Ok, to Harvey and the King, I will run it by again. Traditionally, 6 micron Mylar takes more inertia to make it move than a 3 micron, so it takes more pressure to move the center point of the Mylar. Now there are many factors that are involved. Distance of the gap for one, tension is the other, and the back plate has factors as well. There is also the air pocket behind the diaphragm that contributes to this. Its stiffness affects the ability of the film to excurse.
Ok, thinner Mylar could and can handle the same SPL based on all of the above factors, but in my experience, and I would think yours, but only you can answer that one, most 3 micron products don’t. Again, this is “my” experience. I checked AT’s site today, but could not get the rated thickness of the Mylar, but I am pretty sure it is 3um..If I am wrong Harvey, then my fault. Its SPL rating is high, but all ratings are limited by the amplifier load factor, and at 100 ohms, the AT takes less loading than the 200 ohm C1, so amplifier factor is a big difference here. Since there is no Ad Hoc committee on the regulation of specs, many specs made claim to at a specific testing point are not the same under conditions and are done so to make them look good. To be clear on this, I am not saying AT does this, but others do.
I have used the 4033 in real world applications. I have publicly stated on this thread that it is a well built mic, and I am not AT bashing. All I am saying is the C1 has handled more SPL for me in “my” application experience. Nothing against AT here, I am only offering my opinion on my findings.
Like I said, you’re findings may be different. In addition, most mass manufactured capsules have more variation in tension, back plate and air pockets. It is hard to keep quality control over this variable, so you have to be on top of it all the time to ensure consistency.
Hell, Stephen Paul can do it on a sub Micron capsule, but all of his variables are accounted for. Agree, or don't agree, this is my position. I am not always correct on everything, and I am not a designer by trade. Like Stephen Paul, I am self taught by experience, but am not near a Stephen Paul.
My guess is he forgot more about this shit then I ever knew.
