How to fix a blown subwoofer? Many factors might cause your subwoofer to fail. Underpowering, overwhelming, and providing the sub with far too many speech signals are the most prevalent culprits. When a sub blows, it stops working correctly. And the majority of individuals believe that replacing or updating to a new model is the only choice. However, a blown submarine does not indicate the end of its existence. You can attempt to mend it yourself and give it fresh life. As a result, you will save a large amount of money that you can put towards other requirements. Let’s follow us to find out how to fix a blown subwoofer right now!
Is it true that your subwoofer has blown?
Until you can even consider repairing a subwoofer, you must first determine whether it has been blown. You may accomplish this by just turning on the sub and playing any form of sound through it. Listen carefully…if you detect a hissing noise, that means the woofer is completely blown. If the sub delivers normal sound at limited amounts but becomes distorted when the volume is increased, it may be partially blown. A subwoofer that does not immediately output sound indicates that it is damaged!
A voltmeter may also be used to verify if your subwoofer is damaged. Turn down your sub then set the meter to read ohms before placing it on the sub’s terminals. If it shows 0, it indicates that your woofer has blown. If it displays an infinite reading, the voice coils have been damaged.
How to fix a blown subwoofer
Step 1: Take the speaker out of its casing
You’ll need a screwdriver for this step to assist you to remove the fastening screws that are keeping the speakers in place. While you’re at it, remove all of the associated wires (you’ll like to check which wire comes were for simple reassembly once you’ve repaired the sub). Wrong cable positioning results in choppy audio).
Step 2: Take off the speaker surround
With the speaker totally disengaged from the enclosures and the wires separated, it’s time to remove the speaker frame’s surrounds. To readily remove the surrounding material, use a sharp tool such as a tester blade or putty knife. Remove all of the surround and adhesive from the loudspeaker frame. When eliminating the surrounding material, use extreme caution since the frame corners can easily be damaged.
Step 3: Take out the voice coil and speaker cone.
Pry out the loudspeaker cone and voice coil of your woofer using the sharp item you used during the previous step. Cut the terminal wires of the voice coil using a sharp knife to make it easier to remove the old cones, coil, and spider.
Step 4: Insert a fresh coil.
Prepare the fresh coil that will replace the old one. However, before installing the replacement coil, remove any dust or debris that has been lodged in the speech coil gap. Place the new coils in the gap and a new spider around it. Apply enough adhesive to the cone, then gently fit it into the middle of our new sound coil. Allow up to 24 hours for it to thoroughly dry.
Step 5: Replace the speaker surround.
After you’ve installed the new coil, you’ll need to replace the speaker’s surround. Simply put glue around the borders of the surround (where it will come into contact with the loudspeaker frame) to accomplish this. Then, wrap the surround around the loudspeaker frame and cone. Again, let the surround dry for up to 24 hours.
Step 6: Complete the reassembly procedure
Remember how you separated the coil terminals in step 3? Now is the time to replace them! Simply connect the new coil’s terminal wires to the old terminals and secure them using a soldering iron.
TIP: If your replacement cone does not arrive with pre-attached wires, consider connecting the terminal wires with short wires and then drilling small holes in the new cone. Insert the wires into the holes and solder them to the coil with a soldering iron.
Finally, return the speaker to its enclosure, rejoin the wires you detached in step 1, and replace all of the mounting screws. And you’re finished! Return your subwoofer to its original place, such as beneath the seat for an under-seat woofer or behind the backrest for a free air subwoofer, and continue enjoying the great low-frequency bass audio experience.
If your subwoofer has failed, don’t throw it in the trash or replace it with a new one. Instead, try giving it new life by repairing it using the simple steps indicated above. By fixing your blown subs on your own, you will not only save money, but you will also learn something new.
