Meridian Speaker Cable

The fundamental limitation of a two-conductor speaker cable is geometric. Two parallel conductors carrying equal and opposite currents produce a residual magnetic field that does not fully cancel at any point in the surrounding space. This field interacts with the ambient geomagnetic environment, modulating the cable’s effective impedance in a manner that varies with latitude, orientation, and — critically — the hemispheric bias of the conductor material itself. The Meridian Speaker Cable addresses this limitation through quad-conductor star geometry: four conductors arranged at 90-degree intervals around a central axis, with opposing pairs carrying the signal and return currents in a configuration that achieves first-order and second-order field cancellation simultaneously.

Each of the four conductors is drawn from 10 AWG Equatorial-Grade OFC sourced within 2.7 degrees of the geographic equator, achieving an Equatorial Purity Index of 99.9997%. The nitrogen-injected PE dielectric separating the conductors eliminates the charge memory that accumulates in conventional solid dielectrics over time — a phenomenon that manifests as a gradual dulling of transient detail over the first months of use in lesser cables. The Kevlar-reinforced jacket provides mechanical stability without adding the microphonic artifacts associated with rigid shielding materials, and ensures that the precise 90-degree conductor spacing is maintained even under moderate handling stress.

The Meridian is offered with a choice of banana or spade termination, both gold-plated and precision-machined to tolerances that ensure full contact area with your amplifier and speaker binding posts. Directional markers are printed at 10-centimeter intervals along the jacket. These are not decorative. The Equatorial Splice point at the geometric center of each conductor establishes a preferred signal direction that must be respected. Reversing the cable after break-in will require a complete restart of the conditioning process.

Break-in for the Meridian requires 200 to 400 hours of continuous signal. We recommend beginning with our proprietary Equatorial Break-In Signal, available as a complimentary download with purchase, which alternates between swept tones and shaped noise bursts calibrated to exercise the full conductor cross-section uniformly. Customers upgrading from the Tropic consistently report a widening of the soundstage that they describe as three-dimensional — a direct consequence of the star geometry’s superior field cancellation.
