True, but I think you should just try it out and see if it is an improvement or not and not get caught up in thought experiments that scare you into inaction.

Afterall, I can change the treble of the sound just by leaning a bit forward or back in my sitting position or repositioning the speakers - the room has more effect I would think than the tweeter per se.
