The surround speakers
●
The surround speakers should also be placed at the same height as the
front speakers, and the distance to the listener should also be the same as
for the front speaker. Please refer to Figure 2.
Placement of the subwoofer
●
Single or multiple front subwoofers should supplement bass extension
for the main speakers, thereby making them full range. Separate
subwoofers also make setting up a room much more flexible. Subwoofers
have slight but noticeable influence on imaging.
Even sharp, low-pass filters allow for some bleeding above 100Hz which
is directional. Therefore we recommend front firing woofers. For the same
reason we recommend rather two wide-spread front subwoofers instead of
one.
When using both Lipinski Sound L-301 monoblock amplifiers and at the
same time the L-300 subwoofer amplifier you achieve perfect time
alignment. In this case the front screen of the subwoofer should be only 2"
in front of the loudspeaker's front screen. Using other electronics causes a
time smear effect, and usually if you want to achieve perfect time
alignment, you may need to push the subwoofer several feet in front of the
main speakers.
Cables
●
Try to keep them as short as possible. By its electrical parameters, a
long conductor of excellent quality will have a bigger influence on the sound
than a short a good quality. A long cable with insufficient shielding may also
pick up noise, causing a constant hum.
Make sure that all connections are clean and not oxidized. All
connections should be mechanically stable. Power, signal and loudspeaker
cables should be separated from other cables. If there is a need that they
have to cross each other, be sure that they are crossing each other at a 90
degree angle. Never line them up in parallel.
Finally
●
Please remember that good sound is a matter of taste and preference,
so you have to experiment to obtain it.
