In the speaker Wholesale TG182 from China, the size of the device's electro-acoustic or acousto-electric conversion capability is called the device's sensitivity. Regarding active speakers, sensitivity refers to the magnification of the internal amplifier and the sensitivity of the speaker combination. The loudspeaker with a large magnification is connected to a small audio output power such as a Walkman and other low-power audio sources. Regarding the Wholesale TG182 passive speaker, the sensitivity refers to the sound intensity generated at 1M when the speaker combination in the power amplifier system gives a 1W 1000Hz signal to the speaker. Sometimes some audio systems are forced to reduce sensitivity for the sake of sound quality and operational stability.

The sensitivity of the Wholesale TG182 speakers is probably the most misunderstood of the various common indicators. Historically, the amplitude-frequency response of a loudspeaker has often been reduced to a single value, known as sensitivity. This is the source of misunderstandings. Some people will think that this value indicates the loudness of Wholesale TG182 from China when reproducing a signal; some people will think that the time-division loudness of two speakers with the same sensitivity when reproducing the same signal is the same. Both views have limitations.
In fact, the sensitivity of the Wholesale TG182 speakers can only reflect the sound pressure level of the speakers when they are only for signals with specific bandwidth and spectral content. Bluetooth speakers are recommended. If two speakers Wholesale TG182 from China with the same sensitivity index have different frequency responses, the output sound pressure level may be different when replaying the same signal.
