I would definitely have them neutral for audition purposes. Pick the one that sounds best with them all neutral. It is the best way to compare. Also as you (if you) upgrade to better electronics in the future you may find they do not have tone controls. Then you're out of luck.
TESTING SPEAKERS
when you are testing speakers to hear if you like them should you always keep the BASS & TREBLE controls to there 12/O'Clock settings which would also be called NEUTRAL is that the right way? or should you adjust the BASS & TREBLE controls to your personal taste.
