Why it matters

Watts help set limits.

Amplifier watts describe how much electrical power an amplifier can deliver under stated conditions. Speaker watts usually describe heat handling, and sometimes a recommended amplifier range. Neither number proves clean output by itself.

How it works

Power depends on voltage and load. In a simplified resistive case:

More wattage can increase maximum output, but loudness also depends on sensitivity, distance, room gain, enclosure behavior, distortion, and the frequency being played.

Common mistakes

Simple example

Amplifier An amplifier takes a small audio signal and delivers a stronger voltage and current signal to a speaker. The speaker load, power supply, gain, and protection limits decide how hard it can work. Amplifier parameters Amplifier parameters explain what load the amp can drive, how much clean output it can deliver, how much gain it has, and where it clips, heats, or protects itself. Impedance Impedance is the electrical load the amplifier sees. It changes with frequency, so a speaker marked 8 ohms is not 8 ohms everywhere. Sensitivity Sensitivity tells you how loud a speaker gets from a known input. It helps estimate output, amplifier needs, and how well drivers will match.
