1. Binding Posts
The subwoofer has one pair of binding posts for connection with speaker wire to the
output posts of the HRSIW8AMP.
Always use high quality connections and speaker wires, and make sure there are no
loose ttings or stray wire strands. The spring connections accept bare wire or pins.
Connect the positive speaker-level output of the HRSIW8AMP to the positive (red) input
of the subwoofer. Connect the negative speaker-level output of the HRSIW8AMP to the
negative (black) input of the subwoofer.
Make sure that the positive and negative connections do not touch, or this may damage
your power amplier.
2. Speaker Wire Channel
To ease installation, the speaker wiring are passed through these channels to the
binding posts. This is recommended as the channel will support the weight of the
speaker cable, so it does not pull on the binding posts.
3. Clamps
Once the subwoofer is pressed into an opening in the sheetrock, screws on the front
panel are turned to pull the clamps out and down to press against the sheetrock, and
secure the subwoofer in place.

5. Clamp Screws
These six screws are used to clamp the loudspeaker in place once it has been pressed
into the sheetrock opening of your wall.
6. Grille Magnets
The grille is attached to the main body with small magnets around the edge of the
subwoofer bafe.
7. Grille
To remove the grille, gently pry it away from the corners and release it from the magnets
holding it in place. The grill can be painted to match the room decor.
8. Cutout Guide
This guide allows you to easily mark the required cutout onto your wall.

LOCATION
The suggestions below will typically result in outstanding performance. However,
although low frequencies are non-directional, factors such as room reections, standing
waves, resonance and absorption will strongly affect your subwoofer’s performance.
Since your SpeakerCraft subwoofer is designed to be professionally installed into your
wall, engineering services from your authorized SpeakerCraft dealer and/or outside
acoustical resources should be considered to ensure optimum performance.
The HRSIW8AMP’s DSP features will tailor the sound to the room for optimum
performance in the location you choose. Controls include the crossover frequency, and
slope, phase, and subsonic lter.
Preliminary
Before cutting a hole in your wall, it is always best to test the subwoofer in that
location rst. Place it on the oor near to the “possible” location, and connect it to the
HRSIW8AMP. Play some typical bass passages through the subwoofer. This will help
you identify any problems in the sound due to the location, and you may be able to nd
a location that sounds better.
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

9Nortek Security & Control LLC
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.
Using Two Subwoofers
If you wish to use two subwoofers, the sound output will double. Each subwoofer will
need its own dedicated HRSIW8AMP.
Locating the subwoofers on the front wall, with one towards each corner will provide
more exibility in crossover points, without causing localization that can happen with
subwoofers located on side and rear walls. SpeakerCraft pre-ampliers and receivers
feature multiple subwoofer outputs for these applications. If your preamplier has a
single sub/LFE output, use a Y cable to split it into two outputs, one for each amplier.

Speaker Level connections
The amplier’s speaker level outputs can accept speaker wires with banana, dual-
banana, bare wire, pins or spade terminals. If you have banana type connectors on
your speaker wire, make sure that you tighten the binding posts before inserting.
Make sure that the negative speaker wires never touch the positive wires as this will
short out and possibly damage your amplier.
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.

SUBWOOFER INSTALLATION
Read the details on page 8 to help determine the best position for your subwoofer in
the room.
The subwoofer can be wall mounted vertically, centered between vertical wall studs.
This is the recommended (and easiest) orientation to install.
Horizontal mounting into existing construction will most likely mean cutting a vertical
stud. This installation should be done by an experienced and qualied carpenter, to
prevent weakening the wall structure. When the extra framing is done, the installation
and wiring is the same as described below.
Tools required
• Phillips screwdriver
• Pencil or other suitable wall marker
• Sheetrock hand saw
• Safety glasses
• Level
• Masking tape
• Flashlight
• Small mirror
• Electronic stud nder if needed
• You may need an assistant.
Preliminary Steps
• If the TV display is in place nearby, it should be removed from the wall, or at least
turned off and covered.
• Clear the area where you are going to work, so it will be safe. Remove any fragile
objects, small children or pets, and cover anything that might be affected by dust
from cutting sheetrock.
• Put on your safety glasses.

13 Nortek Security & Control LLC
Marking and cutting the opening
1. Choose the best location for your subwoofer, preferably centered between
vertical wall studs. Use a stud nder to nd where the studs are. Do not position
the subwoofer closer than one inch from the cabinet sides to a stud. This allows
for the clamps to swing out.
2. Tape the supplied cutout template onto the wall surface, and use a level to make
sure it is vertical.
3. Mark the sheetrock with a pencil around the inside of the template, and remove
the template.
4. IMPORTANT: Turn off the electricity to the room, just in case you accidently cut
a live AC mains wire.
5. Drill a small pilot hole, and using a ashlight and small mirror, look for any
obstructions such as water pipes, gas lines, or electrical wires that may interfere
with the subwoofer installation.
6. If all is clear, carefully cut out the sheetrock around the marked lines, and remove
any debris from the hole.

Wiring
The HRSIW8AMP has two binding posts for connection to the HRSIW8 subwoofer.
1. Install the speaker wires following all local codes for low voltage 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 if this is not possible, try crossing them perpendicularly. This will reduce the
chance of picking up hum or other interference.
3. If required, pass the wiring through the speaker wiring channels in the back of the
subwoofer.
4. Do an electrical continuity test to make sure the connections are
good from the amplier end of the speaker wire to the ends of
the wires at the subwoofer.
5. Secure the wiring to the loudspeaker’s spring-loaded binding posts, observing
the correct polarity. Gently pull on them to make sure they are secure.
6. 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. Try using heavy duty
electrical staples to hold the speaker cable securely to the studs.

Installing the Subwoofer
1. Press the subwoofer into the sheetrock
opening making sure that the speaker
wires do not get pinched or cut.
Tighening the clamps (sheetrock
not shown, for clarity)
2. Screw in the six clamp screws. As
the screw turns clockwise, a clamp
rotates out and presses onto the
back of the sheetrock to hold the
subwoofer rmly in place. Tighten
the clamps so they are snug, but
do not over tighten, as they could
damage the sheetrock.
Final steps
1. Add the grille to cover and protect the woofers.
2. The grill can be painted if desired, and this best done when it is not attached to
the subwoofer.
3. Enjoy your new subwoofer.

TROUBLESHOOTING
The HRSIW8 subwoofer is designed and built to provide years of trouble-free
performance. Most problems that occur can usually be solved by checking your setup,
or by making sure all components are fully operational.
The following information will help you deal with common problems you may experience.
If a problem persists, please contact your Dealer for assistance.
Poor or no sound
• Check all the connections from the subwoofer to the amplier.
• The speaker is designed to be powered only by the HRSIW8 amplier. No other
amplier should be used as the performance will suffer, and possible damage to
the speaker will occur.
• Check that the amplier is not driven too hard.
• Many processor/preamps can send test tones through all the loudspeakers in
your system. Use this to adjust the volume of each channel until they are all
playing at the same level. Make sure that any bass management options are set
correctly.
• If the system bass is weak only when playing surround sources, check that your
processor is correctly set to decode the surround modes, such as Dolby Digital
or DTS.
• Some DVD discs have a menu that allows you to select which soundtrack to play.
Check that the correct surround audio soundtrack is selected.
