Location
The suggestions below will typi-
cally result in outstanding performance.
However, although low frequencies are
non-directional, factors such as room
reflections, standing waves, resonance
and absorption will strongly affect your
subwoofer’s performance.
Since your SubRosa subwoofer is de-
signed to be professionally installed into
your wall, engineering services from your
Authorized Sunfire Dealer and/or outside
acoustical resources should be consid-
ered to ensure optimum performance.
The SubRosa amplifier’s Auto EQ
feature will tailor the sound to the room
for optimum performance in the location
you choose.
Keep the subwoofer at least
two or three feet away from any
TV screen, computer, VCR or
magnetic tapes and discs. This will
reduce the chance of the magnetic fields
upsetting the TV screen or erasing your
magnetic media.
Corner installation
Installing the subwoofer
on the front wall, towards the
corner will reinforce the low
frequencies.
This is best suited for:
•
Rooms larger than 200
square feet where a
single subwoofer will be
used,
•
For dedicated home
theaters
•
For listeners who enjoy
“heavy” bass.
Corner location
User's Manual

Download from Www.Somanuals.com. All Manuals Search And Download.
Center location
Installing the subwoofer
closer to the center of the front
wall will still provide adequate
bass, but will tend to be less
“heavy” and somewhat tighter.
This is ideally suited for:
•
For rooms smaller
than 200 square feet
•
Dedicated music
listening rooms.
Central location
Using Two Subwoofers
If you wish to use two subwoofers, the sound output will double. Locating the
subwoofers on the front wall, with one towards each corner will provide more flexibility in
crossover points, without causing localization that can happen with subwoofers located
on side and rear walls. Sunfire preamplifiers and receivers feature multiple subwoofer
outputs for these applications. If your preamplifier has a single sub/LFE output, use a Y
cable to split it into two outputs.

Framing
Vertical mounting
1. It is recommended that you add a
horizontal brace below the cabinet
to raise it above the height of the
finished floor and baseboard mold-
ing. This will prevent accidental nail
punctures in the cabinet.
Due to residential construction meth-
ods, vertical mounting of the cabinet is
recommended. The subwoofer cabinet
will fit between 2 x 4 inch studs on 16
inch centers.
Horizontal mounting is also possible,
but needs additional framing steps. See
page 10 for horizontal mounting details.
2. Add a horizontal brace above the
subwoofer cabinet, leaving enough
room to make your speaker wire
connections to the push-terminals.
Notes:
•
Use the illustrations as a guide,
but follow all local building codes
regarding the actual framing meth-
ods.
ꢀ. Add further horizontal braces at
either side of the cabinet, but
make sure that they are at different
heights to randomize wall reso-
nances.
•
The insulation stuffed inside the
cabinet is required for proper oper-
ation. Do not remove the insulation
during the cabinet installation.
4. Attach self-adhesive foam strips to
the cabinet wherever there will be
contact with the studs or sheetrock.
Use longer strips for the sides, and
shorter strips for the front face and
the shorter side resting against the
lower horizontal brace.

Cabinet Installation
1. With the help of an assistant to
lift the cabinet, check the fit of the
cabinet into the framing. Use wood
shims if there is any gap between
the cabinet sides and the vertical
studs.
4. Use a level to check that the cabi-
net is vertical.
5. Use six woodscrews (supplied) or
more on each side to secure the
cabinet in place. Do not screw into
any of the joints of the cabinet. The
cabinet walls are 3/4 inch thick, so
make sure the screws do not pass
all the way through. (The supplied
screws will not pass through, if

used with standard 2x4 studs.)
3. When you are happy with the fit of
the cabinet, apply wood glue, such
as Liquid Nails™ along the cabinet
sides. Fit the cabinet into the fram-
ing until its front face is flush with
the front face of the framing.

all local codes for electrical wiring
installation. Use class 2 wiring,
and 12 gauge is recommended, 16
gauge is the minimum.
2. Follow common low voltage
practices like avoiding high voltage
electrical wiring, or crossing them
perpendicularly. This will reduce the
chance of picking up hum or other
interference.
6. Use caulk to seal the nearest cable
holes to the cabinet. This will pre-
vent air movement and secure the
cables in place. Due to the nature
of subwoofers, it is a good idea to
secure the wiring from vibration as
much as possible. Do not have the
weight of the cables hanging on the
terminals.
ꢀ. Make the speaker wire connec-
tions to the subwoofer terminal cup,
observing the correct polarity. The
terminals are spring-loaded.
4. Secure the wire to the studs with
electrical staples to prevent rattles
and movement in operation.

Final Rough-in
1. Make sure the debris shield is fitted
into the cabinet opening using the
plastic push rivets supplied. This
will prevent dust and sheetrock
debris from entering the cabinet.

Sheetrock installation
1. Apply glue to the framing surround-
ing the cabinet. Also apply glue
to the front surface of the cabinet,
wherever it will be in contact with
the sheetrock.
ꢀ. Fit the sheetrock in place with
sheetrock screws spaced 4 inches
apart.
4. Carefully cut away the sheetrock to
reveal the cabinet's aperture. Now
that you can see the location better,
add screws to secure the sheetrock
to the front face of the subwoofer
cabinet. Make sure that no screws
pass close to the speaker wires or
the terminal cup.

5. With the cardboard debris shield in
place, the walls can be painted and

in place until you are ready to
install the woofer baffle assembly.
It can be removed by cutting it and
carefully pulling out the rivets hold-
ing it in place.

Horizontal mounting
In this position, the subwoofer's longest
side is horizontal. This may be required
for some installations, although it requires
more framing work.
2. Attach the self-adhesive foam strips
(supplied) to the cabinet wherever
there will be contact with the studs
or sheetrock. Use longer strips for
the sides, and shorter strips for the
front face and the shorter vertical
side.
The procedure for mounting is basically
the same as the vertical mounting.
1. The cabinet should be mounted off
the floor as shown, to prevent nails
from puncturing the cabinet during
baseboard installation.

sible, add a few screws to secure
the bottom face of the cabinet. You
may have to angle them in, but do
not screw in to any of the cabinet
joints. The cabinet walls are 3/4
inch thick, so make sure the screws
do not pass all the way through.
4. Wiring the subwoofer is the same
as described previously, except that
there is not much room to make the
connections to the binding posts.
8. Do an electrical continuity test to
make sure the connections are
good from the amplifier-end of the

Baffle installation procedure
1. Remove the debris shield from the
front of the in-wall cabinet. You can
do this by cutting the cardboard
with a sharp knife and pulling out
the cardboard pieces and the plas-
tic rivets holding it in place. Do not
cut the two wires inside the cabinet,
and do not remove any sound-
proofing material.
4. Secure the woofer baffle assem-
bly to the in-wall cabinet using 14
Allen-head screws and washers
supplied. Make sure the two wires
do not get pinched.

5. Before putting the grille frame and
grille on, test the subwoofer to see
if all the connections are made
correctly. See the user's guide that
comes with your SubRosa ampli-
fier.
2. With the help of an assistant, hold
the baffle assembly close to the
in-wall cabinet.

Grille installation
With the woofer baffle installed, and
the subwoofer tested, the grille can now
be installed.
Painting
The frame and grille can be painted to
match the decor before they are installed.
They come already powder coated, and
can accept a wide range of finishes.
The grille assembly consists of the fol-
lowing components:
•
The grille frame. This screws to the
woofer baffle and holds the grille in
place. It forms a nice frame around
the subwoofer opening in the wall,
hiding the sheetrock edges.
Clean them first, then take them
to a well-ventilated area and paint
with care to achieve a good finish.
If you prefer to paint the frame and grille
when they are in place on the walls, the
details are shown on the next page.

•
The grille. This pushes into the
grille frame, covering the woofer
baffle assembly and the grille frame

A paint shield is supplied to cover
the woofer baffle when painting.
This allows you to paint the frame
and grille at the same time the
walls are painted.
