Setup and Installation
Proper installation is crucial for optimal performance. Consider the following steps:
- Enclosure Selection: The SRX1044V is designed to perform well in both sealed and ported enclosures.
- Sealed Enclosures: Typically provide tighter, more accurate bass response, suitable for musical detail.
- Ported Enclosures: Generally offer louder output and deeper bass extension, often preferred for impact.
- Mounting:
- Ensure the mounting surface is rigid and free from obstructions.
- Use appropriate fasteners to secure the subwoofer firmly to the enclosure.
- Verify that the subwoofer's mounting depth (4.48 inches) and cutout diameter (9.17 inches) are compatible with your chosen enclosure.
- Wiring: Refer to the "Wiring Configurations" section for detailed instructions on connecting the dual voice coils. Ensure all connections are secure and properly insulated.
- Amplifier Matching: Select an amplifier that can deliver the recommended RMS power (300W) at the final impedance load of your subwoofer wiring configuration.
Wiring Configurations (Dual 4-Ohm Voice Coils)
The SRX1044V features dual 4-ohm voice coils, offering flexibility in wiring to achieve different impedance loads for your amplifier. Always ensure your amplifier is stable at the chosen impedance.
1. Parallel Wiring (2-Ohm Load)
Connecting both 4-ohm voice coils in parallel will result in a 2-ohm total impedance. This configuration is common for maximizing amplifier power output, provided the amplifier is 2-ohm stable.
- Connect the positive terminal of Voice Coil 1 to the positive terminal of Voice Coil 2.
- Connect the negative terminal of Voice Coil 1 to the negative terminal of Voice Coil 2.
- Connect the combined positive terminals to the amplifier's positive output.
- Connect the combined negative terminals to the amplifier's negative output.
2. Series Wiring (8-Ohm Load)
Connecting both 4-ohm voice coils in series will result in an 8-ohm total impedance. This configuration is useful for amplifiers that are not 2-ohm stable or when a higher impedance is desired.
- Connect the positive terminal of Voice Coil 1 to the amplifier's positive output.
- Connect the negative terminal of Voice Coil 1 to the positive terminal of Voice Coil 2.
- Connect the negative terminal of Voice Coil 2 to the amplifier's negative output.
Important: Always verify the final impedance with a multimeter before connecting to an amplifier to prevent damage to your equipment.
Operating Guidelines
Break-in Period
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components (spider and surround) to loosen up and reach their optimal performance characteristics.
Power Handling
The SRX1044V has an RMS power rating of 300 Watts and a peak power rating of 600 Watts. It is recommended to match your amplifier's output to the subwoofer's RMS rating for sustained performance and longevity. Overpowering or underpowering the subwoofer can lead to damage.
Setting Amplifier Gains
Properly setting your amplifier's gain is crucial. Do not use the gain control as a volume knob. It should be set to match the output voltage of your head unit. Incorrect gain settings can lead to clipping, which can severely damage the subwoofer.
Maintenance
The Memphis Audio SRX1044V subwoofer requires minimal maintenance:
- Cleaning: Use a soft, dry cloth to gently wipe the cone and surround. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check all wiring connections for tightness and ensure there are no frayed wires or exposed conductors.
- Environment: Ensure the subwoofer is not exposed to direct sunlight for extended periods or extreme temperature fluctuations, which can degrade materials over time.
