room responses etc.

Yesterday I saw a high voltage 220kV transmission line mast, one "arm" was
still unused. Sould give 30m elevation. But that would be to dangerous.
And I'll always run into noise problems: wind!



:::WHAT!??!? You have been arrested? And for doing measurements? Hmmm... you

Just a joke!


:::Well, this sounds all very nice... but putting the speaker on an infinit 
baffle
:::or something is not going to help you, you want to know how your speaker
:::behaves in a free-space environment. Mounting the speaker in a large baffle
:::will alter the speakers natural zero's and thus will give a diffrent 
responce.

I didn't make my point very clear. The idea is: if I  can't measure
the free field response, I'll change completely to half space response,
ie. speaker build into infinite wall.  This means baffle when measuring
(flat on the ground, speakers point to heaven).  And baffle when
using. The remaining error would be different "baffle" size.  Maybe it
is not desireable to have a half space response anyway.

Now, this all is not such a big problem.
If I keep the original recordings, I can always apply an inverse
transfer function on it, if I finally get it.
And may be I'll apply filters to the impulse responses for
"better" sound anyway.
