I have been asked to post some instructions on how to install the Electra tube connectors.
If you have not seen the Electra tube connectors then follow this link to the Electra Cable website and read all about them: http://www.electracable.com/tubeconnector.htm
These things beat any binding post ever made.
They install faster and easier than any binding post as well. Just follow these step by step instruction and you'll see just how easy it really is.
First you'll need to drill a 7/16" hole in your enclosure. These also work just as well in any enclosure thickness so no problems even with thick or multilayer walls.
Then feed the wire through the hole until it pokes out far enough for you to get a hold of it. 2 to 3 inches is fine. And slide your heat shrink on before you forget it.
Now a very important part to remember is to take the male stud that comes with the tube connectors and insert it into the end of the tube connector. This gives the internal wire a stopping point when you insert it. And the whole idea behind the tube connector is to get tip to tip contact from the internal wire to the speaker wire.
Now that you have a stopping point you can insert the internal wire from the speaker into the tube connector until it touches the stud inside of it. Then you mark its depth and strip it that far back.
Insert it and note that the insulation comes to the end of the tube connector. Now you are ready to crimp it.
When you go to crimp it make sure that the part of the crimping tool that pokes up goes into the back side of the tube connector because there is a slit in the tube on the front side.
Then crimp it right in the middle of the end of it.
Now note how it looks on the back side.
And the front side.
Then you solder it to seal the opening from any air passage.
Then slide the heat shrink down over it and seal it.
Now you can add just a slight amount of sealer around the outside of the tube connector. I use clear Silicone myself. Then press it into the pre-drilled hole. If you have to lightly tap it in with a small hammer that's okay too. It will smoothly drive in with very light taps.
Now wasn't that fast and easy?
And a bonus is that it sounds better than a binding post.

"Repeatable and easy to detect differences", even on one of our budget level kits and with an inexpensive system.
