8.0 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, it is not possible to define an unequivocal level for use in
comparing different speakers.
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 (clipping) amplifier contains
much more high-frequency information than an undistorted signal, and therefore puts a heavy
strain on the tweeter. Consequently, speakers are often damaged by small amplifiers, having to
work too hard - and very rarely by large amplifiers, which are practically running idle.
It is worth noting that turning tone controls above the neutral setting significantly burdens both
speakers and amplifier. On a good sound system tone controls should only be used to compensate
for poor recordings and not to permanently compensate for weaknesses elsewhere in the system.
Therefore 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 for the sound to remain clear and undistorted will minimize the
strain on both speakers and amplifier.
All DALI loudspeakers are designed with linear impedance for an optimal amplifier load. The result
is a significantly more open and detailed sonic image.
9.0 DALI IKON SUB
9.1 POSITIONING DALI IKON SUB
Both the amount and quality of the deep bass depend on the size and shape of the room, the
position of the subwoofer(s) and the main speakers. If positioned near a side or back wall, the
bass will be accentuated. A corner position will accentuate it even more, and we recommend
this position, as it increases the maximum bass output while simultaneously reducing the risk of
overloading your subwoofer.
DALI IKON SUB features a front-firing woofer and located at the rear side of the subwoofer is a
heat sink, which can become hot when the subwoofer is powered. Make sure the heat sink is not
blocked or covered. Ensure a minimum distance of 5 cm/2” between the heat sink and the nearest
obstacle to secure free airflow around the heat sink.
9.2 CONNECTION of DALI IKON SUB
DALI IKON SUB has a built-in power amplifier with an active crossover. The inputs of the subwoofer
amplifier should be connected to your stereo or surround sound (pre-) amplifier/receiver using a
RCA cable (sold separately). When changing connections, always disconnect the mains voltage
from the subwoofer to prevent damage.
The subwoofer can be connected to your stereo or surround sound amplifier/receiver in two ways:
1) LINE input: the signal from the amplifier is low pass filtered inside the subwoofer using
one or both of the LINE INPUTS. This way of connecting the subwoofer is typically used for
connecting to a stereo amplifier/receiver.
2) LFE input: the signal from the amplifier is filtered inside the amplifier when using the LFE
input connector. This way of connecting the subwoofer is typically used for surround sound
(A/V receiver) setups.
NOTE: When the subwoofer is connected to the music/home cinema system, do not power up the
subwoofer until all other components are “on”.
