All models feature printed circuit
boards with large copper tracks
to maximize signal transfer and
component layouts designed
to eliminate inference from any
residual stray magnetic fields. The
printed circuit boards are mounted
on vibration free mountings. Most
models have two printed circuit
boards to separate the bass inductors
from those coupling the midrange
and tweeter units.
The bass inductor has a large
magnetic field when operating
which would otherwise modulate
the other inductors. All inductors
feature perfect layer winding and
large gauges of wire are used to
keep insertion loss to a minimum.
Capacitors in crossover networks
pose special problems. The Opus²
range features high grade low-loss,
low-ecr, polypropylene or reversible
electrolytic capacitors specially
selected for their outstanding audio
properties. These capacitors are
marked with the ‘Wharfedale super
audio capacitor’ logo. The internal
cables used are specially made and
assembled in our factory: 4 multiple
strand oxygen-free copper wires are
plaited into a single cable for all
internal loudspeaker connections.
