Correct way to attach speaker wires... Wait, what!!!

the connection just needs to flow an adequate current to not create a significant resistance

the speaker is like an electric motor and needs some current to move the cone, ribbon, or panel back and forth

there are conductive liquid polymers you can use to inhibit corrosion; otherwise any connection will be fine - you are not driving an arc welder

plenty of other things ot worry about (room treatments for example)

Thanks Kenny!  I'm glad you replied since if I recall correctly you either have or had the same amp. I was pretty sure that was the case but I thought this would be a good time since I now have new equipment. 

Bare copper is bad due to oxidation. The best long term solution is a crimped on banana or spade.

Spades and screw materials should be SOFT! Cheap spades using pot metal or hard brass core are the worst. You want the spade to give and be pliable enough to give you the best contact area.

A symptom of having too hard materials is you can't finger tighten them well without a risk of them coming undone.

I think WBT has spades with spring loaded construction exactly to solve this issue.

Best,

Better to solder the connection to the spade or bananas you get a much higher contact area and it will stay secure longer then a simple crimp. Also more corrosion resistant. tin'd bare wire is also good or even bare wire. In the industrial military electronics world you would never use a simple crimped on connector unless you wanted it to fail or lose conductivity. Just my 2 cents
