for a PZM you need a hard surface.
well, yes and no. any practical pzm has rubber pads to protect them from
floor vibration. the mousepad i used had a rather hard surface, and soft
rubber underneath. actually just used the pad so that i could move the
microphone around and protect it from scratches and other damage. i'd
expect the lf absorption of that pad to be pretty minimal, particularly
since its area is so small compared to the relevant wavelengths. so the
relevant boundary here is the floor, not the pad.
of course, high frequencies are messy, but as i said, with a bit of eq,
for this particular application it worked.
I'm pretty sure it worked, and it's quite a creative way
to solve a practical problem. I did the same on one occasion
where the organiser of a theatre production didn't want to
have any mics on stage or close to it - just gaffa-taped four
KM84's to the walls. It worked well (but not in mono :-).
