How to Recone a Speaker

Reconing a speaker is a process that involves replacing the damaged or worn-out components of a speaker’s cone, voice coil, and spider to restore its functionality and sound quality. Whether you’re an audio enthusiast or a professional sound engineer, learning how to recone a speaker can save you money and extend the life of your speakers. In this comprehensive guide, we will walk you through the steps and techniques involved in reconing a speaker. So let’s dive in and get started!

Section 1: Understanding the Components of a Speaker

Before diving into the reconing process, it’s essential to have a basic understanding of the main components of a speaker. Familiarizing yourself with these components will help you better comprehend the reconing process and enable you to make informed decisions when selecting replacement parts. The key components of a speaker include:

1. Cone: The cone is the diaphragm of the speaker that moves back and forth to produce sound waves. It is typically made of lightweight materials such as paper, plastic, or aluminum.

2. Voice Coil: The voice coil is a coil of wire suspended within the magnetic field of the speaker’s magnet. When an electrical current passes through the coil, it generates a magnetic field that interacts with the permanent magnet, causing the cone to vibrate and produce sound.

3. Spider: The spider, also known as the suspension or damper, is a flexible component that supports the voice coil and allows it to move freely within the magnetic gap.

4. Surround: The surround, also called the suspension, is a flexible ring that connects the outer edge of the cone to the speaker basket, allowing the cone to move while maintaining its position.

5. Magnet: The magnet provides the magnetic field required to interact with the voice coil and produce sound. It is typically a permanent magnet made of materials such as ferrite or neodymium.

Section 2: Assessing Speaker Damage

Before embarking on the reconing process, it is crucial to assess the extent of the speaker damage. This evaluation will help you determine whether reconing is necessary or if other repairs or replacements are more appropriate. Here are some common signs of speaker damage:

1. Torn Cone: Inspect the speaker cone for tears, punctures, or other physical damage. A damaged cone can affect the overall sound quality and performance of the speaker.

2. Burnt Voice Coil: A burnt voice coil can cause distortion, reduced volume, or even complete failure of the speaker. Check for any signs of discoloration or burning on the voice coil.

3. Detached or Damaged Spider: Examine the spider for any detachment, tears, or fraying. A damaged spider can prevent the voice coil from moving freely, leading to distorted or muffled sound.

4. Loose Surround: If the surround is loose or deteriorated, it can affect the speaker’s ability to move air efficiently, resulting in reduced bass response and overall sound quality.

Once you have identified the specific areas of damage, you can proceed with the reconing process.

Section 3: Gathering the Necessary Tools and Materials

To recone a speaker, you will need several tools and materials. Having everything prepared beforehand will make the reconing process smoother and more efficient. Here is a list of essential tools and materials:

1. Replacement Speaker Kit: This kit should include a new cone, voice coil, spider, and surround that are compatible with your speaker model. It’s important to choose high-quality replacement parts to ensure optimal performance.

2. Screwdriver Set: A set of screwdrivers in various sizes will be needed to remove the speaker from its enclosure and disassemble its components.

3. Soldering Iron and Solder: These tools are used to connect the voice coil wires to the speaker terminals. Make sure you have a soldering iron with adjustable temperature settings to avoid damaging the voice coil.

4. Adhesives: You will need specific adhesives to bond the new components together. Speaker repair adhesives such as cyanoacrylate glue (CA glue) and epoxy are commonly used.

5. Heat Gun or Hairdryer: A heat gun or hairdryer is essential for softening adhesives during the reconing process.

6. Multimeter: This tool is used to check the continuity and resistance of the voice coil before and after reconing.

Section 4: Step-by-Step Reconing Process

Now that you have gathered all the necessary tools and materials, let’s walk through the step-by-step process of reconing a speaker:

Step 1: Remove the Speaker
– Use a screwdriver to remove the speaker from its enclosure or cabinet. Take note of the wiring connections to ensure proper reinstallation later.

Step 2: Disassemble the Speaker
– Carefully disassemble the speaker by removing the dust cap, cone, spider, and voice coil. Use a heat gun or hairdryer to soften any adhesives that may be securing these components.

Step 3: Clean and Prepare the Speaker Frame
– Use a clean cloth or brush to remove any dust, debris, or old adhesive from the speaker frame. Make sure the frame is smooth and free of any obstructions that could interfere with the reconing process.

Step 4: Attach the Spider
– Apply a small amount of adhesive to the top of the speaker frame and carefully position the spider on top. Make sure it is centered and aligned correctly. Allow the adhesive to dry according to the manufacturer’s instructions.

Step 5: Install the Voice Coil
– Place the voice coil into position on the spider. Ensure that it is aligned with the spider and held in place securely. Apply adhesive to the spider’s landing area to bond the voice coil properly.

Step 6: Attach the Cone
– Apply a thin, even layer of adhesive to the outer edge of the cone and carefully position it on top of the voice coil. Make sure it is centered and aligned correctly. Apply light pressure to ensure a strong bond.

Step 7: Install the Dust Cap
– Attach the dust cap to the center of the cone using adhesive. The dust cap protects the voice coil and adds structural integrity to the cone.

Step 8: Allow the Adhesive to Cure
– Place the reconed speaker in a clean and dust-free environment, allowing the adhesive to fully cure according to the manufacturer’s instructions. This can take several hours or overnight.

Step 9: Test the Reconed Speaker
– Once the adhesive has cured, reattach the speaker to its enclosure or cabinet. Use a multimeter to test the continuity and resistance of the voice coil. Ensure that all connections are secure and functioning correctly.

Section 5: Post-Reconing Tips and Maintenance

After reconing your speaker, it’s essential to follow these tips and maintenance practices to ensure its longevity and optimal performance:

1. Break-In Period: Newly reconed speakers may require a break-in period to achieve their full potential. Play music or tones at moderate volume for several hours to help the components settle and reach their optimal performance level.

2. Proper Handling: Handle reconed speakers with care to avoid any unnecessary stress or damage to the newly reconed components. Avoid pushing or poking the cone and ensure that the speaker is securely mounted or installed.

3. Regular Inspection: Periodically inspect the reconed speaker for any signs of damage, loose connections, or abnormal behavior. Address any issues promptly to prevent further damage.

4. Cleaning: Keep the speaker and its components clean by gently dusting them with a soft brush or cloth. Avoid using harsh chemicals or abrasive materials that can damage or degrade the speaker’s surfaces.

Reconing a speaker may seem like a daunting task, but with the right tools, materials, and guidance, it can be accomplished successfully. By following the step-by-step process outlined in this guide, you can restore the functionality and sound quality of your speakers. Remember to take your time, be patient, and pay attention to detail during each phase of the reconing process. Happy reconing!
