Operating Your Subwoofer Enclosure
Manipulació de potència
The SDR-3X8D2 enclosure has a Peak Power rating of 2,100 Watts and an RMS (Root Mean Square) Power rating of 1,050 Watts. When selecting an amplifier, ensure its RMS output matches or is slightly below the subwoofer's RMS rating to prevent damage and ensure optimal performance. Avoid exceeding the maximum power rating.
Afinació i rendiment
This ported enclosure is factory-tuned at 46 Hz, providing a balance of deep and accurate bass response. Proper amplifier gain settings and crossover adjustments are essential for achieving the desired sound quality and protecting the subwoofers. Consult your amplifier's manual for guidance on setting these parameters.
