Lowther EX-4 Drivers!
Listing is for a pair of drivers.
The surrounds on both drivers need replacing (see pictures).
EX series of drive units will completely transform all existing Lowther
Loudspeaker Systems. Every Lowther Owner may now enjoy the greatly superior
sound reproduction qualities which only the 'EX' drivers are capable of.
in the 'EX' range incorporates an acoustic chamber precisely tuned for optimum
performance. Cone assemblies are pressure balanced between the acoustic chamber
at the rear and a phasing equalizer fitted to the front. No unwanted
oscillations of the speech coil occur. Only bass frequencies will pass through
the acoustic chamber, so avoiding bass/mid-range confusion, often a cause of
latest method of construction, the inner cone is now isolated from the outer.
This is not readily visible, but what is noticeable is that the rim of the
inner cone is terminated with a reverse roll. Where once sound frequencies
cancelled each other and information was lost, now all that information is
retrieved and can be enjoyed. Where once sound frequencies were reinforced by
the two cones working in unison at certain frequencies, now there is no
over-forward sound reproduced. The frequency range is so smooth, and so much
more detail from the recorded source is reproduced, that an entirely new level
of listening experience will be enjoyed.
'state of the art' rare earth magnet technology is employed to enable complete
control of the diaphragm throughout the entire audible range. This results in
maximum information being extracted from the recorded source whilst delivering
a very smooth response at all frequencies.
series Drive Units are the best full range drive units ever produced. They are
designed to fit into every Lowther cabinet design, both past and present,
without any modification being necessary. These revolutionary drive units are a
must for all Lowther owners. Everyone can now enjoy an entirely new experience
of listening pleasure.
