POWER HANDLING
The efficiencies of Hi-Fi loudspeakers are well under 1%
(typically under 0.2%). This means that over 99
percentage of all power produced by the amplifier will be
converted into heat in the loudspeaker. Excessive heat
may give rise to the over heating of crossover
components and driver voice coils. When the power
handling capability of the speaker is exceeded it is likely
that the tweeter voice coil wound of a very thin wire will
be burnt first.
A loudspeaker can be damaged also by low powered
amplifier when over-driven (loaded). In this case the
amplifier will clip and cause high ordered distortion
components (high notes) which easily burn the treble
driver voice coil.
Gradient Evidence loudspeakers can handle high
powered peaks of short duration. Music of varying
dynamics can be listened to at a high volume level. If the
music sounds continuously loud and it is played for a long
time, it is probable that the heat builds up faster than the
drivers can dissipate it. As a result the speaker drivers can
be damaged.
