Frequently Asked Questions - Machete M15 v2 D2/D4 Deaf Bonce

What is the difference between D2 and D4 models?

The D2 model has dual 2+2 Ohm voice coils, while the D4 model has dual 4+4 Ohm voice coils. This affects the total impedance when wiring in series or parallel, allowing flexibility to match amplifier loads.

What is the recommended enclosure for the M15 v2?

The recommended enclosure is a bass reflex box with an internal volume of 90 liters (3.1 ft³), port area of 200 cm² (30 in²), port length of 40 cm (15.7 in), and tuning frequency of 35 Hz.

How do I wire the subwoofer for a 2 Ohm load?

For a 2 Ohm load, use the D2 version and connect the voice coils in parallel (each coil 2 Ohm, total 1 Ohm). Alternatively, use the D4 version and connect voice coils in series (each coil 4 Ohm, total 8 Ohm) or parallel (total 2 Ohm). Refer to wiring diagrams for exact configurations.

What is the RMS and peak power handling?

The RMS power handling is 500 watts, and the maximum (peak) power handling is 1000 watts.

How do I properly break in the subwoofer?

Play musical material at medium power for approximately 40 hours. During break-in, avoid maximum volume. If you notice a strange smell, reduce volume and allow the subwoofer to cool at low volume.

What amplifier settings are recommended?

Set head unit volume to no more than 80%. Set amplifier sensitivity to 50%. Set subsonic filter 5 Hz below port tuning. Set low-pass filter (LPF) to 63-80 Hz. Set bass boost to 0.

Can I use a sealed enclosure?

The manual only provides parameters for a bass reflex enclosure. For a sealed box, you would need to calculate based on Thiele-Small parameters. However, the recommended design is ported for optimal performance.

What is the voice coil size?

The voice coil size is 2.5 inches, wound with copper wire.

How do I connect the subwoofer to an amplifier?

Connect both voice coils using either series or parallel wiring, ensuring the total impedance matches your amplifier's stable load. Use appropriate gauge speaker wire (e.g., 10 AWG for long runs). See wiring diagrams in the manual.

What is the warranty coverage?

The subwoofer is warranted against defects in materials and workmanship under normal use. Defective units will be repaired or replaced at the manufacturer's discretion. Warranty is valid with the original receipt and warranty card. Transportation damage is not covered.

1. INTRODUCTION

EN

Thank you for purchasing the Deaf Bonce product of Machete series! Our company is committed to the creation of extremely high-profile 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 to +40 °C. 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!

3. WIRING DIAGRAMS

Attention! You need to connect both voice coils of the subwoofer.

Do not expose your amplifier to loads below the value predetermined by the manufacturer.

Various examples of connection types are given at the pages below. Use these examples to determine the required load impedance of your connection.

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 (Subsonic) 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 63-80 Hz, bassboost should be set to 0.
