All Series 4 audio cables are meticulously assembled by hand in Orlando, Florida. Series 4 Star-Quad Speaker cables begin with ultra-pure highly conductive oxygen-free copper (HC-OFC) developed specifically for audio applications. Two 12AWG speaker conductors are the result of combining a 16AWG and 14AWG conductors opposite each other in a 4 conductor Star-Quad speaker arrangement. In the Star-Quad design Magnetic distortion is canceled by twisting strands clockwise and then wrapping the bundles counter-clockwise around one insulated large solid conductor. Tributaries Series 4 Star-Quad design results in a high performance speaker cable that looks as good as it sounds.
Star-Quad Geometry
Tributaries Series 4, 6 and 8 speaker cables all include a Star-Quad design. Star-Quad speaker cables are designed with four conductors, all wound together, in a “positive, negative, positive,negative” configuration. The cable is produced such that all 4 wires are evenly twisted together keeping each conductor the same distance from the center and ensuring each positive conductor is next to each negative conductor. The net result is the cancellation of opposing electromagnetic fields generated by each conductor pair. This design improves the system’s performance by preventing EMI noise from entering and distorting the signals in nearby low level audio, video or digital cables. Another benefit of the Star Quad design is the reduction of the cable’s inductance,again, improving the cables electrical performance and reducing the distortion it produces.
Special attention to cable geometry is given to the design of speaker cables. Speaker cables carry high current signals that are susceptible to magnetic fields. As a signal travels along a wire it creates a magnetic field that increases with signal voltage. This self-inductance impedes the signal by virtue of its inductive reactance. Star-Quad design cancels magnetic fields and improves the sound quality of your system.
Resistance
Resistance is another consideration when choosing a speaker cable. In simple terms: the larger the diameter of the cable or conductor;the lower the resistance. Cable resistance is expressed in ohms per unit. For instance, 500 feet of 16-gauge wire has a resistance of about 4 ohms. With speaker cables this becomes an issue. Because speakers exhibit input impedances in the range of 2 to 8 ohms, the resistance of the cable can add significantly to the overall load. For example, if a 4-ohm speaker is connected to an amplifier with a cable that exhibits a 4-ohm resistance, the cable will dissipate half of the amp’s power before it even gets to the speaker! Tributaries offers a full line of speaker wire with gauges from from 11 AWG to 16 AWG for your consideration. Below is a handy guide for choosing the correct size speaker wire for your unique installation.
For speakers with only a single pair of rear panel terminals, Tributaries combine the four conductors of the Star-Quad cable into two at each end of the cable. In this set up, when used as a full range cable, the Star Quad Design (Negative + Negative / Positive + Positive) will reduce distortion over using a standard twisted pair speaker cable. Plus, when doubling the conductors, the amount of metal is doubled as well.The larger size conductor will lower the cable’s resistance and provide higher current capability resulting in an increase in low frequency performance. Lowering the inductance and resistance means it’s easier for the amp to drive the signal down the cable. Sonically, the sound is smooth and fluent as well as more dynamic, due to better definition. Tributaries Speaker cables are sold in each.
