The Siren Speaker Cable
The Siren Speaker Cable
The Siren Speaker Cable applies the design priorities of Evidence Audio to a cable that can handle the demands of an amplified signal without adding distortion through strand interaction.
While line-level cables can avoid the smearing caused by skin effect using a 20-awg conductor, a single 20-awg conductor does not offer enough cross-sectional area to keep the wattage of your signal from turning into heat. The solution is to use three audio optimized conductors for positive, and three for negative in a helical array to lower resistance and provide ample dampening between an amplifier and the speaker drivers.
The helical array provides a twisted-pair geometry balancing inductance and capacitance for a very dynamic sound, and the open-core design further spaces the conductors from each other to greatly reduce any magnetic interaction between them.
Our proprietary high-purity IGL copper conductors exceed IACS conductivity standards for annealed copper, producing distortion-free midrange and high frequencies.
Solid-core conductors eliminate the negative effects of strand interaction on the audio signal.
Six individually insulated 20 awg conductors keep skin-effect distortions outside of the audible spectrum.
Our open-core design provides twisted-pair geometry with spacing between poles for reduced magnetic interaction, delivering dynamic and dimensional sound.
Polypropylene insulation holds conductors rigid to minimize electro-magnetic modulation of the conductors.
The Siren comes standard with Neutrik™ phone plugs and Speakon connectors. The connectors use a high-copper-content brass, which has the perfect balance of conductivity and strength, along with a unique chuck system to keep the cable mechanically attached to the cable for life.
The brass contact points have a nickel plating, which does a good job of protecting against corrosion.
While gold plating has a higher perceived value than nickel plating, gold offers no conductive advantage and is not worth the additional cost.
The fact that gold plating is done on top of an existing nickel plate to look good only makes the connector sound worse by forcing the signal to transfer through the additional layers and impurities that collect between them.
The connectors are soldered to the Siren using TRT Wonder Solder Signature.
All cables are directional. Drawn copper elicits a grain structure with a chevron shape, clearly visible under a microscope. Each run of Evidence Audio cable is listened to and tested for directionality.
Once directionality is established, a red boot is used on the output side of the cable. Between a guitar and amplifier, connect the red boot to the amplifier.
Cables sound best after carrying a signal for approximately 40 hours. This is due to the dielectric forming. As the conductor’s insulation material stores and releases an electric signal, its molecular characteristics stabilize with regard to how they store and release the energy applied by the conductor. Expect any cable to sound its best only after passing a signal for 40 hours. Note that approximately 80% of the change occurs during the first 10 hours a signal is presented to the dielectric. Don’t expect too much after that.
