A 32 foot pipe, putting out c1 (16 Hz), is about as low as pipe
organs go unless you're taking into account the interference signals
created when different ranks are combined. So the MKH20 should work
since the specs show a 15 Hz low end. What's your interest in
recording lower than pipe organs typically put out? Just curious.
