If the speakers have 2 wires coming out of each then connect them to the speaker terminals on the studio standard. There is a positive (red) and negative (black) for each speaker. If you are not sure which is which you can connect them both the same way and play some music with a strong kick drum. This will make the woofer move out when the kick sounds if they are correct. Reverse both if not.
If the speakers have an RCA jack on them you will need speaker wire with an RCA at the speaker end (positive it the pin that sticks out) and bare wire at the other end.
