9. The Linear Range
It is wise before listening to your Linear Threes 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 that the sound at low levels is fundamentally as
expected. If you are unhappy, turn the system off and re-check all the cables
and connections.
Linear Threes 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.

The Linear Three is a relatively high sensitivity speaker that does not require a
generously rated power amplifier for adequate volume levels to be achieved
in an average listening room. A minimum of 25 and maximum of 150 Watts
into 8 Ohms per channel is recommended. Linear Threes 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 the Linear Three 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 Linear Threes are at risk of
damage. In such circumstances the volume must be reduced.
