Thanks for that, interesting. However:
Every room I've ever set up subwoofers in is different, considerably so in
some cases, so generalisations about 'room placement' are simply that,
generalisations. 2 wall midpoints huh? Opposite or adjacent walls? What if
some walls have large window area? How does door-placement figure? It's all
conjecture until you have the available subs in the particular room.
Knowing the theory is great and all but knowing how to adapt it is better -
and a good ear (or laptop / software / microphone) should always take
precedence - even when it goes against the theory.
In the end it's all subjective anyway as different people hear bass
differently - different frequencies louder for some, quiter for others...
When all's said and done some time in the room with a variety of source
material is the only way to set up subwoofer/s. Also taking into account
whether it's for you, or for someone else. If the latter then they need to
be part of the set-up process too.
