If you see a "frequency response" with tolerances, such as 70-5000Hz +/-3dB,
you know the frequency will stay within those tolerances over that range
at full rated power. Outside of that range you probably get output but you
don't know what it will be.

If a frequency range is given without tolerances it is meaningless except
in that it tells you to avoid a vendor who gives fake numbers.

In your experience, would a guitar speaker (not bass guitar speaker) be
capable of producing low frequencies around 40 Hz at any output? I
ask because I was privy to a discussion where it was claimed that 1) they
don't have the excursion needed to produce frequencies that low and 2) the
wavelength comes into play; speaker excursion can't deal with waveforms
that long. There was also mention of guitar speaker cabinets being designed
for mid-bass on up to around 5 kHz, the implication being that they likewise
aren't designed or capable of reproducing frequencies that low.

Almost ANY speaker can reproduce 20Hz. Almost none can do it at a level
you can hear or feel. The excursion is NOT simply a matter of frequency,
but frequency AND input power. At *very low* power levels there is no
problem with almost any LF speaker following a 20 Hz waveform, but the
SPL output may be low to unmeasureable! Your discussion friends simply
didn't understand all the variables.
