How much does a square dance speaker with wireless microphone cost?

A few hundred dollars! This depends on how many inches you use ah! Square dance some people use dual 10-inch and dual 12-inch speakers, some with internal power can be charged! Some do not take the power need to plug the power supply, most of the features are now similar, all support usb interface and plug the card, but also with audio inputs and so on. Microphone is not expensive about 100 yuan wireless microphone can be. Generally are doing business and meeting with use. I just participated in the 2015 Guangzhou Audio and Lighting Exhibition back, you said a lot of such speakers. The whole set down does not need much money, but the price is higher sound quality and quality is certainly a difference.
