Coupling Banana Plugs

Monster used to have a model banana plug called the Exterminator that had a hole on its rear to piggyback another banana plug.I still have some,but they aren't for sale.

Well I think I can answer my own question.
I just purchased a couple of banana jacks that are designed to go into a in wall type box.
One side accepts a banana and the other side is designed for bare wire , but it can accept a banana. That side has a set screw for the bare wire but it can also be used for tightening and locking the banana in place. I cut out the plastic that surrounds it.
Looks pretty cool and functions perfectly.

You can stack most banana plugs. Check out Parts Express.

Yes, but the cables I am using already have banana's attached on each end. So stacking is not an option.

What I seek is a coupler. Sort of like a RCA coupler that is used to connect 2 RCA's together, but made for banana's.

My DIY version does fit the bill, but I am surprised that there really is no commercially made product.

They still make connectors like that but they won't work in this case. Both ends need to be female.

Googling "banana plug coupler," with the quotes, returns what appear to be a number of promising choices. The most efficient way to peruse them, amidst a number of irrelevant results that are also returned, is probably via the Google Images link.

Thanks Al, The one highlighted in yellow is what my DIY looks like.
It seems all that would work on the image link that you have provided is either in China or the UK. Nothing in the USA.

OK. Since the couplers have uninsulated metal, make sure of course that the two couplers used for each channel cannot come in contact with each other, or with anything else that is conductive or grounded. You may want to wrap them with electrical tape.

Good point. I used some clear thick spiral wrap around the metal.

For your rear speakers, there's really no reason to use expensive cables. A spool of Audioquest or Monster should be all you need. Use anything more than that, and I don't think you'll be able to hear a difference.

Zd542, Swampwalker, thank you for your comments.
I had about 25 feet of Kimber 8TC and found another 18 footer used. This second set replaced a cheaper 20 foot pair.
With the cable now all the same, I found that it did increase the output and the sound quality.
