Installation

Unpack and inspect contents. Ensure proper tools and safety equipment are available.

1. Choose location: Select ceiling location free from obstructions (joists, wiring, pipes).
2. Cut opening: Use template to mark and cut 8.75-inch diameter hole in ceiling.
3. Connect wires: Strip speaker wire ends, connect to terminals (observe polarity: + to red, - to black).
4. Mount speaker: Insert speaker into hole, tighten dog-leg clamps until secure.
5. Attach grille: Snap grille into place after installation.

WARNING! Turn off amplifier power before connecting wires. Ensure ceiling can support speaker weight. Use caution when working overhead.

First-Time Setup

After installation, configure speaker for optimal performance.

1. Adjust tweeter angle: Pivot tweeter to direct sound toward listening area.
2. Test connection: Power on amplifier at low volume to verify sound output.
3. Balance audio: Adjust amplifier settings for proper channel balance if using multiple speakers.
4. Paint grille (optional): If desired, remove grille and paint with light coats of spray paint.

CAUTION! Do not over-tighten mounting clamps. Ensure wires are not pinched during installation.

System Configuration: For multi-room systems, use impedance-matching volume controls or multi-channel amplifier.

Connecting to Audio Systems

Connect to amplifier or receiver using standard speaker wire.

1. Turn off amplifier power.
2. Run speaker wire from amplifier to speaker location.
3. Strip 1/2 inch of insulation from wire ends.
4. Connect positive (+) wire to red terminal, negative (-) to black terminal.
5. Ensure connections are secure and not touching each other.
6. Turn on amplifier at low volume to test.

Tip: Use 16-gauge or thicker wire for runs over 50 feet. Maintain proper polarity for best sound quality.

Operation Guidelines

For optimal performance and longevity:

1. Power sequence: Turn on amplifier last, turn off first.
2. Volume levels: Avoid prolonged operation at maximum volume.
3. Impedance matching: Do not connect more than two pairs of 8-ohm speakers to a single amplifier channel.
4. Environmental conditions: Avoid extreme temperatures and humidity.
5. Tweeter adjustment: Reposition tweeter if listening area changes.

WARNING! Do not exceed recommended power handling. Distorted sound indicates potential damage risk.

Care & Maintenance

Regular maintenance ensures optimal performance.

1. Cleaning: Use soft, dry cloth to dust grille. Do not use liquids or abrasive cleaners.
2. Grille removal: Gently pry edges with flat tool to remove for painting or deeper cleaning.
3. Inspection: Periodically check wire connections for corrosion or looseness.
4. Ventilation: Ensure speaker baffle is not obstructed by insulation or debris.

CAUTION! Never insert objects through grille. Do not use solvents or water for cleaning.
