Most of us have seen frequency response charts before – maybe when looking to purchase a new microphone or a new set of speakers. […]
SBIR (Speaker Boundary Interference Response) – This is a term to describe how the proximity of a speaker to a hard boundary (wall/ceiling/floor) will change the response, especially in the low end.
