Blue Jeans Cable Canare 4S11 Speaker Cable, with Welded Locking Bananas, Conventional (Non-Bi-Wire) Terminations, Grey Jacket, 10 Foot (Single Cable - for one Speaker); Assembled in The USA
BJC Speaker Cable, made with 4S11 and Welded Locking Banana Plugs, conventional (non-bi-wire) terminations At Blue Jeans Cable, we were never happy with the conventional methods of attaching speaker cable to banana plugs. Setscrews are fine, but lack pull strength; compression connections are never as strong as they look like they're going to be; and solder, on large high-mass connectors, is slow going and tends to cause a lot of insulation meltback. Our solution: ultrasonic welding. Our Sonobond Ultrasonic Welder (made in West Chester, PA) welds the copper wire to the brass banana plug body without the excessive heat associated with conventional welding, fusing copper to brass in a tight, strong, low-resistance, reliable connection. Conventional (non-bi-wired) Terminations: This cable is made with two banana plugs on each end, for conventional speaker wiring. If you're looking for a cable with two on one end and four on the other for bi-wiring, we offer those as well -- search our listings.

There's no attachment mechanism for the wire -- no set screws, no clamps, nothing but a channel for the wire to sit in. The Welder This is one of our Sonobond Ultrasonic Welders, in our Seattle shop. Unlike heat-based methods of welding, it drives a large amount of ultrasonic vibration into the junction between the wire and the plug, fusing them together. The Weld Here's a plug body after welding. The surface structure of the wire breaks down during welding, allowing dissimilar metals to fuse. The resulting weld has extremely low contact resistance and high pull strength. The "Locking" Feature The outer collar of the banana plug is threaded. It should inserted into the binding post with the collar "backed off" from the plug end (top image). When the plug is in the binding post, simply turn the locking collar clockwise (bottom image) and it pushes a central pin forward, expanding the splines for a firm engagement in the post. Read more
