THIS IS A SPEAKER CABLE This is the Alpha Core Goertz: MI 2 Veracity Biwire Speaker Cable (Pair) Alpha Core Goertz makes cables that offer almost zero distortion. Very effective over long runs. Very effective at combatting RF, and EMI interference and high-frequency roll off. Low inductance, and impedance. Flat design, allows for added flexibility in broad applications. The patented Goertz MI cable, invented by Ole Goertz, a Danish electronics and audio engineer, eliminates distortion between amplifier and loudspeakers. Patented in 20 countries, Goertz wire is flat by design. It’s form follows function, in the best design tradition. We set out to create an electrically correct pathway between amplifier and loudspeaker, which required replacing typical cable psuedo-science with solid physics. Research showed that the perfectly flat shape, with minimum space between conductors, was the best way to achieve this. But developing such a wire is a different proposition. Many audio companies do not even manufacture their own wire; packaging and marketing the products of others instead. As a primary maker of high-tech laminated conductors for industrial electronics applications, Bridgeport Magnetics Group was uniquely suited to transform the promising Goertz design into reality. Using the dielectrics Polyester Terapthalate and Teflon applied around each solid rectangular conductor, we achieved an extraordinarily thin profile between the two stacked wires. To provide maximum protection while maintaining thinness, the cable sandwich is then sheathed in tough, high grade polymer. The result is a wire with a characteristic impedance that closely matches the impedance of loudspeakers. Bridgeport Magnetics Group’s Goertz MI wire presents 2 to 4 ohms characteristic impedance as opposed to the 50 to 200 ohms presented by even the most expensive speaker cables. This correct electrical matching results in improved stereo imaging, better clarity, less high-frequency roll off and better low frequency definition. Goertz Improves all Frequency Ranges:LOW . . . MIDRANGE . . . HIGHThe degree of distortion along a loudspeaker cable depends on its resistance ( R ), inductance ( L ) and capacitance ( C ). Resistance is dependent on length and conductor cross section. A low resistance provides superior damping between the amplifier and the speaker diaphragm, governing its ability to convey a true, powerful bass and lower mid-range. A high cable inductance causes loss of signal strength towards the high end of the audible range (roll-off). It also causes frequency dependent phase-shift which disturbs true stereo imaging. The square root of the ratio L/C is termed Characteristic Impedance, and is a quality inherent in a cable, dependent on its geometry and materials, but not dependent on its length. Goertz Virtually Eliminates MismatchThe characteristic impedance of the Goertz MI cables in the order of 2 to 4 ohms closely matches the impedance of loudspeakers. Almost all other speaker cables have characteristic impedance ranging from 50 to 200 ohms, a mismatch which causes distortion due to signal reflections. Impedance matching primarily improves the clarity of the highs and upper mid-range, but many users have also experienced improvements in the lower mid-range. The cause seems to be that signal reflections caused by impedance mismatch enter the feedback loop of many amplifiers and disturb their ability to reproduce faithfully even lower frequency signals. Thick on Benefits, Thin as a PennyThe low inductance and characteristic impedance of Goertz cables are due to their flat construction and the nature of their insulation and jacketing material. The configuration places the heavy, solid conductors only 0.003 inches apart. The cables are 0.4 or 0.8 inches wide, and only 0.04 inches thick. As thin as a penny. Perfect for Home TheaterGoertz MI speaker cable and interconnects are perfect for home theater applications. Due to the low inductance characteristics, Goertz audio products are ideal for long runs. No more positioning your equipment based on the limitations of your cable system. Dolby Digital home theater design requires full range audio frequencies be sent to rear speakers; Goertz cable allows extreme accuracy at any length. The space ratio, the relationship between conductor cross section, is about 50% in Goertz MI cables versus 5-20% in most other speaker cables. In other words, Goertz cables pack heavy conductor cross sections into an extremely slim package yielding greatly improved highs and mid-range, plus a truly powerful bass. Thanks to the flat construction and extreme compactness, they can be drawn anywhere and routed under thin carpets and wallpaper. If desired, paint with oil or water based paint. Do I Need a Zobel Network?The Zobel Network is a tiny filter installed in each speaker cable to stabilize the capacitive load the amplifier sees when using these cables. The Zobel Network is required on Alpha Core Goertz speaker cables that are 10Ft and above or when the cables will be used with OTL amps. The Network is sonically invisible and operates in parallel, which means its not in the signal path and does not affect sound quality.Please note these are a Biwire pair with the Silver Spades upgrade. Also included Cables pulled from a working system, in very good working and cosmetic condition -- see photos. Photos are actual item in this listing.

Selling a 4 FT pair of Alpha Core Goertz MI-2 Veracity flat cables in fantastic condition. Perfect for a high-end bookshelf system. (I used them with a pair of B&W 805Ds.)These are the bi-wire version - each channel has double the cable.Amp side has a pair of rhodium spades, and the speaker side has 2 pairs of silver spades. Cable is made if high purity OFC.The equivalent gauge is 7 AWG (10AWG in parallel). Goertz flat loudspeaker cables have exceptionally low inductance compared to zip cord because the conductors can be placed extremely close together. Inductance is what causes measurable deviations in frequency response as a function of your loudspeakers natural impedance vs frequency curve. The deviations can be a fraction of a dB (or more) and occur within the audible range (20hz-20khz). This is well characterized in older peer-reviewed papers published in the Journal of the Audio Engineering Society. If you are interested in speaker cables supported by scientific research, as opposed to wild manufacturer claims, these are your cables.
