generated by current within the voice-coil and this needs to be
controlled to avoid compression and even damage to the unit.
Mission’s new heatsink coupled treble units conduct heat away
from the treble unit very effectively, keeping control and maintain-
ing a consistently high standard of dynamic performance.
Ferrofluid cooling
Treble voice-coils are fine 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. Ferrofluids 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 be-
cause 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.
