Why Multiple Subs?
I want to start my posts with a lengthy discussion on the use of multiple subs, first why they should be
used, and then how they are setup.
First I think it a good idea to go over some history behind the concepts. I will start by going all the way
back to my PhD thesis (30 years ago), which was on this precise topic. At that time I was studying the LF
(low frequency) sampling statistics in small rooms and how these were affected by the rooms shape.
This is important question in sound measurement because it tells us how many points (samples) we
need in a reverberant room to find the true source sound power given that each point has variations of
the desired quantity due to the non‐diffuse nature of the sound field at LFs in small rooms.
