipsch. That has mostly to do with the crossover, right? I was pretty disappointed. I wonder how the RF-35s would compare to the RF-63s I heard.
