Question About Frequency Response

In all my reading about different amps and speakers I'm wondering about differences in frequency response between amps & component speakers. For instance, I'm looking at component speakers up front that have a frequency response of 60hz to 30,000 hz and a Class A/B amplifier that has a frequency response of 30 to 12,000 hz. The amp has a THD of 0.02% and matches the speakers perfectly at 100W rms.

I know that the human ear can only hear in certain ranges so can someone explain to me if there would be a problem combining these two, why, and if yes, should I be looking for a matching frequency response for both?

Thanks for your input!

double check the amps freq response please what you wrote is not very good, the common maximum limits of human hearing is 20 Hz to 20,000 Hz

I tend to ignore most specifications because I find them irrelevant in many cases because they are not precise measurements, nor are the tests to derive the measurements.
A frequency response rating of 5-40Khz is more vague that a rating of 20-20Khz +/-3dB
Now on amplifiers those tests are derived using a resistor, which is a constant resistive load, unlike a speaker which "reacts" and is a reactive load, whose resistance/impedance changes as it moves up and down.
I am sure that amplifier will drive the speakers fine. The reading for the amplifier may be inaccurate unless it's a dedicated subwoofer amplifier.

Yeah...something is wrong there (maybe a typo), virtually every modern amp can do 20hz-20khz unless it's a dedicated sub amp which is usually 20-200hz or so.
