Superb Kimber Bifocal XL speaker cable pair. 13 ft. length. These cables were custom made by Kimber specifically for bi-amping. The stock BiFocal cables have a common set of connections on the amp end and separate hi/low connections on the speaker end for bi-wiring only. These cables have separate WBT 0645 connections on both ends of the cable so they can be used for bi-amping, not just bi-wiring. There is a significant sonic advantage with bi-amping over just bi-wiring. You can see the 4 connections in the photos. These cables cost over $4,000 new and they are in excellent condition.
