They go $355.00 on audioadvisor, I am asking only $200.00. Analysis Plus is uniquely qualified as an authority on speaker cable design. The Detroit-based company earned its reputation testing and analyzing cables for leading cable manufacturers whose names you'd recognize in a flash. After examining the best, Analysis Plus decided it could do even better by developing its own proprietary hollow-oval conductor design. Why the unique conductor geometry? Mark Markel and Qinwei Sun, the chief engineers at Analysis Plus, determined that round cable used in conventional speaker cable designs has high levels of current bunching, skin effect phenomenon, and other frequency characteristics that degrade signal quality. Rectangular conductors were a little better, but these suffered high electric field values caused by sharp corners which can also cut into and injure the dielectric when the cable is flexed. After many computer simulations, Analysis Plus found that a hollow oval cable was the best design due to its minimal change in resistance with frequency, plus other benefits. The company chose a flexible, braided conductor rather than the conventional solid conductor, which is susceptible to kinks and deformations with resulting signal degradation. A unique woven pattern places every wire statistically as close to the return current as every other wire for evenly distributed high-current density and superior sound. Oval Twelve speaker cable from Analysis Plus is a 12-gauge cable constructed using the company's exclusive hollow oval cross-section conductor array. Oval Twelve offers 90% of the sonic benefits of the company's acclaimed Oval Nine cable, but at a much lower price. Oval Twelve incorporates a patent-pending woven design in which every conductor wire is statistically as close to the return current as every other wire. The result is evenly distributed current density that adds up to better signal transfer than conventional solid-conductor cable designs. Oval Twelve is handcrafted with special high-purity oxygen free copper combined with a computer-matched dielectric to give the best possible performance. Oval Twelve is factory terminated with crimped-on 1/4" gold-plated spade lug connectors.
