Check the magnetic shielding effect of the Wholesale TG166 speaker. Since the color display is the most sensitive to the interference of the surrounding magnetic field, you can check the magnetic shielding effect of the speaker as long as the speaker is close to the display. If the image is distorted when the Wholesale TG166 is close to the monitor, it means that the magnetic shielding effect of the speaker is not good.The tightness of the speaker directly affects the low-frequency response index of the speaker, so you should also pay attention to checking the sealing performance of the Wholesale TG166. The better the tightness of the speaker, the better the acoustic effect. To check this indicator, you can approach the port with your hand when the speaker is working. When the sound of Wholesale TG166 is a drum sound or explosion sound, there should be obvious air rushing out or inhaling in the inverter port. The more obvious this feeling is, the better the sealing performance of the speaker is.
Listen carefully to the Wholesale TG166, check the maximum undistorted power of the speaker, select a familiar song to play, and adjust the volume to the maximum but the sound is still undistorted. At this point, it is the maximum undistorted power of the Wholesale TG166 speaker. If you think this volume is enough to use, it means that this speaker is suitable.
