In this vein, here's a double boundary rig that goes lighter on the 
environment than Curt's: http://snipurl.com/1utah   Designed in 1998 
by George W. Swenson, Jr, US Army Corp for capturing 10 to 40 Hz 
from a military artillery training facility.  A single microphone is 
mounted on the ground right in front of the wall to achieve a double 
boundary effect. 4.5 x 9.0 meters. Rob D.
