That's what makes C2000B unique. It *looks* like a large diaphragm mic because of the 1" baffle ring. This is from AKG's data sheet:
"This microphone intended for professional and home studio
applications as well as on-stage activities. It consists of a patent
pending one-half inch capsule element which is placed in a
larger baffle ring. This measure gives
the C 2000 B more
forward directionality at high frequencies. The microphone’s
response is tailored to have a broad on-axis rise at high
frequencies, while maintaining a fairly uniform diffuse field over
the entire frequency band. The added presence at very high
frequencies is an asset in many micing situations, especially
home recording studios, while maintaining good feedback
rejection in live sound applications."
It really is a small diaphragm mic, but the way the diaphragm is mounted makes it act like a mid-size diaphragm mic, and in some situations, like a large diaphragm mic. And as Shure says, .75" is really a large diaphragm mic, from a technical point of view, as the relationship between the diaphragm size and the wave length of the highest frequency the mic is meant to reproduce determines the actual definition. Screw all that technical crap. The little bugger is simply useful. Trust me on this- now that you have one, I bet you'll want a pair.-Richie
