This keeps popping up -- cut the lows.   There may be plenty of reasons to cut the lower frequency ranges at times, but "no contribution to intelligibility" is not one of them.

There is plenty of research around that demonstrates that infrasonic content between 20-80Hz contributes to a less tiring listening environment, adds to presence and realism (the sense you're not listening or talking to the world through a 1940's telephone set) and contributes to improved intelligibility in certain consonants, especially among male speakers.

If I wanted to sound like a cockatoo I'd just use the <brand deleted for fear of reprisals> radio with a 2.1 Khz mechanical filter crystaled so that the low end cutoff was 300Hz :-)
