Harmonic Technology's Pro-11 Plus speaker cable is an 11 AWG internal mono-wire single crystal cable. The Pro-11 Plus has won the Golden Ear Award from Absolute Sound and is also listed in Stereophile's Guide to Recommended Components.

A two-conductor version of Pro-9 Plus, the Pro-11 Plus accommodates systems where the speakers cannot be bi-wired. The Pro-11 Plus contains a one-inch diameter outer construction using 19 strands of individually insulated 24 gauge copper filaments, resulting in a total of 11 gauge per conductor path. This design optimizes the ratio between surface area and core size, greatly reducing the "skin" effect for high frequency detail and smoothness. Our Single Crystal construction and exceptionally high purity 6N copper allow this cable to make your system sound closer to live music.

The Pro-11 Plus is a reference speaker cable that easily beats the competitive cables in neutrality, clarity and soundstage transparency. Imaging is holographic, with inter-note silence that has to be heard to fully appreciate. The midrange is spookily real, with the full harmonic richness of a live concert. Harmonic Technology highly recommends the use of the Pro-11 Plus speaker cables for any system, as its accuracy with benefit any combination of components and speakers. It is truly a universal cable.
