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.
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
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.

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

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 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,
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.

Corner Mount Example
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.

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
Replace the grille on the speaker.
NOTE: The Bravo II is not securely attached to its bracket unless the screws are used.
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 “ﬁngers” 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 placedoutside 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).

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 approximately 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
Using the Bravo II as a Main Speaker
The Bravo II can provide exceptional performance from 80Hz and above. For deep bass reproduction, a powered 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, additional Bravo IIs may be necessary.
For broad, stereo coverage, vertical corner mounting of the Bravo II will produce excellent results. This technique will work especially well in situations where the distance between the two speakers is approximately 12 to 18 feet.
Mounting Possibilities of the Bravo II
We designed the Bravo II to be mounted or placed in a wide variety of conﬁgurations. Shown below are seven of the most common possibilities for you to consider.
horizontal flat mount
front main corner mount
(or any other corner)
with rear stand
rear surround angled down
horizontal floor or shelf placement
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 speaker with a distorted signal from the ampliﬁer can cause damage that is not covered by the warranty.
