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
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.
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.
ADDITIONAL REQUIREMENTS FOR SURROUND SOUND
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.
