Unpacking the System
Carefully unpack the speakers. If there is any sign of damage from transit, report it immediately to your dealer and/or delivery
service. Keep the shipping carton and packing materials for future use.

Placement Options
HS 450 and HS 460 – These speakers are primarily designed as the left and right speakers in both a stereo and a multi-
channel system. Visit Boston Acoustics.com/placement for diagrams explaining the proper placement of loudspeakers.
Bookshelf Models – HS 40, HS 50, HS 60, and HS 225 These speakers are easily placed on a
tabletop, shelf, or wall-mounted. The speakers are congured for tabletop/shelf use when you rst
unpack the system. The HS 225 speaker will have one foot installed that will keep your speaker
level when used in the vertical position. Refer to the diagram below for adjusting the HS 225 for
horizontal use as a center channel speaker.
There are 2 sets of holes on each foot; by using the upper of the two holes,
the speakers will have a slight forward angle for use on a high
shelf. When the feet on the back of your speakers
are removed, the speakers are easy to wall-mount.

The Boston Horizon bookshelf models are designed to easily mount on the wall using the keyhole slot(s) on the back of the
speaker. When mounting the speakers to the wall, use the supplied rubber bumpers. You must remove the attached foot to
wall-mount your speakers. Remove the thumbscrew from the back of the foot. It is slotted for easy removal with a screwdriver
or a coin.
The keyhole mounting option is similar to hanging a picture frame on a wall. Install a screw into the sheetrock, making sure
to go into a stud, and hang the speaker onto the screw head. If a stud is not available a sheetrock anchor should be used to
support the weight of the speaker.

NOTE: You are responsible for the correct selection and use of mounting hardware (available through hardware stores) that
will ensure the proper and safe wall-mounting of the speakers.
Speaker Connections
After your speakers are properly placed, you are ready to wire your system. First, turn o all system power. We recommend
18-gauge wire or thicker for runs up to 25 feet (8m), and 16-gauge wire or thicker for longer runs. Separate the rst few inches
of the wire conductors. Strip o 1/2”(12mm) of insulation from the ends of each speaker wire to expose the two conductors
and tightly twist the wire strands. Please see the illustration below for guidance connecting the wires to your speakers. For
connection to your receiver, please refer to its owner’s manual.

Important!
To ensure the best performance, observe polarities when making speaker connections, (as shown in the illustration).
Connect each + terminal on the back of the amplier or receiver to the respective + (red) terminal on each speaker. Connect
the – (black) terminals in the same way. If the connections are not made correctly it can cause poor bass response and imag-
ing. Also, to avoid short circuits that may damage your equipment be careful not to let any of the bare wires touch each other.
Operation
When using the Horizon speakers in a Dolby® Digital or DTS™ home theater system, make sure all speakers are set to“Small”.
When using the system in a Dolby Pro Logic® home theater system, make sure the receiver’s center channel mode is set to
“Normal.”
Some Dolby Digital-equipped receivers/processors oer dierent setup options for each source or surround mode (e.g., CD-
stereo, videotape, Dolby Digital, Pro Logic). In each case, follow your equipment’s instructions to ensure that the subwoofer
output is turned on and that the speakers are set to “Small” in each mode.
The HS 450 and 460 can be set to “Large”and may produce a more full sound by doing so. Try both settings and use the one
that sounds best with the broadest range of source material.
If your receiver has adjustable crossover settings, we recommend the subwoofer crossover be set between 80Hz and 120Hz.
Refer to the owner’s manual for your AV receiver for any additional recommendations on system operation.
NOTE: A Boston Acoustics powered subwoofer will add impact and realism to both music and lm soundtracks. Contact
your Boston Acoustics dealer for recommendations on subwoofer models for your application.
Wires can be routed through the feet and
the channels in the back of the speaker

Maintenance And Service
All wiring connections should be inspected and cleaned or remade at least once a year.
If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one
loudspeaker, rewire that speaker in a dierent location within the system. Should the problem persist, then the problem is
within the speaker. If the speaker sounds ne in the new position it is a strong indication of a more in depth issue with the
electronics in the system. In the event that your speakers ever needs service, contact your local Boston Acoustics dealer
or visit www.bostonacoustics.com for a list of dealers in your area.
