How to use

Install the GSUB-8 in a stable location protected from direct, prolonged exposure to heavy rain when possible. Connect to a compatible amplifier with appropriate power and impedance matching according to the amplifier and speaker specifications. For balanced system performance, pair the subwoofer with suitable satellite speakers and apply high-pass filtering to satellites and low-pass filtering to the subwoofer as needed. Adjust crossover frequency and gain on the amplifier or processor to achieve a smooth low-frequency blend with the main speakers.

Recommendations

Position the subwoofer on firm, level ground or use weather-resistant mounting hardware where appropriate. Allow adequate ventilation around the enclosure and avoid covering driver ports. Regularly inspect connectors and seals for corrosion or wear after exposure to outdoor conditions, and use a protective cover when the unit is not in use for extended periods.
