How to Recone a Speaker: A Step-by-Step Guide
Reconing a speaker is a process that requires patience, attention to detail, and some technical knowledge. However, with the right guidance, it can be a cost-effective way to revive an old or worn-out speaker and breathe new life into your sound system. In this article, we will walk you through the process of reconing a speaker, step by step.
What is Reconing?
Before we dive into the process, it’s essential to understand what reconing is. Reconing is the process of replacing the worn-out paper cones in a speaker driver with new ones. This is usually done to restore the speaker’s original sound quality, improve efficiency, and increase its overall lifespan. Reconing can be applied to various types of speakers, including woofers, midranges, and tweeters.
Preparation is Key
Before starting the reconing process, make sure you have the following:
- A clean and well-lit workspace
- A speaker driver (woofers, midranges, or tweeters)
- New speaker cones
- A cone- shaping tool
- A sewing kit (for dealing with any tears or holes)
- A wire (for creating a new suspension system)
- A small amount of lubricant (for greasing the voice coil)
- A magnifying glass (for inspecting the driver’s components)
Step 1: Disassemble the Speaker
To begin the reconing process, you need to disassemble the speaker. This is a crucial step, as it allows you to access the various components and prepare the driver for the new cones. The following steps are typical for most speakers:
- Remove the speaker grille
- Take out the screws holding the driver in place
- Carefully lift the driver out of the speaker enclosure
Step 2: Inspect the Driver
Now that the driver is out, inspect it for any damage or wear and tear. Check for any tears, rust, or corrosion on the frame, the screw holes, or the voice coil. Identify any broken or damaged components and make a note to replace them.
Step 3: Remove the Old Cones
Use a cone- shaping tool to carefully remove the old cones from the driver. This may require some force, as they are usually glued in place. Make sure to handle the cones gently to avoid damaging them, as you will need them for future reference.
Step 4: Prepare the New Cones
Take the new cones and place them in a vice, securing them firmly in place. Use a small amount of lubricant to help the cones slide onto the voice coil later. Leave the cones to sit for a few hours to settle and relax the fibers.
Step 5: Assemble the New Cones
Once the new cones have settled, it’s time to assemble them onto the driver. Apply a small amount of grease to the voice coil and carefully slide the cones onto it. Make sure they are seated evenly and securely.
Step 6: Secure the New Cones
Use the cone- shaping tool to secure the new cones in place. Start with the edge of the cone, working your way around and then to the center. Make sure the cone is evenly spaced and not too tight or too loose.
Step 7: Reassemble the Speaker
Carefully lift the driver back into the speaker enclosure. Reattach the screws and make sure they are tightened securely. Reattach the grille and you’re almost done!
Step 8: Test the Speaker
The final step is to test the speaker to make sure it’s working properly. Plug it in, turn it on, and listen to the sound quality. If the speaker is still producing distortion or unusual noises, you may need to make some adjustments or re-map the driver’s frequency response.
Tips and Tricks
Here are a few more tips and tricks to keep in mind when reconing a speaker:
- Work in a well-lit area, as this will make it easier to see any minor tears or imperfections on the cones.
- Use a sewing kit to repair any tears or holes in the cones or the driver.
- Apply a small amount of lubricant to the voice coil and the cones to aid in the assembly process.
- Be patient and take your time. Reconing a speaker is a slow and meticulous process.
- Take notes and keep track of any repairs or adjustments made during the process.
- Test the speaker in various frequencies to ensure that it’s producing a flat and balanced sound.
Conclusion
Reconing a speaker is a complex and detailed process, but with the right guidance and patience, it can be a successful and cost-effective way to revive an old or worn-out speaker. By following these steps, you can breathe new life into your sound system and enjoy a superior listening experience. Remember to take your time, work carefully, and don’t be afraid to ask for help if needed. Happy reconing!
