USEFUL NUMBERS
There are lots of measurements which can be carried out on loudspeakers, not to mention
a confusing number of incompatible methods by which these measurements can be
executed. But, in terms of saying something meaningful about how a given loudspeaker
will actually sound, only a handful of data specifications are of any real use. You should
pay special attention to specifications for sensitivity and impedance.
Sensitivity is an indication of the sound pressure level which the speaker can generate for
a given input power. High sensitivity means that you can reproduce dynamic passages
without spending a fortune on a high-powered amplifier.
The linear impedance of DALI loudspeakers offers ideal stress-free operating conditions
for amplifiers.
