5. Setup and Installation
5.1 Pre-installation Checks
- Ensure your amplifier is compatible with a 4 Ohm load (or 2 Ohm/8 Ohm depending on wiring configuration).
- Verify that the mounting location and enclosure are suitable for a 12-inch subwoofer.
- Gather all necessary tools and wiring materials.
5.2 Wiring Configurations (Dual 4 Ohm Voice Coils)
The SR-W122D features dual 4 Ohm voice coils, offering flexibility in wiring to achieve different impedance loads for your amplifier.
- Parallel Wiring (2 Ohm Load): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect the combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This configuration presents a 2 Ohm load to the amplifier.
- Series Wiring (8 Ohm Load): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive terminal to the amplifier's positive output and the remaining negative terminal to the amplifier's negative output. This configuration presents an 8 Ohm load to the amplifier.
Always ensure your amplifier is stable at the chosen impedance load. Consult your amplifier's manual for compatibility.
5.3 Enclosure and Mounting
- Install the subwoofer into a suitable enclosure (sealed or ported) designed for a 12-inch driver.
- Ensure the enclosure is robust and free from air leaks.
- Secure the subwoofer to the enclosure using appropriate screws, ensuring a tight seal.
5.4 Connecting to Amplifier
- Connect the subwoofer's wired output (from your chosen impedance configuration) to the amplifier's subwoofer output terminals.
- Ensure correct polarity (+ to + and - to -) to avoid phase issues.
- Double-check all connections before powering on the system.
6. Operating Instructions
6.1 Initial Power-Up and Settings
- Start with the amplifier's gain control set to minimum.
- Turn on your audio system and play music with a good bass range.
- Slowly increase the amplifier's gain until the desired bass level is achieved without distortion.
- Adjust the low-pass filter (LPF) on your amplifier to blend the subwoofer's output with your main speakers (typically between 80Hz and 120Hz).
- Adjust the phase control (if available on your amplifier) to ensure optimal bass response.
6.2 Break-in Period
Allow a break-in period of approximately 10-20 hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components to loosen up, leading to improved performance and longevity.
7. Maintenance
- Cleaning: Use a soft, dry cloth to wipe down the subwoofer cone and surround. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check all wiring connections for tightness and signs of corrosion. Inspect the subwoofer's cone and surround for any tears or damage.
- Storage: If storing the subwoofer for an extended period, ensure it is kept in a cool, dry place, away from direct sunlight and extreme temperatures.
