The long-throw ratio design of the chassis provides
headroom for extreme cone excursions. Even when
the cone is pushed to the maximum, it will not
reach physical limits of motion.
The motor system within the woofer is based on
a solid ferrite magnet. The magnetic saturation of
the centre pole prevents distortion through a stable
magnetic flux density in the voice coil gap. On top
of this, the drilled and chamfered ventilation in the
centre pole provides total ventilation behind the
dust cap.
We use a 1” voice coil providing the optimum
combination of low moving mass and long linear
motion. This offers a wide frequency band and
dynamic, unrestrained reproduction.
When it comes to mechanical losses, it is clear that
the vast majority of these are extremely non-linear,
thereby adding level-dependent distortion to the
driver’s reproduction. At DALI, we believe in designs
based on low mechanical loss.
It is well-known within the industry that it is quite
easy to control frequency response by adding lots
of mechanical damping in e.g. surround and cones.
But our approach remains: We do not want to use
non-linear mechanical effects to control, damp
or limit the movement of the parts that should
reproduce the music. The amplifier voltage and
current must be the factors that control motion.
DALI was one of the first manufacturers to insist
on controlling frequency response through carefully
balanced designs, even with low-loss rubber
surrounds that will reveal problems in many well-
known driver designs.
Listening to the IKON MK2 family shows that it is
worth the struggle, however. By letting the amplifier
take control, we strive for the music to dominate –
and not the character of the speaker.
Consequently, free and open performance is
achieved. Increased dynamics is an added benefit.
No matter if you play at subtle levels or crank up
the volume, the IKON MK2 products will ensure that
no details are left out.
