Installation

Unpack and inspect contents. Choose optimal placement for best sound performance.

1. Position speakers: Place on stable surfaces away from walls (minimum 6 inches).
2. Connect speaker wire: Strip insulation, connect to amplifier/receiver binding posts.
3. Polarity: Ensure positive/negative connections match on both ends.
4. Room placement: Position at ear level for optimal listening experience.

WARNING! Speakers are heavy; use proper lifting technique. Ensure secure placement to prevent tipping.

First-Time Setup

Connect to amplifier/receiver and configure for optimal performance.

1. Amplifier connection: Connect speaker wires to amplifier's speaker outputs.
2. Polarity check: Ensure red to red (+), black to black (-) connections.
3. Initial testing: Play audio at low volume to verify proper operation.
4. Position adjustment: Fine-tune speaker placement for best sound staging.

CAUTION! Do not exceed recommended power handling. Start with low volume levels.

Receiver settings: Speaker size (large/small), crossover frequency, distance calibration, channel levels. Bi-wiring capability: Use separate cables for high and low frequencies if amplifier supports.

Connecting Devices

Connect to various audio sources via amplifier/receiver.

1. Turn off all equipment before making connections.
2. Use quality speaker wire (16-gauge minimum for long runs).
3. Connect to amplifier's speaker outputs matching impedance requirements.
4. For home theater: Connect as front left/right channels in surround setup.

Tip: Use banana plugs for secure, reliable connections to binding posts.

Audio Optimization

Fine-tune speaker performance for your listening environment.

1. Toe-in adjustment: Angle speakers slightly toward listening position.
2. Distance from walls: Adjust for optimal bass response.
3. Room treatment: Use rugs, curtains to reduce reflections.
4. Break-in period: Allow 20-30 hours of play for drivers to settle.
5. Listening height: Position tweeters at ear level when seated.

WARNING! Avoid placing near heat sources or in direct sunlight.

Room Calibration

Use room correction systems for optimal sound quality. Many AV receivers include auto-calibration features. Manual adjustment: Use test tones and SPL meter for precise level matching.

Care & Maintenance

Regular cleaning preserves appearance and performance. Use soft, dry cloth for cabinet. Gently vacuum grille cloth if needed. Avoid liquids and abrasive cleaners.

CAUTION! Do not remove driver units. Professional service required for internal repairs.
