Frequently Asked Questions - Apocalypse DPW-1540 Deaf Bonce

How do I properly connect the subwoofer?

Refer to the wiring diagrams in the manual. The subwoofer has a 4 Ohm voice coil. You can wire multiple subwoofers in series or parallel to achieve the desired total impedance, but never go below the amplifier's minimum load.

What is the recommended enclosure volume for the DPW-1540?

For a bass reflex enclosure, the recommended volume is 70 liters (2.5 ft³). The port area should be 450 cm² (70 in²) and the port length 25 cm (9.8 in) with a tuning frequency of 65 Hz.

What is the power handling of this subwoofer?

The subwoofer has a continuous power handling of 1000 W RMS and a maximum power of 2000 W. It is recommended to use an amplifier with nominal power below these values.

How should I break in the subwoofer?

Play musical material at medium power for about 40 hours to warm up the moving parts. This helps prevent damage and improves long-term performance.

What are the recommended amplifier settings?

Set the head unit volume to no more than 80%. Set amplifier sensitivity to 50%, subsonic filter to 5 Hz below the port tuning (e.g., 60 Hz if tuning is 65 Hz), low-pass filter (LPF) to 80-100 Hz, and bassboost to 0.

How can I avoid damaging the subwoofer?

Avoid overdriving the subwoofer. If you smell a burning odor or hear distortion, reduce the volume immediately. Use an enclosure that meets the recommended specifications and ensure proper amplifier settings.

What is the impedance of the DPW-1540?

The subwoofer has a nominal impedance of 4 Ohm and a DC resistance (Re) of 3.2 Ohm.

What materials are used in the construction?

The subwoofer features a cloth surround, pressed paper cone, aluminum frame, and a ferrite magnet. The voice coil wire is CCAW (Copper-Clad Aluminum Wire).

What is included in the box?

The package includes: 1 subwoofer, 1 owner's manual, and 1 warranty card.

How should I dispose of this subwoofer?

Do not dispose of it with household waste. Take it to a designated recycling center for electrical and electronic equipment. Contact your local municipal office for the nearest drop-off point.

1. INTRODUCTION

Thank you for purchasing this Deaf Bonce product! Our company is committed to the creation of extremely loud sound systems with no loss of quality.

To ensure proper use, please carefully read through this manual before using this product. It is especially important that you read and observe caution's in this manual. Please keep the manual in a safe and accessible place for future reference.

2. SAFETY INSTRUCTIONS

1. Fasten the subwoofer properly when installing it in the vehicle. If the component is disconnected during driving, it may cause serious damage to the passengers of the vehicle or another vehicle.
2. Before installing the components, if possible store the product in its original package to avoid accidental damage to the product.
3. Be careful when installing and dismantling the subwoofer! Do not let the subwoofer drop to avoid damage of its moving parts.
4. When working with tools follow safety rules.
5. Before the installation switch off the head unit and all other audio devices to avoid their damage.
6. Make sure that the location of the subwoofer does not hinder the proper operation of mechanical and electrical devices of the vehicle.
7. Do not install components in places exposed to water, excessive humidity, high or low temperature, dust or dirt. ATTENTION!!! The product may be operated at +5 °C (41F) to +40 °C (104F). In case of moisture condensation, let the product to dry.
8. When performing plumbing, drilling or cutting works with the car, make sure that there is no wiring, brake lines, fuel pipe or other structural elements under the place of work. Follow the safety rules! Use protective glasses and gloves.
9. When stretching back the speaker cables make sure that they are not in contact with sharp edges or moving mechanical devices. Make sure that they are firmly fixed and protected over the entire length.
10. The diameter of the speaker cables must be selected in accordance with the length and applied power.
11. Never stretch the cables outside of the car and near the moving parts of the car. This can lead to destruction of the insulating layer, short circuit and fire.
12. To protect the cables use rubber gaskets if the wire passes through a hole in the plate, or other similar materials if it lies close to the parts exposed to heat.

CAUTION!!! High sound pressure can damage your health! Please use the common sense when controlling volume!

5. HOW TO USE

The correct choice of the amplifier, its settings and enclosure design prolongs the lifetime of your subwoofer. You should select an amplifier with a nominal power below the nominal power of the subwoofer. Proper coordination of the head unit (HU) with the amplifier will provide a clean, undistorted signal fed to the subwoofer, which prevents overheating and voice coil damage. Like any other speaker the subwoofer has moving and stationary parts. We strongly recommend that the moving parts of the subwoofer should be warmed up at the beginning of operation. Be extra careful when warming up the parts. Warm up the subwoofer using musical material for 40 hours at medium power. If, during operation at maximum volume you feel strange smell, you should lower the volume of the subwoofer and let the device to cool down at a low volume.

Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier sensitivity should be set to 50%, subsonic filter frequency should be set to 5 Hz below the port settings. For example, if you configure the port at 30 Hz, Subsonic should be set to 25 Hz. The low pass filter LPF (the filter that cuts all frequencies above those set for the filter) should be set to 80-100 Hz, bassboost should be set to 0.
