How to Connect Cobalt Cables Speaker Cables?

Hello All,
Please help out a female audiophile with no brains. I bought a beautiful set of Cobalt Cables speaker cables used off the Internet. They are terminated on both ends with what look like RCA ends. I cannot figure out, for the life of me, how I hook these ends up to my speakers or to my amp.

Can anyone advise on this?

I would really appreciate the help.
Are you sure they are not banana plugs, as shown here, rather than RCAs?

If that's the case, and your amp and speakers do not accept banana plugs, Google "banana to spade adapter" (with the quotes) and you'll probably find something suitable.

BTW, although it undoubtedly has no relevance in this case, I'll mention that 40 or 50 years ago or thereabouts there were some passive speakers manufactured that were connected to via RCAs. (Active speakers, containing their own amplifier, are of course often connected to via ordinary RCA interconnect cables).

Al, it had indeed slipped my mind about powered speakers. Had no knowledge whatsoever about the use of RCA-type speaker cables from back in the day :) And a good suggestion to make sure they're not bananas, which is indeed what Cobalt offers.

If they are indeed banana's you may have to remove the safety plugs that many speaker makers put into the end of the binding posts.
I think it would be a good idea if the OP can post a picture of the cables and list the system.
