John--
Played over my speakers I _am_ hearing lower mid-range spatial
imagery in the center. Not a hole at all.
Of course, there's lots of overlap with a 100 degree angle. Looking
at the NT1-A's polar pattern, <1K Hz sounds are unaffected up to 70
degrees left and right of center axis. Sound reflections from
distant surfaces like the lake are likely in this bandwidth. Any way,
nice results and possibly an example of how one can aim these wide
cardioid mics at key HF sources angled up to 140 degrees and not lose
the <1K Hz sounds in the center. HF sound sources will probably be
less present in the center compared to a 60 degree angle. Rob D.
