The tone quality of thich membrane power amplifier I have used is not so good, but it is ok if you don't have high demand for tone quality.
Thick power amplifier tone quality is very good. I think it can protect ears. Thick membrane refers to a film layer from few microns to tens of microns formed through printing sintering technology on the substrate. Materials that makes this film layer is called thick membrane materials.
Thick power amplifier tone quality is very good. It is widely used in high-end multimedia classrooms, training rooms, small meeting room or other simple amplification occasions. The microphone can be directly connected to frequency shift for power amplifier and can also effectively inhibit the whistle of microphone to loudspeaker box and support the background music for amplification.
