How Much Are You Missing From 20khz to 45khz?

.
I've seen speakers rated at 20khz on the top end and those rated at 45khz on the top end. All other things being equal, is that a big audible difference in a speaker?

I think that it is necessary that speaker response extend at least to 20kHz and have a smooth, well-behaved rolloff above. 12-27-12: Don_c55: Kr4 Do you hear any difference between a CD and SACD? I do but I doubt that it has to do with FR. For example, at an audio show, I was able to pick out the addition of an ultra-tweeter that was effective only above 20kHz even though I have audiograms which show that my hearing at 20kHz is more than 20dB from reference.
