- Reference copper
"A painstaking precision product for an exacting application." These were the words on the very first Kimber Kable brochure and they ring true to this day. The exacting application is the highest level of music reproduction in your space. We were not satisfied with bringing the experience to your home, we wanted a product that was capable of taking you to the performance. The KS6063 is the Kimber Select reference copper(solid core and stranded) loudspeaker cable.
