3.Remove the speaker grille. Carefully pry each corner with an awl or a small screwdriver.

4.Prepare the speaker/bracket assembly for installation as shown.

For new construction, an optional bracket (Model 35UB for the 251, Model 36CB for the 261) is available from your Boston Acoustics dealer.

5.Route the speaker wire through the cable clamp and connect the wire to the speaker.

WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections to the speaker.

IMPORTANT: Typically, one side of the wire is smooth. Connect this side to the – (black) speaker terminal. The other side has a rib or stripe. Connect this to the + (red) speaker terminal. Connect wire at the amplifier in the same way. Failure to do so will result in degraded sound.

6.Install the speaker according to the diagram below.
