Why speaker cabling matters so much with ribbon drivers

A Clarisys ribbon has an impedance of roughly 0.1 to 0.15 ohms — a fraction of an ohm. That is what makes it a true ribbon, and it is also why the speaker cable you use matters far more here than it does with a conventional 4- or 8-ohm speaker.

The problem of scale

With an 8-ohm speaker, a few milliohms of cable resistance is a rounding error — well under a tenth of a percent of the load. With a 0.1-ohm ribbon, those same few milliohms are several percent of the load. The cable is no longer a negligible connector; it is a significant part of the circuit, and anything it adds — resistance, inductance, a non-uniform contact at a binding post — is heard directly.

The transformer multiplies it

The ribbon is driven through a step-up transformer, and that transformer reflects the series impedance of everything ahead of it — cable, contacts, junctions — back into the ribbon's circuit. A small impedance added at the connection point between the cable and the speaker is multiplied by the transformer's turns ratio before it reaches the ribbon. What would be inaudible on a conventional speaker becomes a measurable, audible change on a ribbon.

It shifts the crossover

That added series impedance does not just attenuate the signal — it changes the values the crossover sees. The crossover's capacitors and inductors are computed against a specific load impedance. When the effective load changes because the cable and its contacts have added series impedance, the actual crossover point moves, the Q of the filter changes, and the balance between the ribbon sections shifts. The speaker is no longer operating at the values it was designed and measured against.

Why Clarisys Audio cables

This is why we recommend Clarisys Audio cables. They are designed with the same low-impedance, low-junction philosophy as the internal wiring — pure-metal conductors, consistent geometry, and terminations that do not introduce a variable into the circuit. With a load this low and a transformer that multiplies every variable, the cable is not an accessory; it is the last component in the signal path, and it has to behave like one.
