It uses a different capsule, kind of an unusual capsule so at first I didn't know what to do with it. It doesn't naturally have much bass response, but it's the quietest 10mm capsule I ever tried, so I wanted to use it. I used narrower venting--this yields the same effect as you'd expect from other mics that people like to mill out to flatten the response, which is it creates a larger and lower frequency peak (and trough) vs. the larger and more numerous holes I drilled in the C (a more normal directional capsule). I then correct that back to reason with EQ. The overall effect is even lower apparent noise as I create an acoustic boost at the frequency where the ear is most sensitive. The tone is enhanced articulation with not as much air as, say, any of the omnis.
So . . . I put it out there to see what people think. It's interesting as a cymbal mic, yields a very dry sound. Ac guitar, nylon string maybe. Or it could be too much for a source, I dunno, I just design the things . . . I would certainly use it close to a source, otherwise it's usually going to be too thin.
I have another capsule design on the drawing board that uses the Q cap plus an S cap in the same case, the omni will have a lowpass around maybe 300Hz which is a different way of attacking the problem and I think that will be very nice as a mid/farfield capsule. Maybe in the summertime.
