Speaker connections – Boston Acoustics Horizon Series HS225 User Manual

Page 5

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 off 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 fi rst few inches

of the wire conductors. Strip off

” (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.
