"I think what I was running into was that I tend to listen at lower volumes and unlike the Klipsches we have, these really don't perform well at those volumes."
I suspect those are two very different sounding speakers.
My experience with B&Ws in general is that they are not great low volume speakers. Klipschs I have heard in general are better, probably due largely to their high efficiency.
Your ears may still be used to the Klipsch sound resulting in disappointment with the B&Ws
If you think that is not the case, then you have two choices
1) try to tweak the system to the speaks and speaks to the room better to suit your tastes. Go back and listen to the same speaks again in the dealers setup if that is where you heard and liked them. if you still like what you hear there, then figure out where the differences may be between that system including listening room and yours and tweak yours accordingly.
2) If you no longer like the B&Ws as much as originally, punt on the B&Ws and try something else, perhaps more Klipsch like in overall efficiency and sound, maybe even another pair of Klipschs as an upgrade.
By the way I've owned B&W floorstanders and also heard and liked very much the RB 25s. They sound very different. YOu have to determine what kind of sound it is exactly you are going after. Chances are one will fit the bill much better than the other.
