Proper way to make in wall binding post connection

[bbull@pathfire.com]

I've just finished running speaker wire through my walls and was
wondering what the proper way to connect the wire to the back of the
binding posts is. The instructions say to:
1. strip 3/8" of the wire
2. unscrew the set screw
3. insert the wire into the rear opening of the module
4. tighten the set screw

I don't quite understand how this will make a good connection.
Should I solder them in instead?

The screw makes contact with the binding post - it's fine.

The screw and post both conduct electricity. It goes from the wire, to the
screw and post, to the other side. heh

Only if you want to melt the plastic.

Contrary to wild claims made by Monster Cables and the like, you rarely need
soldered contacts (or gold, or silver, or bullshitanium) in regular wiring.
I solder some, not all, of my banana plugs, but only because the plugs
themselves were cheaper by far than Monster or other fancy brands, the local
stores were out of cheap screw in plugs, and because the speakers vibrate,
which over time can cause loose connections.

There's nothing wrong with screw in, or even friction connectors. Most of
your house is wired the same way.

Thanks for the replies.

Would it make any difference if I tinned the wires before inserting
them into the binding post? Or, would that just cause unnecessary
oxidation?

Tinning it will tend to reduce the conductivity and the amount of surface
area that is in contact between the wire and the other conductors in the
plug, so it's not what I'd recommend. If you're really concerned, places
like Parts Express online have conductive grease that is useful. I have some
of it, it's a silver particle bearing grease, you smear it all over the
wire, crimp or screw down the connector to it, and smear some more over the
outside. It keeps air off the connection and prevents oxidation. You don't
want to smear so much on it provides a signal path between sides though (L
and R). You can also just crimp/tighten the nuts and wire down tight, and
then take any kind of thick grease, and smear it over the outside to protect
the joint from oxidation. Commonly done in marine and automotive
environments.

another great thing is to get a wall panel that has binding post connectors
on BOTH sides.
Banana plugs fit in both sides

That's a good idea... IF your wall has the clearence to accept such a wall
plate! (I know a lot of residential homes don't have the clearence...
especially when you have a pile of cables to connect to the plate.

It wont make any difference but it will make for a neater installation, I'd
rather put some nice banana plugs on, though
