How to Connect Your Speakers
Correctly wiring your speakers is important for achieving the best sound quality. Wiring should take just a few
minutes, but it's important to do it carefully, since incorrect wiring (such as reversed connections) can result in a poor
soundstage and poor bass.
We recommend 18-gauge wire or thicker for runs up to 15 feet (4.5m), and 16-gauge wire or thicker for longer runs.
Separate the first few inches of the wire conductors. Strip off
speaker wire to expose the two conductors and tightly twist the wire strands.
WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections
to the speaker.
When making all connections, be sure to connect the + (red) on the speaker to the + (red) on the amplifier, and the
– (black) on the speaker to the – (black) on the amplifier.
IMPORTANT: Typically, one side of the wire is smooth.
Connect this side to the – (black) connection. The
other side has a rib or stripe. Connect this to the
+ (red) connection.
Checking the Speaker Connections
It is important that your speakers are hooked up with similar polarity or "in phase." A simple listening test will tell
you if your speakers are connected properly. Place the speakers face to face, as closely together as possible. While
listening to music with your amplifier set to MONO, reverse the connections at one speaker only. You'll hear a
dramatic change in sound. The connection that yields the fuller bass and louder sound is correct.
Connecting the Boston Bravo to Your Amplifier or Receiver
1. Connect the speaker terminals to the amplifier
speaker outputs.
2. Make sure the speaker cable is correctly routed
through the mounting bracket.
(see Mounting Options)
3. When making all connections, be sure to connect
+ to + (red) and – to – (black).
