In 1979 this classic design put Kimber Kable on the map and after improvements over time, is still considered the reference for affordable loudspeaker cables. Millions of feet of this remarkable cable have been sold. The construction consists of four brown and four black conductors that utilize Kimber's proven braiding technique. The aggregate wire size is two 14 awg conductors. Even the most basic systems, old and new, will benefit significantly from this legendary performer. Bass and treble frequencies are allowed their full extension, while dynamics emerge unrestrained. The 4PR is also an excellent cable for professional and studio use due to its inherent ability to reject noise in any cable length.
