Having wondered around and pointed the SASS/MKH-110 at things, often
also the SASS/MKH-20 at the same things my take is the big problem with
this idea is that what's down in that low bass in the way of natural
sound is not at all the same everywhere. So we are going to have to
continue to try and work around the man made noise if we are trying to
reproduce a close resemblance of the original site.
Note switching back and forth between MKH-110's and MKH-20's will make
the MKH-20's sound like they are giving weak bass.
This low frequency end supplies more than just spaciousness, it's also a
lot of the emotional content of a place. Even the infrasound enters in,
we feel it at frequencies well below what our ears can handle.
I'll point to the magnaplans I have for speakers for this sort of thing.
They can give the low sound you feel without making it too loud.
Probably because of their very large flat surface area compared to a
focused cone on a regular subwoofer. They still do not reproduce the
sound as it was out there, but a lot closer. They won't give that
focused thump of a subwoofer cone, but natural infrasound is not focused
like that. The funny thing is folks tend to think that they give poor
bass as they are so trained to the incorrect bass of cone speakers.
