Bell termination of musical horns being truncated at 90* is a convenience thing since it is close enough to being complete for the expanding waveform. But there is still some sharp reflection at the edge of the termination which forms standing wave distortion back into the throat.

A LeCleach horn profile is more complete, efficient, and lower in distortion. But is obviously much larger in diameter.
