No one has mentioned line array (open baffle or not) speakers. I have only read about them, but I wonder if they might address the OP's call for "clarity" or "accuracy" or whatever magic word equates to what he wants.
Do larger planar speakers produce more accurate sound?
Planar speakers generate sound pressure via vibrating membrane panels. The excursion of the membrane x radiating area= sound pressure. This would mean that for a given sound level, membranes have smaller excursion in larger planar speakers than in smaller ones. Does this mean that larger speakers will produce more accurate sound?
I am not talking about the obvious benefits of the larger speakers in terms of low frequency production, so let's not get into that.
