Owners guide for DLS loudspeakers

Introduction

Please read this manual fully before
unpacking and installing the product. It will
help you to optimise your speakers
performance.

Unpacking and maintenance

Your speaker should be treated with the
same care you would treat a piece of
furniture. Use a piece of soft cloth and a
small quantity of warm soapy water to
clean the loudspeakers. Avoid touching
the cone of the bass unit or treble dome
since this may leave a fingermark or
damage the dome and spoil its
performance. After unpacking, we suggest
you retain all packing material for future
transports.

Running-in period

The performance of the speaker will
change subtly during the listening period.
Please allow your new speakers to play
about 50 hours of music at normal list­ening level before doing any critical list­ening.

Room positioning

The performance of a loudspeaker system
in a room varies with placement. Ideal
positioning of the speakers are 3-4 m
apart and preferably at least 0.5-1m away
from side and rear walls se fig. 1. Avoid
distances from walls that correspond to 1/
2, 1/4, 1/6 etc., of the room dimensions.
Seek instead odd fractions; 1/3, 1/5, 1/7
etc.to minimize effects of room related
resonances.
You will perceive the most accurate sound
picture if you listen from a position halfway
between the loudspeakers, and three to
four metres away. Avoid corner placement
as it leads to colouration and an over­emphasise of the lower frequencies.
Image stability and stereo perception is
increased if the two speakers are turned
slightly towards the listening position. Try
this out and listen for best stereo image
and centre focus. Objects in the direct
sound path can disturbe the coherence of
the sound picture. Try out different
positions before deciding on a final arr­angement.

Stability

All floorstanding models are delivered with
spikes providing improved acoustical
isolation and height adjustment. To obtain
proper mechanical coupling to the floor,
adjust until all spikes have equal contact.
Floor standing models are also equipped
with an internal sub-cavity, intended to be
filled with sand with a grain size of more
than 1mm. For environmental reasons we
do not recommend lead shot. Carefully
remove the sand plugg under the terminal
on the rear of the speaker, and fill up. The
increased mass will enhance contact with
the floor, further reduce resonances and
increase stability and focus of the
soundstage.
