Dumb blonde needs help with power cable matching to subwoofer

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.  

Another take on this is whether it matches may not be the only question. People into audio often use aftermarket power cords, since the cords that come with powered equipment are often inexpensive “standard” cords (typically all black with molded plastic ends).  It is possible your husband had some more expensive cords with his system and it would not be fair to you for a buyer to give you a fair price on a sub and then also receive an expensive power cord without paying a premium price for that.  I see you have been working on this for a couple of months so if you have somebody helping you with pricing I suggest sending them pictures of the power cords you have, and other cables, so you can get some ballpark pricing recommendations.

Every dumb blonde I ever knew, was too dumb to know she was dumb LOL

It cracks me up that, as in most threads, nobody reads the actual 1st post by the author. 

She said;  "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."

She had a buyer there when she asked the question. Any answers after MC, Russ and mine would be moot.

kkirk,

If all of your power cables look like standard power cords it doesn't make a difference.  If they come in different thicknesses, strange looking plugs on the end and round or flat you probable have custom power cords.  If they are custom, if you take a picture of them and send them to me I will do research for you to let you know what they are worth. Some of them can be thousands of dollars! (Not mine.;-) ) Just an offer.

First, thank you to everyone for your replies. Second, to tweak1: Thank you for the compliment! I am blonde (I’m of 100% Norwegian descent) and also fairly smart, but that’s not to say I don’t have my moments! But I thought I would get responses quicker on my post since my buyer was there & I was embarrassed I hadn’t matched up the cords yet.

The buyer was actually veerrryyy patient and we figured it out. We set aside the 5 thickest cords, then took the 2 that matched and used those. (He was buying 2 identical Direct Servo subwoofers.) The other 3 are most likely for 3 other monster (to me anyway) amps/preamps Doug had.

I was under the impression one had to be careful like you do with an AC Adapter matching input/output, amps, volts, etc. Live and learn!! Thanks again!

KK it’s just a normal IEC power cord that doesn’t use the earth.
