Fault Finding
Tannoy loudspeakers are designed and manufactured to be
reliable. When a fault occurs in a hi-fi system the effect is
always heard through the loudspeakers although they may
not be the source of the fault. It is important to trace the
cause of the problem as accurately as possible. A fault
heard on one source (only CD or tape for instance) is most
unlikely to be a loudspeaker problem. Loudspeakers do not
in themselves generate hum, hiss or rumble although high
quality, wide bandwidth loudspeakers may emphasise such
problems.
