Before banana plugs and spades, every speaker was connected with bare wire, and it still works perfectly today. A bare wire connection is free, universal and reliable, as long as you strip and clamp it correctly. Here is how to do it right.
Bare Wire Speaker Connection: The No-Cost Way to Hook Up
Quick Answer / Summary: A bare wire speaker connection attaches the stripped, twisted end of the speaker cable directly to the terminal, with no plug. It costs nothing and works everywhere, but the wire must be stripped cleanly and clamped tightly to avoid shorts.
What a Bare Wire Connection Is
A bare wire connection is simply the stripped end of the speaker cable clamped directly into the terminal, with no connector in between. The copper strands themselves make the contact.
Copper straight to terminal
It is the most universal connection because every speaker terminal, binding post or spring clip, accepts bare wire. It is also the cheapest, since there is nothing to buy.
The tradeoff is convenience and neatness: bare wire can fray, oxidize and short against a neighbor, and it is slower to connect and disconnect than a plug.
Preparing the Bare Wire
Strip about half an inch of insulation from each conductor using wire strippers, taking care not to nick the copper strands. Nicked strands break easily and weaken the connection.
Strip and twist
Twist the exposed strands tightly between your fingers into a compact bundle. A tight twist makes the wire easier to insert and reduces the chance of a single strand poking out.
Identify the polarity of the two conductors using the marking on the cable, and keep the marked side as positive at every terminal.
Connecting to Binding Posts and Clips
For a binding post, loosen the collar, insert the twisted wire through the side hole or wrap it around the post, and tighten the collar down firmly. No copper should be visible past the post.
For a spring clip, press the button, insert the wire into the slot, and release so the spring clamps it. Check that no copper sticks out the back of the clip.
For a screw terminal, loosen the screw, place the wire under the plate, and tighten the screw. Keep the wire from spreading under the screw, which can push strands toward the other terminal.
Avoiding Bare Wire Problems
The two classic bare wire mistakes are leaving stray strands that short against the next terminal, and under-tightening so the wire slips out. Twist well and clamp firmly to avoid both.
Bare copper oxidizes over time, raising resistance at the contact. If a connection dulls, re-strip a fresh half inch and reconnect for a clean surface.
For a permanent, rarely touched connection, bare wire is perfectly fine. If you reconnect often or the terminal is tight, upgrading to banana plugs is worth the convenience.
Bare Wire vs Plug Connections
| Attribute | Bare Wire | Banana/Spade Plug |
|---|---|---|
| Cost | None | Small |
| Universality | Fits everything | Needs matching jack |
| Neatness | Can fray | Tidy |
| Reconnect speed | Slow | Fast |
| Oxidation risk | Higher | Lower |
Real-World Application Scenarios
A user strips and twists bare wire to connect bookshelf speakers to a receiver, clamping it into the binding posts; another uses bare wire in spring clips on a budget system; a third re-strips a tarnished connection to restore clean bass.

Frequently Asked Questions
How do I connect bare speaker wire?
Strip about half an inch, twist the strands tightly, and clamp the wire into the binding post, spring clip or screw terminal, keeping polarity consistent.
Is bare wire speaker connection good?
Yes, a clean, tightly clamped bare wire connection is electrically excellent and costs nothing. It just needs care to avoid stray strands and oxidation.
Do I need banana plugs instead of bare wire?
Not for a permanent, rarely touched connection. Banana plugs are mainly a convenience for frequent swaps and for tight terminal rows.
Why does my bare wire connection sound dull?
Usually the wire has oxidized or loosened. Re-strip a fresh half inch, twist tightly, and re-clamp for a clean low-resistance contact.
