Tip: Ensure polarity is maintained (positive to positive, negative to negative) for proper stereo imaging.

Placement and Room Optimization

Optimal speaker placement significantly enhances performance.

1. Bass Module: Place in a corner or against a wall to reinforce bass frequencies. Avoid exact center of a wall.
2. Satellite Speakers: Position at ear level when seated. Angle slightly toward the primary listening position.
3. Stereo Pair: Place left and right satellites equidistant from the listening position, forming an equilateral triangle.
4. Surround Channels (if applicable): Place to the sides or slightly behind the listening position.
5. Experiment with placement: Small adjustments can dramatically improve soundstage and imaging.

WARNING! Do not place satellite speakers where they may fall. Secure wall mounts properly.

Care & Maintenance

Unplug the system from power before cleaning. Use a soft, dry cloth to wipe exterior surfaces. Do not use liquids, solvents, or abrasive cleaners.

CAUTION! Never allow moisture to enter any openings. Keep the bass module vents clear of obstructions for proper cooling.
