No, those high frequency bumps come from the whizzer and are not affected by what's behind the cone. However, they may or may not be highly directional, and hence may or may not be as audible as the on-axis plot shows. Unless there is more complete data available, I'd say you should listen to it for a while first. Initially a 3kHz bump will usually lend greater "presence" and liveliness to the sound. Eventually it will get tiring or annoying if it is too big a bump. At that point, if it happens, you can look into notch filters to remove it.
