Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The terminations utilize a distinctive ultrasonic welding method that bonds the copper wire directly to the brass banana or spade connector, without any intervening metal, compression sleeves, or setscrews. Star quad cable design minimizes the EM field surrounding the cable for less interaction with other system wiring. Assembled in Seattle, Washington, employing proprietary connectors and a Sonobond welder. Locking banana plugs and gold-plated copper 9.2mm spades ensure secure engagement at all amplifier and speaker connection points
