Speaker wire and interconnecting cables are an important 
component in any audio system. With a system like Project 
Everest, they assume an increased level of importance.

Project Everest loudspeakers are internally wired using high-
quality oxygen-free copper wiring. The same care that was 
given to the selection of the loudspeakers’ internal system wiring 
should be afforded to the selection and application of the wires 
that will connect the Project Everest loudspeakers to your other 
system components.

Many manufacturers produce audiophile speaker wire worth 
considering for Project Everest loudspeakers. As with all electronics 
and associated components, however, every manufacturer 
offers products of varying quality to suit a range of budgets and 
applications. We advise that you use high-quality wire and to 
select the highest grade of wire available from the manufacturer.

Project Everest specialist dealers have the experience and 
knowledge to recommend suitable speaker wire to best 
complement your particular system. We recommend using an 
audiophile-quality speaker wire of not less than 16-gauge for 
connections of up to 15 feet (5 meters) as a minimum requirement.

For maximum signal purity, we advise that you place the 
amplifier(s)  as  close  as  possible  to  the  loudspeakers,  even  if 
this means that a longer distance will be needed between the 
amplifier(s) and preamplifier.

The  connections  between  the  left  and  right  amplifiers  and 
speakers should be the same length. If the distance between one 
speaker and its amplifier(s) is greater than the distance between 
the other speaker and its amplifier(s), use the longer length of wire 
for both connections.

For bi-wire connections, the same type of wires may be used for 
both low-frequency and high-frequency sections to reduce wire 
effects (resistance, inductance, etc.) and to avoid intermodulation 
of low and high frequencies in the wires. Specialized wires for 
low-frequency and high-frequency sections may yield excellent 
results. Whatever wires you select, be sure that the low-frequency 
wires are as short as possible, and that the left and right wires for 
each section are the same length.
