Euphonia IWS 3 Phantom
Low frequency adjustment is also beneficial when the Euphonia IWS 3 Phantoms is used
in conjunction with a subwoofer. Typically, it is possible to achieve better integration
between the subwoofer and the Euphonia Phantoms by experimenting with the low
frequency level switch and the various settings of the subwoofer (phase, level, crossover
frequency).
Crossover to Better Sound
The heart of any loudspeaker is the crossover. The Euphonia Phantom crossover is made
with high quality components that are point-to-point hardwired and glued/strapped on a
stable vibration absorbing base plate. By hardwiring point-to-point, the connection between
crossover components is optimised and loss is reduced to an absolute minimum.
The inductors in the crossover are wound from pure copper. The inductors are carefully
positioned and angled, to minimise any interaction of the electrical fields.
The capacitors are high quality polypropylene foil capacitors and large-surface bipolar
capacitors. The capacitors have been carefully selected for excellent sonic performance in
collaboration with the inductors and the rest of the loudspeaker design.
A single power resistor is used in the crossover. Wire-wound and based in an aluminium
house, it is screw-mounted to the base plate to eliminate any risk of mechanical noise.
We custom design all our drivers to achieve precisely the desired electrical and acoustical
characteristics. When we design the crossover, we can concentrate on the actual time
alignment and frequency separation to each driver. There is no need to use the crossover
to correct or compensate for any unwanted behaviour from any of the drivers. The result is
a small and simple crossover with a minimum of filtering – ensuring pristine signal transfer
to the drivers.
Connectors
The gold-plated spring loaded connectors are developed especially for
Euphonia Phantom.
The loudspeaker cable is secured by spring-lock mechanisms that
ensure constant tension on the cable for a long-lasting, reliable electrical
connection. This was chosen, as the accessibility to the cavity wall is not
as “easy” as a floor standing. The connectors are bolted directly to the
rear enclosure of the loudspeaker.
When designing the binding post we paid special attention to the conductivity. The
connector leading the electrical signal to the crossover is made in one piece, contra to
traditional design.
This ensures that there is no more conducting parts than absolutely needed - ensuring
minimum electrical loss.
