If you’re using tone controls there’s something much more seriously wrong with your system or room that should be addressed before resorting to tone controls. Just my $0.02 FWIW.
I tend to see only the positive of having tone controls. I have a Schiit Lokius connected to my tape loop. I can turn on and off the tape loop and hear exactly how the Lokius is impacting the sound versus not having it in the signal path. I think it is a worthwhile and fun piece of equipment.
With it I can add a bit of sparkle to the highs or a touch more bass should I choose which I sometimes do.
I tend to think of a speaker's voicing, as with any other piece of audio equipment, as that as interpreted by the designer. So why not alter (slightly) this presentation if not 100% my preference in general or for a particular song?
Also just my $0.02 FWIW.
