HOW TO FINE-TUNE

THE IMAGING

If you are experiencing issues with imaging, first
ensure your speakers are in phase with each other. If
this is the case and imaging is still an issue, moving the
speakers closer together or toeing them in slightly
(angling them towards the listening position) can aid
in this respect. 

The cone feet can be used to tilt the OMD-28s slightly
forward. In certain situations where a lack of image
focus was found, this set-up adjustment has proven to
be an effective measure to improve image focus.

HOW TO FINE-TUNE THE

SOUNDSTAGE DEPTH

The soundstage depth can be adjusted by changing
the distance from the speakers to the back and/or the
side walls. If your system is lacking soundstage depth,
try to move the speakers further away from the back
wall.  If your soundstage is lacking width, moving the
speakers further away from the side wall is a good
measure to increase the soundstage width. In the
opposite cases, when the soundstage is overly large in
either width or depth, try to move the speakers closer
to the respective wall.

HOW TO INCORPORATE

ACOUSTIC ROOM TREATMENTS

If the sound has poor focus and seems to be too
"splashy" or indistinct sounding, more damping may
be required in the listening area. Experiment by
adding an area rug between the listener and the front
speakers if there is a bare wood floor. Some damping
treatment to treat the ROOM, not the speaker
reflection points, can work well to reduce this
problem. A number of different options are available
on the market, damping pads for the corners of the
room at the ceiling, pads for the corners of the room,
etc. A room can be tested simply by clapping while
walking around the room. The sound of the clap
should die off smoothly, but not instantaneously. If the
clap results in a long standing echo, the room may
require some acoustic treatment.

NOTE:

DO NOT ATTEMPT TO ADD DAMPENING

MATERIALS TO THE FIRST REFLECTION POINTS OF THE
SPEAKERS! OMNIPOLAR SPEAKERS ARE DESIGNED
TO EMBRACE SUCH REFLECTIONS AND THEY ARE A
CRUCIAL PART IN THE PERFORMANCE OF THE
SPEAKERS.

ADDITIONAL REQUIREMENTS

FOR SURROUND SOUND

SET-UPS

When installing a surround sound system, all the
above holds true. Calibration of your speaker
distances, adjusting delays and balancing your levels
with an SPL meter is recommended to extract the
most out of your system.
