Even if you can't hear the 17Hz fundamental of a low C# you can hear it's harmonics, some of which are unique to that specific C#, and all the C#'s below it. One of these is the second harmonic (34Hz) which just a plain old B string C#, but the third harmonic (51Hz) is unique to C#'s equal to or below 17Hz (8.5hz, 4.25, 2.125, etc.). All of these extra harmonics allow the brain to kind of fill-in-the-blanks making you hear the 17Hz note even though you can't hear the fundamental.


Edit: Here's a link to a better explaintion and a sound clip demonstrating the theory

I'm not following your math. Isn't the first harmonic supposed to the first octave? That would be around 34 Hz. And the open B string is about 31 Hz. Maybe I am confused, but not following you.

Sorry, that's a typo it is supposed to say 34hz and not 24hz, I'll fix it.
And I'm pretty sure the first harmonic is the fundamental and the second is the octave.

Regarding the low C# string debate:

1) It doesn't matter whether or not the low C# fundamental is audible. Heck, a lot of bass cabinets can't reproduce the fundamentals of the lowest notes on a four string, but because of the harmonics, those low notes can still be heard.

2) You can use the low C# string to play notes other than low C#!

Fundamental = full wavelength = fundamental frequency = 1st harmonic

octave above fundamental = 1/2x fundamental wavelength = 2x fundamental frequency = 2nd harmonic = 1st overtone

fifth above octave above fundamental = 1/3x fundamental wavelength = 3x fundamental frequency = 3rd harmonic = 2nd overtone

etc.

I seriously dig that bass! I wouldn't care If i could hear the fundamental note but when stuff starts falling off the walls from the vibrations it causes that's when I'm down with it !

I do not think I can wrap my brain around an 11(the lurning curve gets pretty steep when your my age)

but i'm building a 7 that i'm looking forward to !
