If you take those very same 6" drivers and horn load them, the modulation distortion sideband levels will drop 15-25 dB...depending on the exact design of the driver...thus rendering the modulation distortion inaudible.

This is not a new phenomenon:

Well, I'm glad I'm on the right track on getting information. Thank you for the links!

If you want a kind of objective example that mimics what the guitar frequencies will do (ie sound like), make a sound like "woooooo" of a single tone and then let the back of your throat vibrate that tone so the tone sounds "rumble-ly". It is almost like when you try to create two different frequencies at the same time (which I think is impossible or at least very hard to do). The vocal cords are creating one frequency (voluntarily) but then you can make your throat create a quite ugly sound which is also of a frequency but much lower. Then apply that phenomenon/sound to the much higher pitch of the guitars of the song's introduction.

If you do that technique and say the word "honk", it does sound like a duck's honk...to me anyway, heh. It also kind of sounds like when a person's voice goes through that teenage change too.

Does that explain it better? I hope so.

I'm going to get this home studio done ASAP now because I want to record the dang sound and post it now, heh.

Thanks!
J
