How to Connect Your Speakers Correctly wiring your speakers is important for achieving the best sound quality. Wiring should takejust 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.
Using the Boston Bravo on a Flat Surface The Boston Bravo can be used on a flat surface, such as a table, shelf or the floor. For horizontal placement that tilts up at 45°, 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" on page 6 and the" Rear Stand Installation Instructions" in the enclosed bag that contains the stand).
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, 112-inch diameter to clear the toggle bolts for hollow surfaces or small enough to allow self-tapping screws in a solid surface).

Using the Boston Bravo as a Surround Speaker Two Boston Bravos can be used as surround speakers for Dolby® Surround, Dolby@ Pro Logic®, Dolby® Digital and DTS® surround sound formats. A third or fourth Boston Bravo 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.
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 thewarranty.
