• Rōrahi: Adjusts the overall output level of the subwoofer. Start with a moderate setting and fine-tune during calibration.
• Tere Toha Iti: Controls the upper frequency limit of the subwoofer. Set this to blend smoothly with your main speakers. A common starting point is 80Hz, but it may vary depending on your main speakers' low-frequency extension. If using a receiver with bass management, set the low pass filter on the subwoofer to its maximum setting (or LFE if available) and manage crossover frequencies through your receiver.
• Phase Control (0/180°): Adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both 0° and 180° settings to achieve the most impactful and coherent bass. The correct setting will result in stronger, more defined bass at the listening position.

3. System Calibration

For optimal performance, it is highly recommended to calibrate your subwoofer with your audio system. Many modern AV receivers include automatic room correction systems (e.g., Audyssey MultEQ XT32) that can simplify this process. Follow your receiver's instructions for running its calibration routine after connecting the subwoofer.
