One of the most crucial parts of any automotive speaker system is the dust cap, or “dust dome,” which acts as a gentle curving cap that covers the diaphragm’s central hole in either a concave or convex position. The inner workings of the vehicle are protected from small particles and other pollutants (such as the pole pieces and the voice coil).
Additionally, dust covers can aid in the structural integrity of the voice coil assembly and the cone. Depending on the loudspeaker design, dust caps can either radiate or restrict high-frequency radiation as part of the driver’s acoustic design.
If you have some basic tools, you can make your own speaker cap.
Needed Materials
- A notebook paper
- Marker
- Rubber stamp with any ink
- And cutter [scissors or razor blade]
- Measuring tape
- Ruler
- pencil
How to Make Your Own Speaker Dust Cap: Steps to Take
Step 1: Doodle two circles
First, measure the speaker cap. Then, draw two circles on a piece of paper that are big enough to fit the diaphragm you just measured.
Step 2: Cut a hole between the two circles.
Use the necessary tools [pencil and ruler] to make a cut between the two circles you made. Make sure the cut divides the circles into four parts.
Step 3: Cut a circle out of the paper
Now you need to cut off the circles you drew in the last step and the line you drew to divide them. The line you drew to divide them is an important part of making the dust cap.
Step 4: Add ink to the stamp pad.
After putting ink on the stamp pad, cover the two pieces of paper with it. Ink can’t cover more than a quarter of the paper, because that could make it hard to put them in. If you need to, add more ink to make sure it’s covered evenly, then let it dry.
Step 5: Take off the old diaphragm.
Put your speaker in the right place and take out the screw or whatever is holding the diaphragm or ring in place. Save anything you take out for when you’ll need it again.
Step 6: Put the dust cap on.
The ink should have dried on the paper by now. Get it and put it in the speaker. Then, make sure everything is just right.
Step 7: Put the diaphragm back in.
This is the last step. Find the screw you saved in step 5 and use it to replace your speaker’s diaphragm. Also, you might need to use the right glue to put the speaker cap back on. During testing, make sure the diaphragm is well attached so the speaker works well.

Method of a Piece of Cloth
For this method to work, you will need a piece of fabric that is much bigger than the speaker. Measure the speaker and cut out the shape of the dust cap. Then sew the edges together. To avoid sound leakage or tears, it is best to choose a fabric that is fairly thick.
Method for a Piece of Plastic
This is the best way to make a dust cover that is both strong and water-resistant.

How to Fix a Speaker Dust Cap With a Dent
If the dust cap on your speaker is made of something like paper, do the following to replace or fix it.
- Remove the brush from the vacuum cleaner. If it has an aluminum telescope, take it off. If the bag is full of dust, throw it away ahead of time. Hopefully, your vacuum is strong enough.
- Put your speaker on a table with good lighting so you can get to it quickly and easily.
- Turn on the vacuum and move the hose slowly toward the speaker. Don’t touch the dust cap unless you have to, at least until it takes its first shape.
- Now, you have to keep going. Repeat step 3 as many times as you need to. Get as close to the hump as you can without touching the dust cap. Repeat for at least one to two minutes, and the lump will slowly disappear until the skin is almost perfect.
- Use your fingers very carefully to figure out how the process works. You can’t do it perfectly, but if you use this plan, you’ll get pretty close.
If you’re not sure what you’re doing, you shouldn’t use needles, tapes, pens, sticks, or other similar items.

- Prick the side of the speaker cap that has been bent.
- Make a small bend in your pin and gently lift the dented cap with the part of the pin that is inside the cap.
- Do this in a circle until the shape of your speaker cap is close to how it was before.
