Yes, the low E string on the bass guitar is 41.2Hz, and the low E string on a regular guitar is 82.4Hz, assuming normal tuning.
I would generally agree with Onhwy61 about the general frequency ranges. Probably most people will have slightly differenct numbers, but I'd suspect that most would agree with those general ranges.
Regarding your question as it relates to "fullrange" speakers, the speaker will actually respond below the rated frequency for at least a few Hz, and maybe even 1/2 an octave, depending on the design. It doesn't just "cut off" abruptly, but rolls off fairly quickly. So even if the bass player tunes down a step, you'll still get his open low string pretty well. The real weakness in the low bass shows up with organ music or deep electronic synthesizer notes. To be honest, with my Lowther EX3 drivers in modded Voigt Pipes, I never feel like I'm missing anything with the music that I normally listen to. I don't use a subwoofer, and I play pop, rock, jazz and classical.
