Types of Double Magnets Subwoofer

A double magnets subwoofer is a loudspeaker that reproduces low-frequency sounds. It is also known as a bass speaker or bass driver. There are two types of double magnets subwoofers:

• Sealed subwoofer

  A sealed double magnet subwoofer has an airtight enclosure. The enclosure is sealed to prevent airflow into and out of the subwoofer driver. When the subwoofer cone moves forward and backward, the air pressure inside the enclosure changes. The change in air pressure affects the cone's ability to reproduce sound accurately.

  Sealed subwoofers produce tight and accurate bass. They have a smooth frequency response and low distortion levels. However, they are less efficient and require more power to produce loud bass. They also have a limited low-frequency response compared to other types of subwoofers.

• Ported subwoofer

  Ported subwoofers have an enclosure with a vent or port. The port allows airflow in and out of the enclosure. When the subwoofer cone moves, the air pressure changes, causing the port to open and close. The airflow through the port enhances the cone's movement and amplifies the sound output.

  Ported subwoofers are more efficient than sealed subwoofers. They require less power to produce loud bass. They also have a better low-frequency response and can reach deeper bass notes. However, ported subwoofers have higher distortion levels and an uneven frequency response. They also produce boomy bass, which is unsuitable for all music genres.

Specification & Maintenance of Double Magnets Subwoofer

The specification of a double magnetic subwoofer varies depending on its type and the manufacturer. Here are some common specifications to consider:

• Power Handling

  Power handling refers to the RMS (root mean square) power and peak power ratings of a double magnet subwoofer. Peak power is the maximum power the sub can handle in a short burst without damaging it. RMS power is the consistent power a subwoofer can handle over a long period.

• Frequency Response

  Frequency response is the range of frequencies the double magnet subwoofer can reproduce. It is measured in Hertz (Hz). A subwoofer with a low frequency response can produce deeper bass sounds than a sub with a higher frequency response.

• Impedance

  Impedance is a specification that indicates how much resistance the subwoofer has to the electrical current coming from the amplifier. It is measured in ohms (Ω). Common impedance ratings for subwoofers are 2 ohms, 4 ohms, and 1 ohm. Double magnet subwoofers with lower impedance ratings can draw more power from the amplifier than those with higher ratings.

• Size

  A double magnet subwoofer comes in different sizes that range from 8 to 18 inches. The size of the subwoofer determines the depth and loudness of the bass sound it produces. Larger subwoofers produce deeper bass sounds.

• Voice Coils

  A double magnet subwoofer has one or more voice coils that are wrapped around a magnetic core and are responsible for converting electrical signals into sound waves. Voice coils are either single or double and can vary in diameter.

• Enclosure Type

  Subwoofers are designed to be installed in a sealed enclosure, a ported enclosure, or a bandpass enclosure. The different types of enclosures affect the sound quality and performance of the subwoofer.

To keep a double magnet subwoofer in good working condition and ensure it lasts longer, it is important to maintain it. Here are some tips on how to maintain a double magnet subwoofer:

• Regularly clean the subwoofer to prevent dust and dirt from accumulating.
• Inspect the subwoofer frequently for signs of damage or wear and tear.
• Check the wiring connections of the subwoofer to ensure they are secure and not loose.
• Ensure the double magnet subwoofer is not overpowered by the amplifier.
• It is important to use the subwoofer within its specified limits.
• A double magnet subwoofer should be stored in a dry and cool place away from direct sunlight.
• Double magnet subwoofer should not be exposed to extreme temperatures or humidity.
• Subwoofer should be broken in properly before being used at high volume levels.
• Use a low-pass filter to prevent the subwoofer from trying to play higher frequencies.

How to Choose Double Magnet Subwoofer

There are several factors to consider when choosing a double magnet subwoofer, and they include the following:

• Space Requirements

  For a smaller car, a compact subwoofer is the best option, as it will not only fit into the car but will also not be overwhelming.

• Power Handling Capacity

  The subwoofer should be compatible with the car's sound system or amplifier. If the sound system has a high power rating, it requires a subwoofer with high power handling capacity.

• Sound Quality vs. Sound Pressure

  If one is an audiophile and loves listening to music with high quality, then the focus should be on sound quality. In contrast, for a person that enjoy loud music, the double magnets subwoofer that prioritize sound pressure should be chosen.

• Budget

  Double magnet subwoofers are available in a variety of prices, so it is advisable to set a budget beforehand. Keep in mind that an expensive subwoofer can give more value in terms of quality and durability.

How to DIY and Replace Double Magnets Subwoofer

Setting up a double subwoofer in a car can be a DIY-friendly project. Below are the steps and requirements that will guide the installation process:

Before starting, gather the necessary tools for the job:

• Carpenter's Glue
• Screws
• Vaseline
• Wire Cutters
• Electrical Tape
• Wrench
• Screwdriver
• Drill
• Jigsaw
• Multimeter
• Socket Extension
• Gluing Clamp

After getting the tools, follow the steps below:

• 1. Choose the Right Subwoofer: Select a subwoofer that fits within the space constraints of the vehicle and meets sound quality requirements.
• 2. Prepare the Vehicle: Clear out the trunk or area where the subwoofer will be installed and ensure that the space is clean and free of debris.
• 3. Create a Subwoofer Enclosure: A subwoofer enclosure is necessary for the double 12-inch subwoofer because it enhances sound quality and safeguards it. Constructing a subwoofer enclosure requires measuring the subwoofer's internal dimensions and cutting the MDF boards. Once the boards have been cut, assemble the enclosure using glue and screws. Finally, seal all the joints with caulk to make the enclosure airtight.
• 4. Install the Subwoofers: Make holes in the enclosure's top surface that are big enough for the subwoofers' mounting screws. Install the subwoofers into the enclosure, making sure they are flush with the surface.
• 5. Wire the Subwoofers: Use the wire cutters to cut two lengths of speaker wire that are long enough to connect each subwoofer to the amplifier. Strip one end of each wire to reveal the bare conductors, then connect them to the subwoofer terminals using electrical tape to secure them. Connect the other ends of the wires to the amplifier terminals, following the wiring diagram provided by the manufacturer.
• 6. Secure the Enclosure: Use a socket extension and a wrench to secure the enclosure. Make sure the enclosure is securely fastened and does not move around while driving.
• 7. Test the System: Use a multimeter to ensure the wiring is correct and the impedance matches the amplifier's specifications. Turn on the car and test the sound system to ensure the subwoofers function properly. Adjust the gain and crossover settings on the amplifier to achieve the desired sound quality.
