Introduction
Dear music lover
Welcome to your new Dynaudio
subwoofer.
We’ve been designing, engineering and
creating speakers at our Denmark
headquarters since 1977, and ever since
we started we’ve been pouring advanced
R&D technology into every model.
What comes out is audio reproduction at
the highest level, making listening to
even the most familiar recordings a new
listening experience altogether. Our aim:
to reproduce exactly what was
happening in the studio at the time of the
original recording.
In fact, we’re one of very few companies
who can realize such concepts. That’s
thanks to Dynaudio Labs, our in-house
development and production facility.
It’s so advanced, in fact, that we’ve been
given TS16949 certication.
Each loudspeaker is constructed and
rigorously tested by our master-
craftsmen to these incredibly demanding
standards.
If you want to get the best possible
performance from them (that’s why you
bought Dynaudio in the rst place, after
all), take a look at the information on the
following pages. By considering our tips
and suggestions, you’ll be recreating
what our engineers do in our testing
rooms: extracting every ounce of detail
and nuance in the music… and then
enjoying every second of it.
We wish you many years of enjoyment
with your new subwoofer.
