[Elecraft] more Bass in K3 with PR-40

[Rich]

I'm not disagreeing with the recommendations at all, but it seems that 
the rationale may be a bit off for some?  I believe the vocal range for 
standard bass voices starts at about 87 Hz, "super" basses might get as 
low as 65 Hz (C2).  Perhaps the key point is that intelligibility is 
concentrated around 1-2K Hz.  Yes?

Interesting to listen to recordings of low bass notes with "standard" 
microphones and then with mics that are sensitive to 50 Hz, and then 
listen to background noise and A/C noise.
