Description

The Boston Bravo™II is a multi-purpose, high performance compact loudspeaker. The Bravo II, 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.

The Bravo II is essentially one-quarter of a cylinder, allowing it to be mounted vertically at any height in a corner, or hori-

zontally at the top of a wall, where wall and ceiling meet. Attaching the Bravo II 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 sup-

plied screws. Once the grille is placed back on the speaker, the means of attachment becomes virtually invisible.

Additionally, the Bravo II can be placed either horizontally or vertically on any ﬂat surface, such as a table or a shelf.

Horizontally, it can either angle upward by resting on its two corner ﬁllers or sit untilted using the rear stand.

Because it is designed as a high-performance, general-purpose speaker, the Bravo II is suitable for any high-ﬁdelity appli-

cation where it is important that the speaker blends into its surroundings. The Bravo II is well suited for background and

whole house music applications. The Bravo II’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 Bravo II creates an unusually wide listening window, providing true stereo

sound reproduction over a broad area.

For full-range applications, it is recommended that the Bravo II be used in conjunction with one of Boston’s powered sub-

woofers. The Bravo II’s low frequency limit is 80Hz, allowing for a great deal of placement ﬂexibility for the subwoofer. The

Bravo II’s robust design allows it be used with full-range signals and ampliﬁers rated between 15 and 125 watts. Please

note that the Bravo II is not magnetically shielded. Therefore, it should not be placed closer than 18 inches from a tube

television. The Bravo II may be used safely near projection and plasma televisions.

Also available; The Boston Bravo II Center. The Bravo II Center is sonically matched to the Bravo II and features

Magnaguard®magnetic shielding allowing for use on or near tube televisions without interference.

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 cor-

rectly 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 II 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.

Mounting the Bravo II

Identify the Bracket

In its packing material, the Bravo II’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 II 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 II 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 speak-

er wire through a conduit.

Using the Bravo II on a Flat Surface

The Bravo II 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.

Corner Fillers

If the Bravo II is being mounted in a corner, then one or both of the supplied

corner ﬁllers may be inserted into the slots on the back of the speaker. These

accessories will enhance the appearance of the installation by making it appear that

the back of Bravo II extends into the corner.

NOTE: Up to 16-gauge speaker wire will ﬁt between the ﬁllers and the corner.

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,

1⁄2-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” and “Basic Hookup” on page 3). Both the Bravo II 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.

Rear Stand Installation Instructions

The Boston Bravo can be used horizontally on an untilted ﬂat

surface, such as a table, shelf or the top of a rear projection

TV using the included rear bracket stand.

First mount the speaker to the bracket (see above).

Next, place the speaker in the location that you intend to use

it in (ie, correct grille/logo and tweeter/woofer orientation).

Hold the stand in an upright position as indicated (note that

the stand angles away from the bracket). Line up the stand

with the lower slot in the bracket so that the 2 middle “ﬁn-

gers” are on either side of the web that bisects the slot.

Slightly angle the stand away from the bracket and push the

stand ﬁngers up into the slot so that the 4 inner “ﬁngers” are

placed inside the slot and the 2 outer “thumbs” are placed

outside the slot. Gently push the stand up into the bracket

slot until the “ﬁngers” and “thumbs” snap into place.

Attach the rubber feet to the stand and cabinet (detailed on page 4).

Ceiling Clearance

If the Bravo II is to be mounted so that the

top or the side of the speaker will meet a

ﬂush surface, either a wall (horizontally) or

the ceiling (vertically), then measure the

exact distance as shown here from that sur-

face to the top or side of the bracket.

Mount the Speaker to the Bracket

Remove the speaker’s grille by grasping the back of the

cabinet in one hand, while gently pulling the grille away

with the other hand.

Align the openings in the back of the speaker with the

two posts protruding from the bracket as shown below.

Gently remove any slack in the speaker wire as you push

the speaker ﬁrmly onto the bracket.

Attach the speaker to the bracket by inserting the

supplied screws through the holes in the front of the

speaker and into the bracket as shown below (do not

over-tighten the screws).

Replace the grille on the speaker.

NOTE: The Bravo II is not securely attached to its bracket

unless the screws are used.

Using the Bravo II as a Main Speaker

The Bravo II can provide exceptional performance from 80Hz and above. For deep bass reproduction, a pow-

ered subwoofer might be a suitable addition to the Bravo II. In small or medium size rooms, two Bravo IIs should

provide ample volume, given appropriate ampliﬁer power of between 15 and 125 watts. In larger spaces, addi-

tional Bravo IIs may be necessary.

For broad, stereo coverage, vertical corner mounting of the Bravo II will produce excellent results. This tech-

nique will work especially well in situations where the distance between the two speakers is approximately 12 to

18 feet.

Using the Bravo II as a Surround Speaker

Two Bravo IIs can be used as surround speakers for Dolby®Surround, Dolby® Pro Logic®, Dolby®Digital and DTS®

surround sound formats. A third or fourth Bravo II can be added for use with Surround EX and DTS®ES surround

sound formats. In general, best results will be obtained when the surround speakers are placed above ear level and

either behind or beside the listening area. However, if attaching speakers to the wall is not an option, then the

Bravo IIs can be placed horizontally directly on the ﬂoor. Since the low frequency limit of the Bravo II is approxi-

mately 80Hz, speaker bass management should be set to "small." This will redirect the surround channels’ bass

information to either the system’s subwoofer or main speakers. Please consult your surround sound electronics

owner’s manual for additional information about speaker placement and bass management

Rotating the Logo for Horizontal Mounting or Placement

The logo plate on the Bravo II’s grille can be rotated 90° in either direction to enhance the speaker’s appearance

when mounting or placing it in a horizontal position. To rotate the logo:

Remove the grille and turn it over.

Locate the logo’s spring loaded post protruding

through the bottom inside portion of the grille.

Place your thumb against the post and press

ﬁrmly until the logo pops forward.

Rotate the logo to the desired position and

release pressure on the post allowing it to snap

back into the seated position.

Listening Levels and Power Handling

The listed power recommendations in the Speciﬁcations section assume you will operate your system in a way that

will not produce distortion. Even these rugged speakers can be damaged by a modest ampliﬁer if it produces

distortion. If you hear a harsh, gritty noise, turn down the volume. Prolonged or repeated operation of your speak-

er with a distorted signal from the ampliﬁer can cause damage that is not covered by the warranty.

If Service Seems Necessary

First, contact the dealer from whom you purchased the speakers. If that is not possible, write to:

Boston Acoustics, Inc. 300 Jubilee Drive Peabody, MA 01960 U.S.A.

We will promptly advise you of what action to take. If it is necessary to return your speaker to the factory, please

ship it prepaid. After it has been repaired, we will return it freight prepaid in the U.S.A. and Canada.
