• The 500 Series "e" revision includes a 3-inch voice coil with a 120oz magnet motor, offering a 50% increase in Xmax due to an extra 12mm of top plate and longer coil windings.
• Increased power handling up to 750 Watts RMS for the 512 model.

Setup and Installation

Proper installation is crucial for the performance and longevity of your subwoofer. It is recommended to have the subwoofer installed by a qualified professional.

Enclosure Recommendations:

• For optimal performance, the 512E-D2 is designed for use in a ported enclosure.
• Recommended ported enclosure volume: 1.75 - 2.75 cubic feet.
• Ensure the enclosure is well-constructed and sealed to prevent air leaks.

Wiring and Impedance:

The 512E-D2 features a Dual 2-Ohm voice coil configuration. This allows for flexible wiring options to achieve different final impedances at your amplifier.

• Parallel Wiring: Connect both 2-Ohm voice coils in parallel to achieve a 1-Ohm final impedance. This configuration is suitable for amplifiers stable at 1-Ohm.
• Series Wiring: Connect both 2-Ohm voice coils in series to achieve a 4-Ohm final impedance. This configuration is suitable for amplifiers stable at 4-Ohm.

Always match the subwoofer's final impedance to the amplifier's stable impedance rating. Incorrect impedance matching can lead to amplifier overheating and damage.

Mounting:

• Ensure the mounting surface is sturdy and free from obstructions.
• The mounting diameter required is 11.02 inches, with a mounting depth of 6.5 inches.
• Use appropriate fasteners to secure the subwoofer firmly in place.

Operating Guidelines

Once installed, follow these guidelines for optimal operation:

• Break-in Period: Allow a break-in period of approximately 20-30 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components to loosen and perform optimally.
• Gain Setting: Properly set the gain on your amplifier to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to clipping and damage to the subwoofer.
• Crossover Settings: Use a low-pass filter (LPF) on your amplifier or head unit to send only bass frequencies to the subwoofer. A typical LPF setting for a 12-inch subwoofer is between 60Hz and 80Hz.
• Subsonic Filter: Utilize a subsonic filter (HPF) to protect the subwoofer from playing frequencies below its resonant frequency (Fs). For the 512E-D2 (Fs: 33 Hz), a subsonic filter set around 25-30Hz is recommended.
• Power Handling: The subwoofer has a continuous RMS power handling of 700 Watts and a peak power handling of 2100 Watts. Ensure your amplifier's output matches these ratings to prevent underpowering or overpowering.

Maintenance

The DD Audio 512E-D2 subwoofer requires minimal maintenance. Follow these simple steps to ensure its longevity:

• Keep the subwoofer clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the subwoofer to direct sunlight or extreme temperatures for extended periods.
• Regularly check all wiring connections to ensure they are secure and free from corrosion.
• Do not apply any liquids or harsh chemicals directly to the cone or surround.
