All this technical jargon may sound confusing, but it basically means that you have a number
of options, each of which produces a different amount of bass. For example, if you like a lot of
heavy bass, consider putting the Elura TRI-SUBR8/TRI-SUBR10 into a corner. If you like
smoother, less-obvious bass, move the subwoofer out into the room. The main thing to
remember is that there is no “right” or “wrong” place to put the Elura TRI-SUBR8/TRI-SUBR10.
It all depends on how much bass you want.
Another reason to experiment – because low bass waves are very large (up to 40 feet or more
across!), they tend to cancel and reinforce each other, causing places in the room where there
is lots of bass and others where there isn’t very much at all. If you walk around your listening
room while playing music, you’ll probably discover these sorts of areas where bass is either
exaggerated or reduced. Needless to say, if your main listening area ends up in a “dead” space,
you will need to move the Elura TRI-SUBR8/TRI-SUBR10 so that bass is more normal.
Incidentally, moving the Elura TRI-SUBR8/TRI-SUBR10 around won’t affect the stereo imaging
of your main stereo system, so feel free to try various subwoofer positions.
Connecting to a wall plug
The Elura TRI-SUBR8/TRI-SUBR10 draws a moderately high amount of current. We do not rec-
ommend plugging it into a “convenience” outlet (switched or unswitched) that is often found on
the back of receivers and other stereo components.
Instead, connect the subwoofer ONLY to its own AC outlet. See items 9 and 10 in the Safety
Instructions on Page 2 of this manual.
D. CONNECTIONS
Three basic connection options
1. Connection to electronics with subwoofer or LFE output.
If you own a surround sound
receiver or integrated amplifier with a subwoofer or LFE output, use Method A as shown
in Fig. 3.
2. Connection to stereo preamp and amplifier.
If you have separate preamp and amplifier,
use Method B as shown in Fig. 4.
3. Connection to flat-panel TV.
If you have a flat panel TV with stereo analog audio outputs,
use Method C as shown in Fig. 5.

C. PLACEMENT
Where to position your
Elura TRI-SUBR8/TRI-SUBR10
The Elura TRI-SUBR8/TRI-SUBR10 operates at low
bass frequencies which are essentially omni-direc-
tional. That means you can place the Elura TRI-
SUBR8/ TRI-SUBR10 almost anywhere in a room
without compromising the effectiveness of your
main stereo speakers.
Four factors need to be considered:
1)
distance from your main speakers;
2)
distance from a wall outlet;
3)
distance from your receiver, amplifier,
or flat panel TV; and
4)
proximity to walls and corners.
5)
CAUTION: The Elura TRI-SUBR8/TRI-SUBR10
are not magnetically-shielded. If used with an
older CRT monitor or TV, keep it at least 2 feet
from the monitor.
1. Distance from your main speakers.
The best
placement for your subwoofer is on the same wall
as the main speakers, especially if you are match-
ing up with small bookshelf speakers. With tower
speakers, side wall or rear placement is also
acceptable.
2. Wall outlet.
Since the Elura subwoofer requires
AC power, it must be placed where it will reach a
wall outlet. We don’t recommend extending that
range with an extension cord.
3. Connections to your receiver, amplifier, pre-
amplifier or flat panel TV.
You will need to con-
nect the subwoofer to your receiver subwoofer out-
put or LFE output, flat panel TV, or preamp line
level outputs (see next page). You can basically
place the Elura TRI-SUBR8/TRI-SUBR10 anywhere
in a normal-sized room.
4. Proximity to walls and corners.
Physical
placement of the subwoofer will have a definite
impact on the frequency response and the per-
ceived amount of Elura TRI-SUBR8/TRI-SUBR10
bass output. Because low frequencies have long
wavelengths, they are influenced by proximity to a
boundary such as a wall or floor.
See Fig. 2. When you place the Elura TRI-SUBR8/
TRI-SUBR10 well away from a wall, it will produce
bass at a certain level. Move the subwoofer close
to the wall, it will produce more output (about 3dB
more). Putting the subwoofer in a corner will
increase output another 3dB (6dB more than when
placed away from walls and corners).
