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.
