SW8
IN-WALL SUBWOOFER
Installation & Operation Manual
Introduction
Congratulations on your purchase of the Destination Audio SW8 in-wall
subwoofer! Your subwoofer is the result of many years of research and
development dedicated to producing high quality products for home audio
systems. This installation manual is designed to provide you with the information
necessary to the SW8 subwoofer’s installation and operation.
Technology
The SW8 features two eight-inch Poly Graphite woofers. Poly Graphite is used
due its stiffness, low mass and self damping properties, the combination of
which allows a virtually uncolored presentation of acoustic material. A powerful
magnet and extended voice coil give the woofers high excursion capability,
which ensures dynamic and accurate audio reproduction.
Crossover Network
The SW8 utilizes an optional low-pass crossover network. This network is a
xed, 100Hz low-pass lter which is active when the switch on the face of the
SW8 is set to “On” as in Figure 1. When the SW8’s crossover switch is on, only
frequencies 100Hz and below will
be reproduced by the SW8, and
all frequencies above 100Hz will
be “ltered” or reduced by 12dB
per octave. When the switch is
set to “Off”, frequencies above
100Hz will not be filtered and
the subwoofer will reproduce
frequencies up to 180Hz. The Figure 1
Crossover set to “On”

crossover switch should be in the “On” position when the audio signal sent
to the subwoofer is ‘full-range’ and not already ltered through another cross-
over. The switch should be set to “Off” when the audio signal being sent to
the subwoofer has already been ltered or crossed-over, such as the subwoofer
pre-out from some A/V receivers and pre-ampliers. Please refer to you’re A/V
receiver or pre-amplier’s owners manual for proper bass management set-
tings information. Proper adjustment of bass management settings will ensure
the subwoofer is not receiving a signal ltered through two crossovers and will
allow the SW8 to perform at its best. Destination Audio suggests consulting
with your dealer or installer, and experimenting with the crossover on and off
to determine which is best for your system.
Installation
Your Destination Audio SW8 in-wall subwoofer has been designed to make
its installation as easy as possible.
The rst step is to locate where you’ll be installing the SW8 and cut the drywall
according to the cutout specications included in this manual. For your
convenience, a cutout template is supplied with the SW8 to assist in helping
you decide where to install it. Warning! Be careful and take your time during
this step. Electrical and plumbing objects within the wall may interfere with the
installation of the SW8. Properly installing the speaker in an area free from objects
such as these will make your installation experience much better. If you’re
fortunate to have used a Destination Audio IBSW8Q new construction bracket,
your cutout will already be located and ready to go for the next steps.
The next step would be to locate the speaker wires which have been run to the
speaker location and connect the speaker wires to the terminal connections on
the rear of the SW8. The positive conductor of the wire connects to the red
terminal and the negative conductor of the wire connects to the black terminal.
Caution! Pay special attention to the Wiring section of this manual for monaural
and stereo amplier connections before proceeding.
The SW8 subwoofer is secured by eight dog leg brackets.
When tightened, these brackets rmly attach the subwoofer
to the drywall. Before inserting the SW8 into the drywall
cutout, check each of the dog leg brackets to make sure
they are ready and appear as in Figure 2. Once the dog
leg brackets are ready or ‘cocked’, insert the SW8 into
the drywall cutout. Using a screwdriver or drill/driver,
tighten each of the eight mounting screws on the front
of the subwoofer. Tightening each of these screws will
rotate the dog leg brackets into position as in Figure 3,

cinching them to the drywall and securing the speaker.
Tighten the screws until each is snug. Caution! Do not
over-tighten the mounting screws as this may cause the
grill to be difcult to install or may cause damage to the
subwoofer’s frame. If you’re using a drill/driver, set the
clutch to a lower setting to prevent over-tightening and
possible damage to the frame. If you’re using hand tools,
tighten just until snug.
Wiring
When wiring for a monaural or single-channel amplier,
connect the positive lead to one of the red (positive)
terminals and the negative lead to the black (negative)
terminal on the same set of terminals, then run a set of
speaker wires to the opposite set of terminals, observing
polarity as in Figure 4. This is a parallel wiring connection,
and this conguration for the SW8 will yield a 4 Ohm
load. Warning! If your monaural amplier is not stable
to 4 Ohms, you need to use a series
configuration to prevent damage to
your amplier.
If you need to make a series connection
from your monaural amplier, please refer
to Figure 5. Connect the positive wire
from the amplier to one of the positive
terminals on the subwoofer. Connect
the negative wire from the amplier to
the negative terminal on the other set
of connections. Then connect a wire
from the remaining positive terminal to
the remaining negative terminal. This
is a series wiring connection, and this
conguration for the SW8 will yield a
16 Ohm load.
When wiring for a stereo amplifier,
connect one set of leads to each set
of terminals, observing proper polarity.
This will connect each woofer individually
as an 8 Ohm load.

Technical Specications
Destination Audio in-wall speaker frames and grilles can be painted any color
to match any décor. A plastic paint shield is supplied and placed inside the
grille to protect the speaker from becoming damaged during painting. Caution!
It is unwise to use a paint roller to paint the grille; doing so will clog or plug the
holes in the grille. PLEASE NOTE: This plastic paint shield must be removed
before operation of the speaker begins.
