Configuracions de cablejat:
The Rockville W12K9D2 features Dual Voice Coils (DVC) with a 2-ohm impedance per coil, offering various wiring options to match your amplifier's stable impedance. Below are common wiring configurations for single and dual subwoofer setups.
Wiring for One DVC 2-Ohm Subwoofer:
Video: Detailed instructions on wiring a single Dual Voice Coil (DVC) 2-ohm subwoofer. This video demonstrates how to achieve different impedance loads (1-ohm or 4-ohm) from a single DVC 2-ohm subwoofer by connecting the voice coils in parallel or series, respectively. It also provides recommendations for amplifier matching.
Wiring for Two DVC 2-Ohm Subwoofers:
Video: Comprehensive guide for wiring two Dual Voice Coil (DVC) 2-ohm subwoofers. This video illustrates various series and parallel wiring configurations to achieve desired impedance loads (e.g., 0.5-ohm, 2-ohm, 8-ohm) when using two DVC 2-ohm subwoofers, along with amplifier compatibility advice.
Instruccions de funcionament
Once properly installed and wired, operate your subwoofer system responsibly to ensure longevity and optimal sound quality. Avoid excessive volume levels that cause audible distortion or clipping from your amplifier, as this can damage the subwoofer.
- Període d'entrada: Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at maximum output. This allows the suspension components to loosen up and perform optimally.
- Configuració de guany: Estableix el teu ampguany del lificador correctament per coincidir amb el volum de sortidatage of your head unit. Incorrect gain settings can lead to distortion and potential damage.
- Configuració de crossover: Utilitza el teu amplifier's low-pass filter (LPF) to send only low-frequency signals to the subwoofer. A typical starting point for the LPF is around 80-100 Hz.
- Filtre subsònic: Si el teu amplifier has a subsonic filter, set it slightly below your enclosure's tuning frequency to protect the subwoofer from playing frequencies too low for its design.
Manteniment
The Rockville W12K9D2 subwoofer requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Neteja: Feu servir un drap suau i sec per netejar el con i l'entorn del subwoofer. Eviteu utilitzar productes químics agressius o netejadors abrasius.
- Inspecció: Periodically inspect the wiring connections to ensure they are secure and free from corrosion. Check the cone and surround for any signs of damage or wear.
- Medi ambient: Ensure the subwoofer is installed in a dry environment, protected from extreme temperatures and direct sunlight.
Resolució de problemes
If you experience issues with your Rockville W12K9D2 subwoofer, refer to the following common troubleshooting steps:
- Sense so:
- Check all wiring connections (power, ground, remote, speaker wires) to ensure they are secure and correctly connected.
- Verifiqueu el amplifier is powered on (power indicator light should be illuminated).
- Comproveu el amplifier's fuses and the main fuse at the battery.
- Ensure the head unit is sending an audio signal to the amplifier (check RCA connections).
- So distorsionat:
- Reduir el ampajust de guany del lificador.
- Check for clipping on the amplifier (some amps have a clipping indicator).
- Ensure the subwoofer is not over-excursing (moving too far in and out).
- Verify crossover settings are appropriate for the subwoofer and enclosure.
- Greus febles:
- Augmentar el amplifier's gain setting gradually.
- Check the phase setting on your amplifier or head unit (if available).
- Ensure the subwoofer is wired to the correct impedance for your ampmés viu.
- Verify the enclosure is sealed properly (if applicable) and free from air leaks.
