Are you considering to pick a couple of wireless loudspeakers? You may be confused by all of the technical jargon utilized by suppliers to show the performance of their models. Wireless loudspeakers come in all different shapes and sizes. Selecting the correct model may often be difficult . One of these is the built-in power amp. Usually the distortion of the amp will be larger the more output power it supplies to the speaker. This tone is a pure sine wave signal with minimum distortion. Distortion, though, is usually dependent on the signal frequency. The second contributing factor is the speaker element itself. The majority of loudspeakers utilize a diaphragm type driver which is driven by a voicecoil which is suspended in a magnetic field. Nonetheless, this movement is not perfectly linear. This results in the audio being distorted by the speaker element itself. On top of that, there are other contributing factors. Depending on the material used to manufacture the speaker housing, there are going to be vibrations or enclosure resonances. These normally depend on the sound pressure level, the enclosure shape, the housing material as well as audio frequency. As a result extra sound distortion will be brought on by the box itself.

The audio analyzer will calculate the amount of higher harmonics or distortion. Typically 900 MHz FM transmitters have among the highest amount of distortion. Typically these transmitters operate at 2.4 GHz or 5.8 GHz.
