There are 5 speakers, two Yamaha 1500 watts. There are two speakers of the same type (i.e., NB) giving the power of a single speaker from 400 watts to 600 watts. There is a Max speaker with a power of approximately 400 watts. There is a lighting mixer and laser operation. There is an 11-input sound mixer. There is a 12-input power mixer (electricity). Selling all of them, and if you want something specific, I have no problem, as long as you are serious. ******** All speakers are working, and the remaining devices, mixers, and everything mentioned above are working, guaranteed. You have the right to inspect wherever you want. Selling is easy.
