Question for users of bare wire ends speaker cable

Yes Sugar, indeed they can and that's what I'm using. I soldered them with RadioShack silver solder and threaded them through the binding posts. Still you will have to clean it often but with much better convenience.

Ditto!

I am not a solder expert. I should heat the wire with the iron and apply the solder to the heated wire, correct??

Does cleaning them often just mean cleaning the soldered ends, or are you guys cutting them off and re-soldering?

Put some solder on the iron first and use the solder blob to heat the wire (better heat transfer ... faster results). When the solder begins to flow on the wire add more solder until the wire is completely coated. You'll know when the wire's hot enough because surface tension will draw the solder onto the wire.

To clean I would just wipe with electrical cleaner, or rarely just resolder with some fresh solder. I wouldn't cut the ends off .... but then I'm a cheapskate.

First spread some flux on the wood panel that you will be using for soldering (some small plywood piece should work)
with hot iron melt the flux and dip(or thread through) your bare wire through the flux equally spreading it over the wire surface with the hot iron.

Than(if you're using a RadioShack silver solder) cut approximately 1 ring of solder and melt it inside the spreaded flux and thread through the bare wire equally spreading solder over the bare wire surface.

Define for yourself how often you need to clean soldered ends(and sometimes binding posts as well) simply by checking it's surface once in a while starting from once per week.
