The Primer Core Speaker Cable is the entry point to Entreq’s new cable architecture, succeeding the Primer Pro Speaker Cable. It is designed around the same principle as Delphius, that a signal is shaped as much by the electromagnetic environment around the cable as by the conductor itself, and brings that approach to a wider range of systems.

At its core is the Energy Reference System (ERS) – a separately shielded reference wire that works in concert with the Corepoint Signal units supplied with every cable. Where a conventional drain wire carries induced noise away, ERS interacts with the electromagnetic field around the cable, with the Corepoint providing the stable reference point that allows it to do so. Each channel is supplied with its own Corepoint unit, ensuring left and right operate with matched coherence across the length of the cable run.

The Primer Core Speaker Cable is constructed entirely by hand at the Entreq facility in Sweden. It uses copper conductors, a copper ERS wire and hook, cotton dielectric, and connectors customised to our exact specifications. Each Corepoint Signal unit connects to the ERS wire via spade connector.

Entreq Primer Core Speaker cable is supplied with two Corepoint Signal units, one per channel. The cable is available with either spade or banana plug terminations, both featuring custom connectors built to Entreq’s specification. Standard length is 2.2m per channel, custom lengths available on request; please contact us for specifics relating to your system and speakers.

Every Corepoint unit can be taken further with the addition of an Entreq Max Post. The Max range — Max T, Max S, Max Ti, Max Pa, Max Pl and the range-topping Max Supreme – allows the performance of the cable to be extended further, incrementally, as your system and needs change. With two Corepoint units in a Primer Core Speaker Cable, the opportunity to refine performance is doubled. Your investment in Primer Core is not a fixed decision; it is the start of an architecture that grows with your system.

Primer Core is at its best as part of a properly prepared system. Entreq grounding, Magneus at the entry points, and Protectus, Vibbeaters and MaxMix T2 shaping the field around your components all make the next step more effective. Used together, as a coherent system, Entreq products let your components deliver everything they are capable of.

Entreq Technologies Used:

Tungsten Inside: The Entreq range of products bearing the Tungsten Inside mark contain a unique mineral mix that features Tungsten granules. Entreq’s own research has found this specific material to offer even greater performance when used in their grounding applications.

ERS: ERS stands for Energy Reference System. Entreq cables that feature ERS take a fundamentally new approach to signal coherence by using a separately shielded reference wire that interacts directly with the electromagnetic field around the cable, rather than simply draining noise away. The ERS wire should be connected to an accompanying Corepoint unit to provide the stable reference point that allows it to work.

Infinity: All Entreq cables feature the unique Infinity treatment which places the conductors under high-pressure. Research undertaken by Entreq has found this to be a crucial part of ensuring optimal performance.
