Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (50 Foot, Black, Two Bananas to Four Bananas)

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. Premium terminations: a unique ultrasonic welding process fuses the copper wire directly to the brass banana or spade connector, with no intervening metal, compression sleeves, or setscrews. Star quad cable configuration reduces the electromagnetic field around the cable for minimal interaction with other system cabling. Assembled using proprietary connectors and specialized welding equipment. Locking banana plugs provide optimal engagement between the plug and binding post; advancing the locking collar tightens the splines to the inside of the post
