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 Bi-Amp 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.
