Mounting options
Your subwoofer has three mounting
possibilities. (You will need an assistant
to help lift and position the subwoofer.)
A. Free standing.
Two brackets are easily fitted to the
subwoofer with thumbscrews.
B. Vertically.
The subwoofer can be
fitted up against a wall,
with one foot bracket on
the floor. The subwoofer
must be held to the wall
using special fittings sup
-
plied, and it must have
one of the foot brackets
fitted to the lower edge.
Never leave the subwoofer
standing vertically without it
being secured to the wall.
C. Flat.
The subwoofer can be fitted with
four supplied feet, and placed on its
back. It can even fit under couches.
See page 18 for more details of the
different mounting options.
Finding a good location
Although low frequencies are non-di-
rectional, factors such as room reflec
-
tions, standing waves, resonance and ab-
sorption will strongly affect your subwoof-
er’s performance. Moving the subwoofer
from one location to another can have a
major effect on the bass response.
The Auto EQ mode will let you adjust
for the room effects, but you should find
the best location first.
Subwoofer installation
The following procedure will help you
find the best location for your subwoofer.
(This method may seem a bit odd, but it
is based on solid principles of acoustic
physics.)
1. Start by placing the subwoofer right
on the seat of your favorite couch
or easy chair, with the woofers fac-
ing upwards. Position it with care
so it is not likely to fall off. If this is
not practical, then move the couch
and place the subwoofer either face
up with four feet attached (mount-
ing option C), or horizontally with
two brackets attached (option A).
2. Connect the SubRosa amplifier and
the subwoofer with speaker wire,
and connect a power cord to the
amplifier.
. If you are using the subwoofer as
part of a Home Theater system,
you can either run a calibration
test (noise) signal through the
subwoofer, or simply plug the ana-
log outputs of a CD player directly
into the sub amp’s line-level inputs.
Turn down the sub amp's volume
level before turning on the CD, then
play some of your favorite music
samples with heavy bass.
3. Walk around the room, listening,
and stand in all the positions where
you might be able to place the
subwoofer. Try crouching down,
and try the corners. Find the most
practical place where the subwoof-
er's bass output sounds best.
4. Shut things down and install the
subwoofer in this position.
Magnetic Fields
We recommend that you place
your subwoofer further than two
feet away from your TV, VCR, tape
deck or computer, so the speaker’s
magnet won’t distort the colors of your TV
picture or erase your video tapes, audio
tapes or computer discs.
