Speaker cable has a unique set of properties. What may be an ideal conductor for interconnects, may prove unsatisfactory for delivering a signal from the amplifier to the loudspeaker. High current capability, low impedance, and linear behavior throughout the audio spectrum are ideal traits. In keeping with the Cerious Technologies design philosophy of establishing the design process with an ideal to be achieved and allowing that ideal to dictate the materials and construction used, the development of the speaker cable took several unexpected turns before a final design was created.

Research based on the loudspeaker/amplifier interface revealed that the key elements were the proper loading of components found in passive crossovers used to divide the frequencies for the individual drivers. These crossovers employ a “ground central” philosophy. In simplistic terms, the “negative” terminal on the loudspeaker operates with different properties than the “positive” terminal. This meant that the “ground” lead of the speaker wire would be a different configuration from the positive. Listening tests confirmed this theory.

Key to the ground cable was pure brute force. In loudspeaker terms this would be equivalent to “the more mass the better”. Experiments even included 00(2.0) silver wire. Modeling revealed that an ideal was a mix of old and new technologies, meaning a composite that used a mix of conductive composites and wire. Termination and sealing processes were then developed to maximize longevity.

The positive lead offered a more complex mix of criteria. Here we could go full composite and draw on research conducted for interconnect development with regard to conductor geometry and damping. Each positive lead employs hundreds of thousands of strands of micro fiber saturated with proprietary Cerious liquid. This bundle is then encased in pure Teflon tubing compressing the bundle. This results in near ideal damping characteristics and stability.

The two conductor bundles are then surrounded by the same Cerious Technologies synthetic liquid ceramic jacket employed in our interconnect cables. A larger diameter jacket is used allowing greater volumes of synthetic ceramic damping material. This will aid in absorbing the higher amplitude fluctuations found in speaker level signals.

Standard termination is with gold over copper spade lugs. Other terminations are available on request.

So how does it Sound?

While the design and production of these remarkable cables proved to be challenging, perhaps an even more difficult task is describing their “sound”. Once you hear a complete system with no metal-based wire present, you can hear wire. There is a freedom from grain, noise, and an alluring sense of musicality once you are free of metal. The noise floor is scaringly quiet. This displays itself in new levels of ambient information and vision into the acoustic soundspace. It's as if the Liquid Ceramic Speaker Wire isn't there.

One caveat. Cerious Technologies Liquid Ceramic Interconnects and Cables are very cumulative. Each piece of cable you replace will reap greater sonic returns as you move towards the no wire experience. The last piece you replace will likely remain the last piece you replace. At least for the next 20 years....
