If an amps frequency response is 20 to 20K Hz, and some rife frequencies call for anything below 20hz, how can the amp reproduce that frequency?
A.Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency. The amplifier will produce the lower frequencies, just not 3dB. The difference is not enough to matter.
