In that case, then yes, that speaker is active. (it has a built in amp) To connect it up to the mixer, you will need one of these -

Sorry to be a pest, haha. But would you be able to tell me what to use to connect my MacBook Pro to the mixer? It's a 2015 model with retina etc. I would be using the mac as an input for music, mic as an input for vocals and obviously the speaker as an output.
Thanks again, Peter
