The Custom Made DCF124BW 12AWG Bi-Wire speaker cables utilize Furez Advanced Series Cable Line. This Furez 12AWG 4 conductor cable has multiple gauge stranding within a rope lay design of high strand count 99.997% OFHC C10100 Copper with quality foamed polyethylene insulation (FPE). The design yields a clean balanced sound. The Douglas Connection Custom Made Cables use advanced design techniques with high quality materials, which creates a wonderfully detailed sound stage, while controlling inductance, capacitance and magnetic field effects. These cables are great for your Stereo Audio, or Home Theater system.

The DCF124BW speaker cables are constructed of four 12 AWG conductors. Each conductor is made from 227 strands of wire, which make these cables very flexible. Each of the conductors is formed from seven 99.997% OFHC C10100 Copper Bundles. This cable is laid out in a Star Quad configuration, which is a superior method to attenuate EMI (electromagnetic interference). The finishing touch is your choice of a Black, or a Black and Gray braided sleeve, which protects the cables and is appealing.
How they are made:
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. Even some of the best solder is made from approximately 61% tin, 35% lead, 3% silver, and 1% copper eutectic. As you can see mostly tin and lead is what these solders contain. The IACS (International Annealed Copper Standard) chart below shows the conductivity of various metals relative to copper. Look at Tin and Lead. Tin is only 15% as conductive as copper, and Lead is a lowly 7% as conductive. Using tin and lead between the highly conductive speaker wire, and the connector is like putting a flow restrictor on your garden hose that only allows between 7% and 15% of the normal flow. That’s why we attach the connectors using crimp or setscrews when we construct your Cables. This allows for the best signal transfer without restricting the flow of music from your amplifier to your speakers.
