Setup and Installation

Proper installation is crucial for the best performance of your OSD ACE800 speakers. Please follow these steps carefully.

1. Planning and Placement

Determine the ideal location for your in-ceiling speakers. For optimal sound dispersion, consider placing them equidistant from the primary listening area. Ensure there are no obstructions within the ceiling space, such as electrical wires, plumbing, or structural beams.

2. Cutting the Opening

Use the provided template (if included, or refer to the speaker's cutout dimensions) to mark the circular opening on your ceiling. Carefully cut the hole using a drywall saw or rotary tool. The cutout diameter for the ACE800 is approximately 9.5 inches (24.13 cm).

3. Wiring the Speakers

Run high-quality speaker wire (e.g., 12 or 14 gauge) from your amplifier or receiver to the speaker locations. Ensure proper polarity (+ to + and - to -) when connecting the wires to both the speaker terminals and your audio equipment. The ACE800 speakers have spring-loaded terminals for easy connection.

4. Mounting the Speakers

Once wired, insert the speaker into the cutout. The speaker features dog-ear clamps that will secure it to the drywall. Tighten the screws on the front baffle of the speaker. As you tighten, the clamps will pivot outwards and firmly grip the ceiling material. Do not overtighten.

5. Attaching the Grille

The ACE800 features a magnetic grille. Simply align the grille with the speaker baffle, and the powerful magnets will snap it into place, creating a flush and trimless appearance. The grille can be spray painted to match your ceiling color for complete visual integration.

Operating Your Speakers

Once installed, your OSD ACE800 speakers are ready for use. Connect them to a compatible amplifier or home theater receiver to enjoy high-fidelity audio.

Adjusting the Pivoting Tweeter

The 1-inch PEI dome tweeter on your ACE800 speakers can be pivoted to direct sound towards your primary listening area. Gently push the edge of the tweeter to angle it as desired. This feature allows you to fine-tune the soundstage for optimal clarity and imaging, especially in rooms where direct speaker aiming is not possible.

Power Handling

The ACE800 speakers are designed to handle up to 120 watts of power. Ensure your amplifier's output does not exceed this rating to prevent damage to the speakers. Always start with a low volume and gradually increase it to a comfortable listening level.

Maintenance

Your OSD ACE800 speakers require minimal maintenance to keep them performing optimally and looking great.

Cleaning

To clean the grilles and speaker frames, use a soft, dry cloth. For stubborn dust or light smudges, a slightly damp cloth can be used, but ensure no moisture enters the speaker components. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish or speaker materials.

Painting the Grille

The magnetic grilles are paintable. If you wish to match them to your ceiling color, use a fine-mist spray paint. Apply several thin coats rather than one thick coat to avoid clogging the grille perforations, which could affect sound quality. Allow each coat to dry completely before applying the next.

Troubleshooting

If you encounter any issues with your OSD ACE800 speakers, refer to the following common troubleshooting steps:

• No Sound:
  • Check all speaker wire connections at both the speaker and the amplifier/receiver. Ensure proper polarity.
  • Verify that the amplifier/receiver is powered on and set to the correct input source.
  • Test with another audio source or speaker to isolate the problem.
• Distorted Sound:
  • Reduce the volume level on your amplifier/receiver. Overdriving the speakers can cause distortion.
  • Check speaker wire connections for loose strands or short circuits.
  • Ensure the amplifier's power output does not exceed the speaker's maximum power handling.
• Uneven Sound or Poor Imaging:
  • Adjust the pivoting tweeter on each speaker to direct sound towards your listening position.
  • Verify that both speakers are wired with correct polarity. Reversed polarity on one speaker can cause phase issues.

If the problem persists after trying these steps, please contact OSD Audio customer support for further assistance.
