Tightening the mounting “dogs”

install the speaker, first rotate the dogs inward. Insert the speaker into the cutout and tighten the dogs by turning the screws clockwise. DO NOT OVER- TIGHTEN THESE SCREWS. Over-tight- ening the clamps may make the grille difficult to install. (See Figure 17).

NOTE: The screws will be easier to turn if you “prime” them first. Before installing each speaker, turn the screws in and then turn them back out to their original positions.

8.Direct the Tweeter. The tweeter is directed by gently pushing on the edge of the tweeter grille. It will move 20° in any direction. For critical listening point the tweeter to the user’s favorite listen- ing position minimizing reflections from the side walls. For surround sound or low volume background listening cre- ate more reflections and thus more ambience by directing the tweeter towards the side walls. See Speaker Placement on Page 6.

9.Setting the Bass and Treble cut switch- es. Listen to a well-recorded piece of music at the user’s favorite listening position. a) Listen for bass boominess, particularly when the speaker is placed near a corner. Use the -2dB Bass cut to correct. b) Listen for treble harshness or ringing, particularly when the speakers are

placed in a room without carpet/ Use the -2dB Treble cut switch to correct.

10.Install the grille into the speaker. The grilles should fit snugly. If you have diffi- culty fitting them in, try loosening the mounting dog screws (excessive tighten- ing can distort the shape of the frame holding the grille in place).

Painting the Speakers

All models may be painted. The plastic will readily accept most paints.

The speakers must be masked prior to painting them. The inside circular portion of the hole template can be used as a paint mask. Remove the outside portion of the template by gently pulling along the perforation. Affix the mask to the front of the speaker using a piece of tape. Fold the tape onto itself to form a double-sided loop. Affix the tape to the tweeter and place the mask onto the speaker.

The grilles should be painted before they are installed. For all models, the best results will be obtained by using a spray gun or airless sprayer, thinning the paint (prevents clogging of the grille holes), and by applying several light coats instead of one heavy one.

Speaker Phase

Speaker wire has two conductors. One con- ductor is attached to the negative (-) terminals and one conductor is attached to the positive

(+)terminals of both your speaker and your amplifier. Usually, the wire is marked for your convenience. There are different ways wires are marked: a stripe on one wire, a ribbed area of one conductor you can only feel, different colors of metal wire on each conductor, or there might be a fabric strand or string wound into one of the conductors. Of course, there are some wires which appear completely identical. Be careful, or you might make a mis- take.
