I kinda get confused about this but does frequency response and frequency range the same thing? Some people say yes and some people say both are little different. Like my speakers says that the frequency range is from 90hz to 20kHz. But Roland could off of cource said frequency response is 90hz to 20kHz right since both the same thing?

I just really need to know the truth is range and response is exactly the same thing just worded differently?
