A new video from GIK.
I found the extent by which a large null was reduced with room treatment to be both interesting and perhaps a little surprising. That said, they have added a LOT of room treatment for this demonstration, far more that most would do for a domestic room. (Presumably).
The "before and after" recordings are also interesting. Is it me, or does the "after" recording sound perhaps a little dead? Maybe you can go too far with these things?
This is a short video, and well worth the time to watch I think.
