Peak Speaker Cables 






Quiescent’s Peak low noise speaker cables are capable of bringing astonishing clarity to any system, dramatically improving the audio experience.


Building on the knowledge gained over the last 25 years, our engineers re-evaluated the effects of electromagnetic interference on radio frequency propagation along cables. They also researched the mechanical vibration of conductors and the impact of lower-frequency agitation of output components in power amplifiers. The Peak Speaker Connection System is the resulting combination of products that mitigate against these damaging sources of noise.

When designing the Peak, our engineers evaluated lower-cost materials to ensure that radio frequency propagation through and mechanical vibration of conductors could be minimised. The result is the Peak low-noise speaker cables that have an astonishing performance for the price.
Whilst many manufacturers focus on the conductivity of signal, the goal for Quiescent engineers was to determine 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 technology that would not interfere with or damage the musical signal in any way but to ensure that any unwanted noise could be eradicated for superior performance.
Peak speaker cables will surprise even the enthusiast, with high-performance cables costing twice the price. Cable construction is identical to Apex speaker cable, but we use lower-cost conductors and connectors to ensure we can bring Quiescent performance for those with more modest budget goals.
