where did you get this idea?

Good question. It turns out that one of the mics with most exceptional bass
extension is a 1/2" DPA mic. Their 1/4" ain't bad for bass, either.

AFAIK, bass roll-off is usually set by an intential leak between the
diaphragm and the atmosphere. If the leak is really tiny, the bass is more
extended. However the mic may then become susceptible to having the leak
unintentionally blocked, making it susceptible performance changes or damage
due to air pressure variations related to changes in elevation or weather.
