Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components to loosen and reach their optimal performance characteristics.
5.2 Strømhåndtering
The subwoofer has an RMS power rating of 1000 Watts and a MAX power rating of 2000 Watts. Ensure your amplifier's output matches these ratings to prevent underpowering or overpowering, both of which can lead to damage.
5.3 Amplifier indstillinger
Properly adjust your amplifier's gain, crossover, and bass boost settings. Start with low gain and gradually increase it until the desired volume is reached without distortion. Set the low-pass filter (LPF) to prevent high frequencies from reaching the subwoofer, typically between 60-100 Hz, depending on your system's other speakers.
6. Vedligeholdelse
Regular maintenance ensures the longevity and performance of your subwoofer:
- Rensning: Use a soft, dry cloth to clean the cone and surround. Avoid using harsh chemicals or excessive moisture.
