Understanding Amplifier Power
Amplifier power is measured in watts (W) and is a measure of the amplifier’s ability to drive a speaker or other load. The power rating of an amplifier is typically specified as a Root Mean Square (RMS) value, which represents the continuous power output of the amplifier. RMS power is a more accurate representation of an amplifier’s power output than peak power, which is the maximum power output of the amplifier for short periods.
The Importance of Matching Amplifier Power to Speaker Sensitivity
When choosing an amplifier, it’s essential to match the amplifier power to the speaker sensitivity. Speaker sensitivity is a measure of how efficiently a speaker converts power into sound. A speaker with high sensitivity requires less power to produce the same sound level as a speaker with low sensitivity. If an amplifier is too powerful for a speaker, it can lead to overdriving the speaker, which can result in distortion and potentially damage the speaker.
The Dangers of Excessive Amplifier Power
Having too much amplifier power can be detrimental to your audio system.
