Is there a way to connect to this speaker by bluetooth?In order to connect to this speaker via bluetooth, you will need to add a bluetooth adapter to your order. With that adapter, you will be able to connect any device that has bluetooth to the speaker.
Do I need a mixer or sound board in order to use these speakers?It depends of the use you want to give to the speakers. If you want to play music from your phone / laptop you just need a bluetooth to XLR adaptor.
How would I connect a wireless microphone to these speakers?Some wireless microphone receivers will let send a pre mixed signal directly into the speakers. However, we highly recommend using a mixer so you can adjust the levels of each microphone if needed.

If you want to play background music during a wedding cocktail hour, a pair of PRX 815 would be sufficient. If you want to play loud hip hop or house music, you are going to need to add a subwoofer.
