Painting the Grille

For best results, it is recommended that the grille be painted with a spray applicator to enable the paint to be evenly applied to the inside edges of the grille’s perforations.

The following items are required to paint the grille:

•the grille (included)

•replacement scrim cloth (included)

•spray paint

•paint thinner (and cloth)

•rubbing alcohol (and cloth)

•white or neutral color water-based primer

•masking tape

•spray adhesive

CAUTION: The grille must be painted before it is attached to the frame.

To Paint the Grille:

1.Remove the grille from the grille filler.

2.Remove the scrim cloth on the inside surface of the grille. If necesssary, slightly peel up the lower inside edges of the black felt strips to remove the scrim.

3.Inspect the inside surface of the grille to ensure that there are no remnants of the scrim cloth. If neces- sary, remove any remnants by rub- bing with a cloth dampened with paint thinner.

4.Clean the front grille surface with a cloth dampened with rubbing alcohol.

5.Apply masking tape over the black felt strips around the grille perimeter to shield them from paint. Be sure to mask only the felt and not the outer metal edges of the grille, so that they will be painted.

6.Apply one coat of the primer and let it dry.

7.Thin the paint before application.

8.Apply one to two coats of spray paint. Use a varied spraying angle when spraying, to ensure paint is applied to the inside edges of the grille perforations.

After the paint is dried, install the replacement scrim cloth, if desired.

To Attach the Replacement Scrim Cloth:

1.Place the grille face down on a soft surface.

2.If paint thinner was used to remove scrim remnants, apply a light coating of a spray adhesive to the inside grille surface. Avoid spraying adhe- sive onto the felt strips. If too much adhesive is used, it could wick into the cloth and degrade the sound.

3.Place the replacement scrim cloth in the grille with the cardboard side facing upward (so that the cardboard is not visible through the front of the grille).

4.Tuck the outer edges of the scrim cloth cardboard frame under the black felt strips and gently smooth the scrim cloth over the grille surface to remove any wrinkles.

Attaching the Grille to the Frame

To Attach the Grille:

1.Line the grille up to the frame and press the grille in only partially at first.

2.Push gently at multiple points around the outer edges to slowly ease it into position.

NOTE: Configure the four front-panel controls and experiment until optimal results are achieved, before installing the grille.

Grille Removal

To Remove the Grille:

1.Insert the small end of the included 1/16-inch Allen key into one of the metal mesh holes in the top corner of the grille, as shown in Figure 20.

2.With the end of the Allen key in the grille hole approximately 1/8 inch, with thumb and forefinger close to the grille, pull up on the Allen key to wedge it into the grille hole.

3.Gently pull the Allen key to partially pop out the corner of the grille.

4.Repeat Steps 1 to 3 for the other top corner.

5.Apply Steps 1 to 4 for the bottom corners.

6.When all corners are partially popped out, the grille can easily be removed.

CAUTION: Do not attempt to pry the grille out using the Allen key (or any other object) as a pry bar against the plastic frame.This will cause damage to the frame and mar the paint.

Speaker Frame Removal

To remove the speaker frame from wall opening:

1.Fully unscrew all of the clamps around the speaker housing. The clamp screws have an acorn nut attached on their end to prevent accidental disassembly.

2.Move the speaker housing away from the wall enough to wedge your hand behind and pinch a clamp shut.

3.While the clamp is shut, work the speaker housing forward enough to catch the shut clamp in the wall opening.

4.Work around the perimeter, carefully closing each clamp and then slowly pull the speaker housing from the wall.

LOUDSPEAKER VOLUME LEVELS

High-order filters include steep cut-offs to reduce potential damage from “out- of-band” frequencies. Combined with carefully selected transducers and fil- ter network components, this approach helps the P81/P941 to maintain its per- formance under extreme operating conditions.

However, all loudspeakers have limits when it comes to continuous playback. To extend these limits, avoid playback at volume levels that distort or strain sound.
