Reply to Help with B&W Speakers to S4 setup

Hello guys, I'm new and starting out, my current setup now is, S4, Macbook, ipad2. My main question is the speakers/RCA. I have 2 speakers (handed down) I'd like to use, was curious how would I be able to connect them together, the speakers are B&W DM630's (mid 90's production) they have 2 high (pos/neg) and 2 low (pos/neg) but I'm unfamiliar with their connection type, speaker wire, RCA, or perhaps another?

They have never been used before, practically new, I'm not an audio expert but I would assume I would need an AMP or an adapter from speaker to device/AMP to RCA to S4? Any help would be greatly appreciated thanks.

Edit: Can anyone tell me what type of cable that goes to these speakers? xlr/rca/speaker wire?
