Many people mistake a speaker amp’s power rating or wattage for its loudness.

Doubling the power output of a speaker does not double the speaker’s maximum volume.

What Is Speaker Efficiency?

For example, a speaker’s efficiency is typically measured with a microphone placed one meter from the speaker.

The output level that results is the speaker’s efficiency rating.

Dynamic Range

Music is dynamic in nature.

The best way to understand audio dynamics is to listen to live, non-amplified music.

This range in volume is known as dynamic range, the difference between the softest and loudest passages.

A cymbal crash is another example of the difference between dynamics and amplification.

The ability of the receiver to deliver bursts of power in brief spurts is important for accurate sound reproduction.
