Technology

The Apex is the ultimate in high-end speaker cabling. It is built on the knowledge gained over the last 20 years minimising high-frequency noise-causing inter-modulation of the audio signal. In addition, our engineers re-evaluated the effects of electromagnetic interference on radio frequency propagation and mechanical vibration of conductors devising an improved solution to absorbing these damaging artefacts. The result is the Apex ultra-low noise speaker cables.

Whilst many manufacturers focus on signal conductivity, the Apex uses methods to control the propagation of damaging electrical and mechanical oscillation transmitted along the length of the cable. A key design consideration was to use filtering strategies that do not interfere or damage the musical signal in any way while ensuring that any unwanted noise is eradicated, providing superior performance. The Quiescent ultra-wideband, multi-phase filter is the culmination of our research, and it is so small that you wouldn’t even know it is there. The only indication of its presence is an improved audio experience overall.

Another vital characteristic of all our cables is that we use conductors that sit within a Teflon™ air tube, ensuring that capacitance is incredibly low. AS a consequence, the signal’s time domain as it is sent to the speaker undergoes no phase changes. Once the conductors are in their air dielectric, they are fed into our proprietary EMI absorbing sheath and finally into a braiding with very low acoustic transmission properties.

With all this attention to detail and manufacture, the Apex speaker cables have a low noise floor and a high transient current carrying capability, improving musicality, bass propulsion, and tonal accuracy to an extent that is impossible to miss.
