Power and acoustic pressure

How loud a speaker is able to play and still sound good is completely
dependent on the signal it has to reproduce. So, in practice, you cannot
define an unequivocal level for use in comparing different speakers.
Obviously, lots of pure, undistorted output
from a large amplifier is better than a distorted
signal from a small amplifier stretched beyond
its capacity. The signal from a distorting (clip-
ping) amplifier contains much more high-
frequency information than an undistorted
signal, and therefore puts a heavy strain on
the tweeter. Consequently, speakers are most
often damaged by small amplifiers having to
work too hard - and very rarely by large ampli-
fiers, which are practically running idle.
It is worth noting that when the tone controls
are turned above the neutral setting this signi-
ficantly burdens both speakers and amplifier.
On a good sound system tone controls should
only be used to compensate for poor recor-
dings and not to permanently compensate for
weaknesses elsewhere in the system. So, DALI
recommends that the tone controls generally
be set to the neutral position, and you achieve
your desired sound image through correct
positioning of the speakers.
Ensuring that you keep the volume low enough so the sound remains clear
and undistorted will minimise the strain on both speakers and amplifier.
DALI recommends that the tone controls are set to neutral position.
