Speaker wire consists of twisted copper strands, around AWG 22 thru 10. As good consumers know, one must consider resistance when wiring speakers. How do the wire terminations contribute to the circuit's resistance? Two questions:
1) Quantitatively, is any non-negligible contact resistance is added by the wire connections? Loose (low surface area) connections vs. tight (high surface area) connections?
2) If one were to cut the wire and leave only one tiny copper thread of length 1cm, and screw it down at the speaker post.... would this add significant resistance?
