7. Amplifiers
10. Warranty
It is wise before listening to your speakers to make one
final check of the cables and connections. If all appears
well begin listening at a relatively low level to confirm
that the system is operating as expected. Only increase
the volume if you are happy with the sound at low
levels. If you are unhappy, turn the system off and re-
check all the cables and connections.
Extreme Series speakers may take a little time to “run-
in”, and similarly the system will also perhaps take
some time to reach normal operating temperatures. It
is unwise therefore to make rapid judgements about
the performance of the speakers. Your ears too will take
some time to adjust to the new sound, so revisiting the
system set-up, speaker positioning especially, is best
left for a few days.
9. Specifications
Extreme Series speakers offer relatively high sensitivity and do not require
generously rated power amplifiers for adequate volume levels to be achieved in
typical listening environments. They also offer a relatively easy load to the amplifier
and do not make unusually heavy demands on its power delivery.
No overload protection systems are fitted to Extreme Series speakers so it is
possible to cause damage through over-driving. Such damage can occur whatever
the power rating of the amplifier and is not covered by any warranty. If ever the
sound at high volumes becomes distorted your speakers are at risk of damage. In
such circumstances the volume must be reduced.
