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 amplier.
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.

LOCATION
The suggestions below will typically result in outstanding performance. However,
although low frequencies are non-directional, factors such as room reections, 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

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-ampliers and receivers
feature multiple subwoofer outputs for these applications. If your preamplier has a
single sub/LFE output, use a Y cable to split it into two outputs, one for each amplier.

LOCATION
Speaker Level connections
The amplier’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 amplier.
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.
