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 4½-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 ½-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 ¼-inch, exposing the hole. Insert the wire in
the hole and release the terminal.
