I will shed light on the meaning of this expression and additionally offer a few recommendations on how to interpret it whilst looking for an amp.

Consequently the frequency response provides a significant clue concerning whether a specific amplifier might be suitable for a specific use. This range is specified by showing 2 frequencies: a lower and upper frequency. You need to go through the specifications a lot more meticulously to be able to adequately interpret them.

They push the lower frequency and higher frequency to where the amp barely provides any kind of gain. A complete frequency response chart, on the other hand, will show whether or not there are any peaks or valleys and also show the way the frequency response is to be interpreted. You may also want to demand a phase response chart that offers vital hints in regards to the sound quality.

The fact is that a large number of small stereo amps are going to function in a different way with different loudspeaker loads. This is due to the fact that different speaker loads will cause changes to the behavior of the output power stage of the amp.

This change is most detectable with many digital amplifiers, referred to as Class-D amplifiers. Class-D amps have a lowpass filter inside their output as a way to suppress the switching components which are created through the internal power FETs. If not developed properly, this method may cause instability of the amp though.
