Aside from the fact that it's not audible, what's wrong with having a lower than needed response frequency just the risk of feedback?

You don't want a low power amplifier almost clipping when there are inaudible infrasonic rumbling "sounds" from traffic and aircraft.

A speaker will not produce the very low frequency sounds. The feedback will be at the most sensitive frequency which is about 4kHz for a cheap little speaker.
 
I doubt the tiny microphone can detect infra-sound.

Even if it were a huge woofer you don't want infra-sound because it wastes power producing sound you can't hear.
 
You can't close mic brass or reed instruments with electret mics because of overload problems. You really have to be careful how high a sound level they will receive.
 
An electret mic inside a drum is overloaded. use a dynamic mic (coil and magnet) that is designed for high sound levels.
 
Hi, Audioguru,
It was a tongue in cheek reply to the posts further back between Mikebits and Colin55.
One, an American and one Australian both having a spat over the mic answers. :)
 
Isn't Colin an American who now lives in Australia?
He wrote articles for Poptronixs magazine in America?
