The last time I measured the upper-bass horn, it started tailing off just below the horn's physical cutoff (115Hz); lets see what the sweeps reveal; I'll do it this weekend (my girlfriend is here now and she goes a bit nuts when I run sweeps).
In the mean time, please define the following:
"Horn default position"; do you mean at a distance of 1 meter from the horn's mouth?
"Perpendicular wall"; please define relative to the firing axis.
Lower-Bass modules are a pair of sealed enclosures, each measuring 16 cubic feet, made from 70mm thick concrete. They are loosely stuffed with fiber insulation; each enclosure houses a single 18" McCauley 6174 driver (paper cones; rubber suspension). They are driven by a pair of Lamm M1.1s.
