Placement Guidelines

Optimal placement enhances bass performance and room integration.

Corner placement: Maximizes bass output but may cause boominess.

Near-field placement: Provides tighter, more accurate bass response.

Crawl test: Place subwoofer in listening position, crawl around room to find spot where bass sounds best.

Distance from walls: Minimum 2-3 inches for proper ventilation.

Care & Maintenance
