Using Dipole Speakers
You can use dipole speakers for the surround and surround back speakers. Dipole
speakers output the same sound in two directions.
Dipole speakers typically have an arrow printed on them to indicate how they should be
positioned. The surround dipole speakers (A) should be positioned so that their arrows
point toward the TV/screen, while the surround back dipole speakers (B) should be
positioned so that their arrows point toward each other, as shown.
Using a Powered Subwoofer
To find the best position for your subwoofer, while playing a
movie or some music with good bass, experiment by placing
your subwoofer at various positions within the room, and
choose the one that provides the most satisfying results.
Tip
• If your subwoofer is unpowered and you’re using an external
amplifier, connect the subwoofer pre out jack to an input on the
amplifier.
