Most conductors are ignorant about loudness, acoustics, & bow speed, but most of the audience, board members, and administrators are probably just as bad or worse. They all hear with their eyes. The conductor is just giving the audience, board members, and administrators a way to hear with their eyes, because they can't really evaluate music with their ears. That's why we still hear the same old tired "use more bow" comment. (Oh, and also because the same dumb idea is taught in education schools, to k-12 string teachers.) And, that's why I'll move around too much, when conductors ask for "louder." Conductors don't want to be taught by bass players, about bow speed on the bass. So, just give the conductor the visuals that they want to make them think you're playing louder by moving the rest of your body in a more energetic way, pick up your paycheck, go home, and cash your check the next morning before it bounces. It's why some bass players play standing up, in orchestra. There are still enough dumb conductors around who think that the better bassists playing standing. And, of course, the C-extension . . . even if you don't use it on the rep on a gig, if the conductor sees the C extension, they think the bassist is a serious player. Most conductors are dumb, but bassists like Karr shouldn't try to "educate" them. They are too arrogant to be educated (partly why many of them are dumb--arrogance hinders the ability to learn). Just give them the visuals.
I got the above idea from a jazz electric bassist, actually. An idiot jazz band director wanted more bass, so the bassist turned around to the amplifier, pretended to turn up the volume knob, then moved around energetically. bobbing his head, etc. It worked. The director thought the bass was louder and the balance was fine.
