OWNER’S MANUAL

Bravo 20

HigH performance multi-purpose speaker

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.

Mounting the Bravo 20

Identify the Bracket

In its packing material, the Bravo 20’s

mounting bracket is ﬁtted into the back

of the speaker. Remove the tape that is

temporarily holding the bracket to the

speaker, and then pull the bracket away

from the back of the speaker.

Determine

how the Bravo 20 is to be mounted to the

wall or ceiling. It can be mounted either

horizontally or vertically, either on an open

section of wall, or where two or three room

surfaces meet. Refer to the illustration here to

determine what screw holes on the Bravo 20

bracket should be used for your application.

NOTE:

The large rectangular hole in the

middle of the bracket will ﬁt a single gang

electrical outlet to route the speaker wire

through a conduit.

Mount the Bracket to the Wall

Decide where to mount bracket.

IMPORTANT: See “Ceiling Clearance” on page 6.

Determine what mounting holes in the bracket will be used.

Mark the holes on the wall or ceiling using bracket as a template.

Drill the holes using the appropriate drill bit size to accommodate the mounting hardware that you plan to use (ie, ½-inch

diameter to clear the toggle bolts for hollow surfaces or small enough to allow self-tapping screws in a solid surface).

Mount the bracket ﬂat or into a corner as shown below. We recommend the use of four fasteners wherever possible. Consult

a knowledgeable installer regarding the proper hardware to use on your wall.

Strip the speaker wires ends, and feed the speaker wire through the appropriate bracket opening.

Connect the wire to the speaker’s terminals, taking care to maintain speaker polarity. (See “How to Connect Your Speakers” on

page 2). Both the Bravo 20 and its bracket are symmetrical, so the speaker can be mounted with either its woofer or tweeter

on top. In general, bass performance will be enhanced with the woofer as close to as many room surfaces as possible.
