the user’s favorite listening position minimizing reflections from the side walls. For surround sound or low volume background listening create more reflections and thus more ambi- ence by directing the tweeter towards the side walls.

8.Direct the Woofer. The woofer is direct- ed by gently pushing on the outer edge of the grille face. (See Figure 20). It will move 15° in any direction. For critical listening, point the woofer to the user’s favorite listening position minimizing

reflections from the side walls. For sur- round sound or low volume background listening create more reflections and thus more ambience by directing the woofer towards the side walls.

9.Setting the Treble cut switch. Listen to a well-recorded piece of music at the user’s favorite listening position. Listen for treble harshness or ringing, particu- larly when the loudspeakers are placed in a room without carpet. Use the +/- 1.5dB Treble switch to correct.

10.Setting the bass jumper. Listen to a well-recorded piece of music at the user’s favorite listening position. Listen for bass boominess, particularly when the loudspeaker is placed near a corner. Remove the loudspeaker by grasping the tabs and rotating counter-clockwise. Adjust the bass jumper (-1dB, -2dB) accordingly. (See Figure 21).

11.Install the grille into the loudspeaker. The grilles should fit snugly. If you have difficulty fitting them in, try loosening the mounting dog screws (excessive tightening can distort the shape of the frame holding the grille in place).
