Douglas Connection Alpha Bi Amp Speaker Cables



Douglas Connection Alpha Bi Amp Speaker Cables.  Base Price is for one 6′ cable with out connectors. Other lengths are available.  Made with the Finest 4 conductor OFC cable by Furutech, Our Douglas Connection Alpha Custom Made Bi Amp Speaker Cables feature Furutech 4.1T 13 AWG separate conductors for treble and bass which maximize the delivery of the different ranges of signal. From the drop down menus, please select the cable length you need, and choose connectors for amp end, and speaker end.  These are Bi-Amp cables and the prices shown in the drop down menus are for 2 pair of connectors on each end of your cable.  You will also need to select the free end length you require.  Free end length is the distance between where the individual conductors exit the main cable to the connectors.  Please enter the number of cables you need.

These cables are totally assembled by hand right here in the USA, by a small family business.  When making your Cables each conductor is stripped, then cleaned and preserved with Deoxit.  Depending on the connectors you choose, we then crimp or use setscrews to affix the bare wire inside the connector, which makes far superior surface contact.  No solder is used in the construction of these cables.

ALL metallic parts used in Furutech products go through the Alpha Process treatment to keep all connectors, conductors, and metal parts in a perfect stress-free, stable and highly conductive state.

The treatment begins during the manufacturing process with a deep, conditioning cryogenic freeze of all metal parts. Using high-end refrigerants — liquid N2 or He
– Furutech achieves temperatures of between -196 to -250C. The treated parts actually change their molecular structure at these extremes of temperature relieving internal stress. The molecules bond together more tightly and the overall structure becomes more stable. This improves electrical conductivity and so power and signal transfer.

Step two in the Alpha Process exposes these same parts to the patented Ring Demagnetization treatment. Ordinary high power magnets used for this purpose often increase magnetization effects; they leave some areas more magnetized than others. Just like a CD spinning over a fixed magnet; when the CD stops the area above the magnet is still exposed to the magnetic field causing audible effects. This patented process uses controlled attenuation to completely eliminate magnetization for immediately more vivid and colorful improvements. Ring Demagnetization further enhances conductivity of all treated materials. The patent holder for this treatment is Sekiguchi Machine Sale Co., Ltd. in Japan; Furutech are licensed users of the technology.

The Final Result The 2-Step Alpha Cryogenic and Demagnetizing Process works in tandem with other design-in features to create the most optimized power and signal transfer possible.  Furutech’s total awareness and devotion to detail results in a greater sense of power, dynamics, and resolution, with cleaner, blacker backgrounds and a larger, more stable soundstage, vivid tonal colors and deeper extension at both ends of the frequency range.
