Speaker cables face a very different set of challenges than line‑level interconnects. Instead of carrying small signals into high‑impedance inputs, they must link a low‑impedance, high‑current power amplifier to a loudspeaker whose impedance and phase angle vary continuously across the audible band.

At this interface, several issues must be controlled simultaneously:

• High current and voltage swings across a wide frequency range, without adding significant series resistance or voltage drop.
• Frequency‑dependent reactance (inductance and capacitance) that can alter the amplifier’s stability, change damping factor, or introduce frequency‑dependent losses and group delay.
• Interaction between positive and negative conductors (pole coupling), which can increase effective capacitance, store and release energy, and blur transient response and imaging.

A true reference‑grade speaker cable must manage all of these while remaining as electrically “invisible” as possible to both amplifier and speaker.

The XerXes Reference Speaker Cable is built specifically to address the electrical stresses at the amplifier–speaker interface.

A carefully tuned, multilayer dielectric system surrounds each conductor to reduce inductive and capacitive coupling between the positive and negative poles. This minimizes stored energy, pole‑to‑pole interaction, and frequency‑dependent reactance, helping the amplifier maintain control over the speaker across the full audio band—especially at high current and voltage swings.

Low series resistance and controlled geometry keep group delay and phase shift extremely small, so transient response, damping, and tonal balance remain stable from low bass through the top end.

XerXes uses a four‑cable stereo configuration, providing separate, optimized paths for each channel and allowing integration of auxiliary components or configurations (such as dedicated runs, bi‑wire/bi‑amp schemes, or future system changes) without compromising core performance.

In practice, the result is explosive and controlled dynamics, stable imaging, natural presence and pace, and preserved low‑level detail.
