Frequently Asked Questions - Machete MFT-25 Deaf Bonce

How do I wire the Machete MFT-25 speaker?

Connect the positive terminal of the speaker to the positive output of your amplifier, and the negative to the negative. Ensure the amplifier is turned off during connection.

What is the recommended amplifier power for this speaker?

An amplifier delivering between 300W and 600W RMS at 4 ohms is recommended to match the speaker's power handling.

Can I use the MFT-25 in a home audio system?

It is designed for car audio, but can be used at home with a suitable power supply and amplifier, though enclosure requirements may differ.

What type of enclosure is best for this subwoofer?

A sealed or ported enclosure works well. For optimal performance, consult the manual for recommended box volume (typically 1.5-2.5 cubic feet).

How do I clean the speaker?

Wipe the cone and surround with a soft, dry cloth. Do not use any liquids or cleaners.

Is the MFT-25 compatible with a 2-ohm amplifier?

No, the speaker has a 4-ohm impedance. Connecting it to a 2-ohm output may damage the amplifier or speaker.

What is the diameter of the speaker?

The MFT-25 has a nominal diameter of 25 cm (10 inches).

Does the speaker come with mounting hardware?

Yes, it includes screws and brackets for standard installation. Check the manual for detailed mounting instructions.

How do I break in the new speaker?

Play music at moderate volume for about 10-20 hours to allow the suspension to loosen. Avoid full power during break-in.

What should I do if the speaker produces distortion?

Check the amplifier settings, ensure the gain is not too high, and verify that the enclosure is properly sealed. Distortion often indicates overdriving or a mismatch.

GLOBAL SPONSOR

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 speakers 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 speaker! Do not let the speaker 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 speaker 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!

Selection of the diameter of speaker cables

Use the table below to select the desired diameter based on the length and the power consumption.

4. FILTERING, RECOMMENDED AMPLIFIER SETTINGS

The correct choice of amplifier, its settings, filtering and enclosure largely influence on the lifespan of your audio system. You should select an amplifier with a nominal power, not exceeding the nominal power of the speakers. Proper coordination of the head unit (HU) with the amplifier will allow to get clean, undistorted signal applied to the component to prevent overheating and voice coil damage. Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier sensitivity should be set to 50%.

The recommended filter settings:

The high pass filter HPF (the filter that cuts all frequencies below those set for the filter) should be set to 8 kHz (12 dB/Oct)

Recommended amplifiers: AAB-500.4D, AAB-600.2D, AAP-500.2D, AAP-800.2D, AAP-400.4D.
