AudioSource Aiming the Tweeter, Painting the Speaker, Removing the AC515W Speaker

Next make sure that the clamps are positioned inside the frame of the speaker.

Clamp

With the grill removed, place the speaker in the wall opening. Make sure that the speaker wire is not hanging against the speaker where it can vibrate and rattle as the speaker reproduces your music.

Next, one at a time, turn each of the six screws that operate the clamps counter clockwise a few turns until you feel the clamp is loose from its resting position. Now turn the screw clockwise until you feel the clamp contact the wall surface.

Tighten all six of the mounting screws in the same manner until the speaker is properly aligned and held tight to the wall surface. Caution: Do not over tighten!

Aiming the Tweeter

Carefully place your fingertips at the plastic edges of the tweeter housing.

Using gentle pressure, swivel the tweeter to aim the axis of the tweeter toward the listening area. You can use a piece of music with a solid center-imaged vocalist to assist in correctly aiming the tweeter. When the tweeters are properly aligned, you will hear a coherent and stable center image from your listening position. Usually, it is sufficient to aim the tweeter only as it handles the frequencies that control the direction of individual sounds in your audio program material.

Painting the Speaker

A paint shield is included in each AC515W speaker package. Place the paint shield inside the frame to protect the speaker. You can now safely paint the speaker frame to match your wall surface if you desire.

When painting the grill caution should be taken to ensure that paint does not clog or congest the perforated openings in the grill. This would prevent proper operation of the grill by restricting the airflow from the individual drivers in the speaker.

Removing the AC515W Speaker

Should it ever become necessary to remove the AC515W speaker from the wall, simply remove the grill and turn the six mounting screws counter-clockwise until you feel the clamps lock out of position in their resting flange. The speaker should easily come out of the wall for service or replacement.

Grill Removal (if installed)

Locate a small hook tool (available at most auto parts stores or home improvement shops, resembling a dentist’s pick- a bent paper clip or stiff wire will work as well), hook the metal mesh of the grill near a corner or edge and gently pull it towards you. Only lift the grill 1/4" (6mm) at this location. Move the tool 1-2" (25-50mm) and repeat until the grill can be removed without damaging it (Figure 7).

Recommended Speaker Wire Gauges

The resistance of the speaker wire in your installation can cause your speakers to perform at less than their optimum quality level. Excess resistance caused by using an undersized speaker wire can result in loss of detail and definition in the bass region of your audio program, as well as loss of dynamic range. Over extremely long wire runs you may even experience loss of high frequency content in the audio signal.

To prevent sonic degradation in your AC515W speaker installation, total speaker wire resistance should be kept below 0.5 ohms. The following table lists recommended speaker wire gauge versus wire run length.

50’ or less - 16 Gauge 2-Cond. CL3 Rated 50’ - 150’ - 12 Gauge 2-Cond. CL3 Rated 150’ - 200’ - 10 Gauge 2-Cond. CL3 Rated
