Setup and Installation

Proper installation is crucial for optimal performance and longevity of your subwoofer. It is recommended that installation be performed by a qualified professional.

Mounting Considerations

• Ensure the mounting surface is rigid and free from vibrations.
• Verify adequate clearance behind the subwoofer for proper excursion and ventilation.
• The subwoofer requires a mounting depth of approximately 6.5 inches.

Wiring

The YSW122 features dual 2-ohm voice coils, offering flexible wiring options to achieve different impedance loads for your amplifier. Common configurations include:

• 1 Ohm Load: Wire voice coils in parallel. This configuration draws maximum power from compatible amplifiers.
• 4 Ohm Load: Wire voice coils in series. This configuration is suitable for amplifiers that are stable at 4 ohms.

Always consult your amplifier's manual to ensure it can safely operate at the chosen impedance. Use high-quality speaker wire of appropriate gauge for your power levels.

Operating Instructions

Once installed, proper operation ensures the best sound quality and extends the life of your subwoofer.

Break-in Period

Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its maximum capabilities. This allows the suspension components (surround and spider) to loosen up and perform optimally.

Amplifier Gain Setting

Set your amplifier's gain control carefully. The gain control is not a volume knob; it matches the output voltage of your head unit to the input sensitivity of the amplifier. Setting it too high can lead to clipping and damage to the subwoofer. It is recommended to use an oscilloscope or a distortion detector for accurate gain setting.

Crossover Settings

Utilize your amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical LPF setting for a subwoofer is between 60 Hz and 100 Hz, depending on your other speakers and personal preference. Avoid sending full-range audio to the subwoofer.

Maintenance

The NVX YSW122 is built for durability, but simple maintenance can help preserve its appearance and performance.

• Cleaning: Use a soft, dry cloth to wipe down the subwoofer cone and surround. Avoid using harsh chemicals or abrasive cleaners.
• Inspection: Periodically inspect the speaker terminals and wiring connections to ensure they are secure and free from corrosion.
• Environment: Protect the subwoofer from extreme temperatures, direct sunlight, and moisture.
