ok, the mic is here and my measures (with rmaa) didnt point out so much difference.. i hope your test files will be more helpful
(oh, just to mention, i think the mic doesnt sound bad at all, i think ill use it on a-guitars perhaps )
the first graph are some very old bose speakers ("302", 2-way with some 8" woofers).
the second one are my samson resolv 65a.
