Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (15 Foot, Grey, Two Spades to Four Spades)

Bi-wired design: two connectors at the amplifier side, four at the speaker side. Premium terminations: a distinctive ultrasonic welding method bonds the copper wire directly to the brass banana or spade connector, eliminating any intermediate metal, compression sleeves, or set screws. Star quad cable arrangement lowers the electromagnetic field surrounding the cable for reduced interaction with other system wiring. Manufactured in Seattle, Washington, employing proprietary connectors and a Sonobond welder. The welded spade connectors have a 9.2mm opening, which accommodates almost all binding posts, and are constructed from solid sheet copper, gold-plated for corrosion-free contact
