4.There are four clamps “dogs” which hold each speaker in place. Rotate all the dogs inward.

5.Insert the loudspeaker into the cutout in the ceiling.

6.The dogs are tightened via four front-baffle screws. Tighten the dogs by turning the screws clockwise, while pressing the loudspeaker against the ceiling. NOTE: DO NOT OVER TIGHTEN THESE SCREWS. Over- tightening the screws may make the grille difficult to install.

8.Install the grille into the speaker.

9.Repeat this procedure for the next speaker.

Directing the Tweeter:

The tweeter is directed by gently pushing on the outside edge of the tweeter grille. It will move 20° in any direction. For critical listening, point the tweeter to 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 ambience by directing the tweeter towards the side walls.

Removing the Grilles:

To remove the grille from the LSC-8, obtain a small paper clip (size #1, common) and bend the last quarter inch of it into an “L” shape.

Holding the paper clip with a pair of pliers, insert the end with the “L” into a hole near the edge of the grille. Remove the grille by pulling the paper clip towards you.

Painting the Speakers:

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.

Painting the Grilles:

The LSC-8 grille should be painted before they are installed on the speakers. The best results will be obtained by using a spray gun or airless sprayer. Thin the paint, and then apply several light coats. This technique helps prevent clogging of grille holes. Paint both sides of the grille to cover all the white paint.

OPERATION

Listening at Higher Volumes

It requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion.

Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good speaker, turn the volume down immediately! You are much less likely to damage a speaker with a large amplifier because it will be more difficult to produce clipping distortion.
