What is speaker sensitivity ?

Speaker sensitivity is most easily defined as a speaker’s ability to convert power to sound or how effectively a speaker converts power, watts into sound decibels. Sensitivity isn’t necessarily used to measure loudness it’s more used to measure the efficiency of the speaker and yes the higher the number the better so 92 decibels are higher is ideal but try to remember and be able to differentiate that sensitivity doesn’t mean quality and a low sensitivity doesn’t it’s a bad speakers it’s just less efficient there are plenty of high-end pro speakers that have a very low sensitivity around the 84 decibel range because they require a lot of power so it has nothing against the quality of the speaker it’s all about efficiency. But if you’re just rocking a simple system with a low powered amplifier it’s  really good spec to go by and in this instance efficiency is the amount of power going into the speakers being converted into sound. Sensitivity is measured from the amount of sound output from the speaker with one watts of power input from an amplifier it’s about how high the volume on your amplifier needs to be to make your speakers work at their best, the higher sensitivity of the speaker the louder it will play with a certain amount of wattage as opposed to a low sensitivity speaker.  For a speaker with a sensitivity let’s say 82 decibels the higher the wattage and louder you go the harder it is for that speaker to keep up with say a speaker that has a sensitivity of 92 decibels. Highly sensitive speakers require less power to drive a sensitivity measurement of about 88 decibels is about average anything below 84 decibels is considered low sensitivity and again it’s all about efficiency and how much power you need for your speaker to perform it’s best.
