Description

The Boston Bravo™ is a multi-purpose, high performance compact loudspeaker . The Boston Bravo, which uses Boston’s
patented one-inch aluminum dome VR tweeter with AMD and a 4

1

⁄2-inch woofer, can be combined with its supplied

mounting bracket or rear stand to be mounted or placed virtually anywhere in any room.
The Boston Bravo is essentially one-quarter of a cylinder , allowing it to be mounted vertically at any height in a corner, or

horizontally at the top of a wall, where wall and ceiling meet. Attaching the Boston Bravo to any surface is as simple as
mounting the bracket to the wall, removing the grille from the speaker, and then attaching the speaker to the bracket
using the supplied screws. Once the grille is placed back on the speaker, the means of attachment becomes virtually
invisible. Additionally , the Boston Bravo can be placed either horizontally or vertically on any flat surface, such as a table
or a shelf. Horizontally , it can either angle upwar d by r esting on its two corner fillers or sit untilted using the r ear stand.

By virtue of its patented VR tweeter , the Boston Bravo is an economical and appr opriate choice as a surr ound speaker for
any Boston system using similarly equipped main and center channel speakers: VR-M50, 60, 80, 90 and VR-MC; VR940,
950, 965, 975, 910 and 920; MR90x, 100x and 90c. However , since it shar es the Boston Sound

™

with all other Boston
speakers, the Boston Bravo can be used successfully as a surround speaker with any Boston main and center channel
speakers. The Boston Bravo can also be used in conjunction with any of today’s widely available quality loudspeaker
brands.

Because it is designed as a high-performance, general-purpose speaker , the Boston Bravo is suitable for any high-fidelity
application where it is important that the speaker blends into its surroundings. The Boston Bravo is well suited for back­ground and whole house music applications. The Boston Bravo’s highly flexible mounting bracket allows it to be placed in
a wide variety of locations, and to for the speaker to be angled for optimum sound quality and three-dimensional
imaging. When a pair is placed vertically in the corners of a room, the Boston Bravo creates an unusually wide listening
window, providing true ster eo sound r epr oduction over a br oad ar ea.

For full-range applications, it is recommended that the Boston Bravo be used in conjunction with one of Boston’s
powered subwoofers: PV400, 600, 800 or 1000. The Boston Bravo’s low frequency limit is 80Hz, allowing for a great deal of
placement flexibility for the subwoofer . The Boston Bravo’s r obust design allows it be used with full-range signals and
amplifiers rated between 15 and 125 watts. Please note that the Boston Bravo is not magnetically shielded. Therefore, it
should not be placed closer than 18 inches from a tube television. The Boston Bravo may be used safely near projection
and plasma televisions.

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 .
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.

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.

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. Y ou’ll hear a
dramatic change in sound. The connection that yields the fuller bass and louder sound is correct.

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).
