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?

That is why bandwidth is nice. The less phase shift, the better the imaging. Phase shift is caused by group delays that in turn are caused by a rolloff in the equipment. They can have artifacts to 10x higher than the low frequency rolloff, and 10X lower than the high frequency rolloff. This is less of a problem in speakers than electronics, but its still an issue.
