Evidence audio - Speaker
Clean Power Delivery
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. Music is music whether amplified or not, and when you compare variables in material quality, stranding and geometry between an amplifier and a speaker, you hear the same things you hear between a microphone and a pre-amp. The Siren speaker cable goes between an amplifier and speaker and lets the music play in an open, dynamic way that breaths without congestion, irritating high frequencies, ormuted and damped low frequencies robbed of speed and articulation.

- 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.


Helical Design: More Power, Less Heat
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.

About the founder
Evidence Audio was founded by Tony Farinella, who focused on design methodologies in his research lab more than 25 years ago.
His goal was to create cables that would preserve the quality of sound as it passes through electronics. Every cable is designed to “disappear” without imparting its signature on the signal path.
His innovation and next-level thinking continues to deliver precisely engineered products for the best Musicians, Producers, Engineers, Guitar Techs, and Rig Builders Worldwide.
