A word of caution about ground bounce: Ground reflections become an
issue when a speaker is flown and angled down. The proper mic position,
in this case, will also catch the reflection of the signal off the floor.
Reflection arrives ~4ms late...
In this case, you can choose from three options:
• Block the reflection with a baffle that is large enough to
be effective above 100 Hz (so at least 5’ by 5’).
• Do a ground-plane measurement.
