This is a response curve from a ribbon tweeter. To understand the difficulties faced by speaker designers, just look at the solid green line for starters. This represents what's known as the "on-axis" response. The measurement microphone points directly at the tweeter. Yikes!
Even straight on this thing's all over the map. It's about as far away from "flat" as a roller coaster.
But, now look at the other lines. They are what we hear off-axis, meaning the microphone (like the listener) sits to the side of the tweeter. These aren't different by a small amount. Each response differs by many dB.
And as Audiophiles we worry about tenths of dBs?
Voicing
