Thank you and have a nice day. A speaker refers to a device that converts an audio signal into sound. In layman's terms, it means that the speaker box or the subwoofer box has its own power amplifier. After amplifying the audio signal, the speaker itself plays back the sound to make the sound louder. The speaker is the terminal of the entire sound system, and its function is to convert the audio energy into the corresponding sound energy and radiate it to the space. It is an extremely important part of the audio system and is responsible for the task of converting electrical signals into acoustic signals for direct listening by human ears. How long is the life of the speaker, this is a question that many people are concerned about. It should be said that 15 years of normal use is absolutely no problem. If it is well maintained, it will take even longer. For example, Brother Sanxian, your Jinlang 907Be, as long as it is well maintained, Guarantee that you will have no problem using it for 20 years. There are N pairs that have been used in my home made speakers for over 15 years and are still in normal use. But why do some speakers get damaged after a few years of use? This has a lot to do with use and maintenance.
