Do you think that EVERY AKG mic rated at 145dB will actually hold up at 145dB SPL? Inquiring minds want to know!!! And will it sound GOOD micing something at 145dB SPL?
Rose says... "what's an AKG and why do I care why SPL is sleeping with it???"
..and personally, I think AKG may very well have stress-tested their capsules for 145 - I seriously doubt it could take it for very long - and hell, the ears would give out long before the mic does at that level!!!! For a brief second before the ears go, you wouldn't be able to tell if it's the capsule distorting, or simply your ears!
