High grade OFC (Oxygen free copper)
Copper is an excellent electrical conductor; however, oxygen im-
purities within the crystalline structure can adversely affect that
conductivity. By refi ning the copper to a much higher grade of
purity, electrical conductivity can be improved and hence signal
quality.
Ferrofl uid cooling
Treble voice-coils are fi ne wires and tend to get very hot
when used for a long time, or at high volumes. This can cause
distortion and compression if the excess heat cannot
be removed. Ferrofl uids are used in treble drive units to sink
heat between the voice-coil and the magnet assembly. They
also passively damp the movement of the cone. They reside in
what would normally be the air gap around the voice-coil, held in
place by the speaker’s magnet.
Neodymium
Neodymium magnets (NdFeB) are one of a class known as
‘rare earth’ magnets. They are also sometimes known as ‘super
magnets’ because of their unbelievable strength and small size.
They are ideally suited to audiophile loudspeaker applications
because of their strength, low weight, small size and their thermal
stability.
Die-cast Chassis
Die-cast chassis are a huge improvement over plastic or even
pressed steel units. Because of the manufacturing technique
used, they can have a more complex three dimensional shape
hence are much stronger. Because of their higher strength, they
can be manufactured with an open frame design. This allows
air moving backward from the cone to flow and be absorbed
within the cabinet rather than being reflected back through
the cone. There is an obvious improvement to mid-range clarity
and timing.
