Kubala-Sosna Persuasion Speaker Cables

The speaker cable is the link with the most current passing through it, and the link between the amplifier's voltage and the driver's motion. It is where mistakes are most audible — and where good engineering most rewards a serious system. Kubala-Sosna's speaker cables are sold in pair pricing because they are built as pairs, terminated with the listener's preferred combination of spade, banana, or flex-pin connector. Single-wire (SC1) covers most installations; Internal Bi-Wire (SC2, available at every tier except Imagination) gives the high-frequency and low-frequency conductors their own paths inside one jacket — preserving the bi-wire benefit without doubling the visible cable count behind the speakers.

Persuasion is the mid-OptimiZ sweet spot. It does not introduce new product types; it executes the existing complement at a higher level. The build is more demanding, the materials more refined. This is where the line stops feeling like a starting point and starts feeling like a destination — listeners often stay here for years. The right customer is the listener with a fully sorted system who knows the cables are doing real work and wants the OptimiZ architecture without crossing into the Fascination price step.

Persuasion as the speaker cable is the cable to put on a system whose component stack is genuinely settled, where the rest of the loom is moving up to OptimiZ at the same time, and where the listener intends to live with the result. Single-wire SC1 is the default and the right answer for most reference two-ways and full-range floorstanders; the SC2 internal bi-wire option is engineered for the speaker designer who specified separate high-frequency and low-frequency binding posts and the listener who wants that benefit without the visual clutter of doubled external cables. Termination — spade, banana, or flex-pin — is matched to the binding posts on amplifier and speaker at build. This is where the line stops feeling entry-tier and starts being the cable a listener keeps.
