Dumb blonde needs help with power cable matching to subwoofer


Hi! I have a buyer here for my late husband's Rythmik Audio Direct Servo Sealed F12 Subwoofer and I need to know what power cord goes with it.
(When my husband's friends were dismantling his stereo/Home Theatre system they didn't keep the power cords with the components.)
Can someone please help?

Any power cord. Look around, most guys have some of the cheap black rubber ones that come with components. Use that one. Any power cords other than the freebie black ones should be sold separately.
MC has it right. Make sure it matches, could be a two prong or a 3 prong. 
Use a power cord that you would use in your home tower computer. It has a male plug at one end and a female at the other. It is a 3 prong plug.
Look into the plug socket of the subwoofer and see the pins and shape of the socket.  As others here who have replied have mentioned, should be a standard 3 prong plug that works for computers, one up above the two lower ones.  They are readily available at Home Depot or hardware store too.
