Introduction
thank you for choosing Boston acoustics. the Boston Bravo® 20 is a multi-purpose, high performance compact loudspeaker.
the Bravo 20, which uses Boston's patented one-inch aluminum dome Vr® tweeter with amD and a 41⁄2-inch woofer, can be
combined with its supplied mounting bracket or rear stand to be mounted or placed virtually anywhere in any room.
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 1⁄2-inch (12mm) of insulation from the ends of each 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.
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.

Using the spring terminal posts: the spring terminal
posts permit easy connection to banana plugs, spade lugs,
and bare wire. push the the top of the terminal down by
approximately 1⁄4-inch, exposing the hole. insert the wire in
the hole and release the terminal.
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).
4. if using the Bravo 20 with a subwoofer, set the receiver's bass management to small in the speaker setup menu. this will
divert very low frequencies away from the center channel to the main speakers and/or subwoofer.

Using the Bravo 20 on a Flat Surface
the Bravo 20 can be used on a flat surface, such as a table, shelf or the floor. for horizontal placement that angles up at 45º,
both corner fillers must be used and the bracket must be removed. for untilted horizontal placement, the rear stand must be
used with the mounting bracket attached (see "mount the speaker to the Bracket" and the "rear stand installation instructions"
found on page 6. for vertical applications mount the four supplied rubber feet to the bottom of the speaker. attach two of
the supplied self-adhesive rubber feet so that its edge contacts the back edge of the cabinet. apply two more self-adhesive
rubber feet to the recesses at the front of the cabinet.
