Where can I find second-hand stage speakers in Nanchang?

According to relevant inquiries, Nanchang Xiangjiang Guang Cai Market has Nanchang second-hand speakers and other related items for sale.

When buying a second-hand stereo, first look at the appearance, whether the corners are broken, whether the panel is hit, and then turn it on. Don't connect the audio source after turning on the phone. Slowly turn up the volume of the amplifier. Listen to it during the connecting flight. If there is cracking sound caused by poor contact, it is best not to consider it. The potentiometer feels smooth. Listen to the horn when the volume is at or near the maximum.
