DALI EPICON

WHITEPAPER
INTRODUCTION

Over the years DALI has continuously been

pushing the limit for what can be achieved in
terms of performance and build quality. With the
introduction and steady evolution of technologies
such as the hybrid tweeter module and wood
fibre cones the important high-end segment
has been the inspiration for DALI’s relentless
research and development.

And at a certain point these efforts are converted

into real breakthroughs in new technology, making
it possible to achieve so much more than what was
previously within reach. The time has now come
for a new reference speaker from DALI – the DALI
EPICON series.

Built on knowledge from almost 30 years of

research, development, and manufacturing of
speakers, and on results from experimenting with
both new and known technology the EPICON series
shows just how far DALI has come in our search for
natural sound reproduction.

With a visual appearance that signals exclusivity

and simplicity these speakers are for the most
demanding of music and movie enthusiasts. And
with a performance which is clearly DALI - taken
one step further – we intend not only to meet these
demands. We will surpass them.

This whitepaper will take you behind the scenes,

revealing some of the science that goes into
creating the magic sound experience distributed by
this new series….

… the DALI EPICON …

Enjoy!

LINEAR DRIVE MAGNET SYSTEM

For years designing magnet systems

has been a DALI specialty.

For the EPICON series we decided to

challenge the highest market standards
and to take magnet system design
further than ever before in order to
reduce distortion generated from less
than perfect magnet systems.

New materials, new processes - and

hundreds of hours of engineering
were needed.

And we are proud of the result!

 Force Factor
While many people know about the
importance of the right BxL product
(force factor) to generate sufficient
power for adequate sound pressure
levels and (even more important) the
desired electrical Q of the woofer (the
BxL product influences the Qe in the
power of two), little attention is often
given to the potential improvements in
a distortion reducing design.

The attention to the many factors in

magnet system design is especially
important in midranges and woofers,
where excursion is long and current
is high.

Symmetry and Stroke

Having tuned the design to the
desired BxL value the first step is to
ensure a symmetrical BxL curve with
as long as possible a linear stroke.
This design requirement is taken
into consideration in most speakers
in the market, except for very
inexpensive designs.

But the quest does not finish here.

It is important to reduce - ideally to
eliminate - all non-linearities in the
conversion of the output from the
amplifier to the force that drives
the cone.
