How To Test If A Tweeter Is Blown

Tweeters, like speakers, can be blown and produce a harsh sound. If there is only one speaker, it is most usually a negative situation. If you’re using it active, it could be a bad channel in the amplifier or a faulty crossover.

How do I know if my tweeter is blown?

Basically, turn down the level on that tone and place your head holes exactly next to the tweeter. It’s blown if there’s no sound coming from it. If it makes a noise, it could be partially broken or functional. You’re fine if it’s loud and clear, and it sounds like your other speakers.

Can a tweeter is blown?

Perhaps you’ve had your eye on a fantastic deal on a second speaker, or you simply want to know if your current set of speakers sound as wonderful as they did when you initially acquired them. Many audiophiles and music fans have wondered for years whether speakers deteriorate or become bad.

Because I am one of such folks, I decided to conduct some study and provide a definitive solution to this topic. So here’s what I discovered.

Do speakers degrade over time? Yes, in a nutshell. Speakers do break down after a long period of use. Over time, speaker parts such as the surround, cone, crossover capacitor, and ferrofluid in some tweeters deteriorate, lowering the overall sound quality of the speakers.

Some parts of the speaker are more susceptible to wear and tear than others. When these components fail, the overall sound quality of the speakers suffers. So, in the next section, we’ll look at the components of a speaker that deteriorate over time, as well as the elements that lead to a speaker’s degeneration.

We’ll discuss where to get replacement parts for worn-out speaker parts later in the text. I’ll also give you advice on how to care for your speakers so you may enjoy them for years to come. Let’s get started.

What does a bad tweeter sound like?

Are your car speakers blaring? Is the sound not as crisp as it used to be? Your automobile stereo may have a blown speaker or another problem.

Unfortunately, blown speakers are more prevalent than we’d like, particularly in stereos that have been subjected to a lot of bass-heavy music over time. Another typical cause of damage and deterioration is incorrectly mounted speakers, most often with incompatible components.

Thankfully, determining whether or not you have a blown speaker, as well as diagnosing other faults with your car entertainment system, is simple.

We’ve put together a list of car stereo troubleshooting tips to assist you bring your sound system back to the crystal-clear quality you expect.

Diagnosing the Problem: What to Check and Listen For

Listening to what’s coming out of the speakers should be your first move if your car radio isn’t sounding as well as it used to.

Turn on your stereo without starting the engine when sitting in your parked automobile. Keep the engine turned off if you want to avoid making too much noise.

Over your stereo, play a tune you’re familiar with. You’ll want something with a wide variety of sound to help you figure out how your speakers are reacting.

Give it a listen and let us know what you think. Turn increase the volume and listen again with a neutral bass and treble setting.

Keep an ear (and an eye) out for the following issues:

Distortion at Medium Volumes

Distortion, which sounds hissing or blurry, is a common indicator of partially blown speakers. When you raise up the level on your speakers, listen for this fuzzy sound and note if it gets worse as you increase the volume.

A broken voice coil is usually the source of fuzziness, muted sound, and cracking.

No Vibration

Speakers produce sound by vibrating. If you touch your speakers and don’t feel any vibrations, the cone of the speaker may not be receiving power. A wiring problem or a defective component in the automobile stereo system could cause power troubles.

Lack of Range

Your car audio speakers are likely partially blown if you notice a lack of high, medium, and/or bass frequencies in the sound. Listening for lack of range is only possible if you know the song by heart, therefore make sure to check your favorite songs for this problem.

Rattling and Popping Sounds

Your speakers are likely blown if the only sound coming from your woofers is a rattling sound. Popping is another sound to keep an ear out for. Your tweeters are most likely damaged if you hear popping sounds emanating from your speakers.

Car Radio Isn’t Working

If you can’t get your car stereo to switch on at all, or if the display and sound won’t turn on, there’s probably a problem with the power, wiring, fuse, ground connection, or a loose connector at the rear of the head unit.

Testing Connections

Remove the speaker wires from the amp and connect them to a 9-volt battery to test the connection to the speakers. Remove the speaker cover so you can inspect the speaker and determine if the cone is functioning correctly while testing it. If the cone works, the issue is with the connection rather than the speaker.

Infinite Impedance

Electrical response testing is a simple approach to assess a speaker’s performance. You can use a multimeter tester to see if the cone or voice coil is damaged.

Set the meter to ohms, switch off the speaker, and connect the multimeter’s lead to the speaker terminals. A value of 1.0 ohms on a multimeter indicates that the speaker is not blown, whereas a reading of infinite ohms indicates that it is. The impedance of a completely blown speaker will be limitless.

Testing Car Stereo Components

When diagnosing a broken car stereo system, you should also test the amplifier, as it is the source of power for your speakers. The sound of your speakers will be distorted by a broken amp with a faulty fuse or capacitor.

Grab your multimeter reader and open the fuse box on the amp to test it. Connect the multimeter’s red wire to a pole on the fuse. Connect the black wire to a different pole. If you hear a beeping sound after doing this, the fuse is most likely in good condition, but the capacitor is most likely faulty. If no beep is heard, the fuse has blown and needs to be replaced.

Repairing Damage

Remove the cover and inspect for tears, cracks, splits, and holes to see if your speaker has been damaged. The majority of the damage is usually visible on the speaker’s cone. You can also clean out dust and grime by lightly running your fingertips over the speaker to feel for scrapes.

Repairing Minor Damage

A speaker sealer can be used to fix minor holes and tears in your speakers. However, keep in mind that while this will improve the sound quality of the speaker, it will not restore it to its former state.

You’ll need to replace or have your partially or severely blown speakers professionally repaired if you want them to sound like new again.

When Should You Take Your Car Stereo Into the Shop?

This is a simple task. Bring your stereo to a car audio specialist if your speakers are broken and want to be restored to their former splendor. Damaged speakers can be repaired and reinforced by car audio experts, extending their lifespan.

Speakers and automotive radio systems, however, deteriorate over time. However, if you know what to look for (and listen for), you can determine the best course of action for fixing your stereo and making it sound as good as new.

How do you test a speaker to see if it is blown?

It’s a pain, but if you blow a speaker in your amplifier, here’s what you should do.

“Blown speakers” are fairly prevalent in the home and automobile audio worlds. Many people use the term in a non-technical, non-generic sense to describe speakers that aren’t working properly or at all. Mostly, it’s an unwelcome annoyance.

Blowing speakers in a guitar amp (or bass amp, or PA system) is significantly more than a nuisance for musicians, especially working musicians. They can be a serious issue that puts a gig or a session at risk. Fortunately, it occurs significantly less frequently in music equipment than in household and vehicle audio, but it exists, and it presents numerous questions: What does it mean to have a “blown speaker”? What causes a speaker to blow? What should you do if your speaker has blown?

A “blown speaker” is one that is not functioning properly or at all. It’s an umbrella term that covers a variety of issues that might cause a speaker to sound poor or fall silent, but suffice it to say that a blown speaker produces either bad or no sound.

Oh, you’ll figure it out. An unpleasant buzzing or scratching sound, by itself or roughly at the pitch of the note the speaker is attempting to reproduce, is the most common aural symptom of a blown speaker. It’s also possible that there will be no sound at all.

It’s worth mentioning that speakers, when correctly matched, are built to endure whatever their amps can throw at them at extremely high levels and for far longer periods of time than is likely to be experienced in regular use. To maintain this level of quality and compatibility, amp makers employ stringent testing procedures, making blown instrument amp speakers an extremely unlikely occurrence. Nonetheless, it is in the nature of any technology to have issues from time to time, and speakers do blow occasionally despite the amplification industry’s best attempts to prevent it. It’s unlikely, but not unthinkable.

Repair or, more likely, replacement is the best option. Individually sold component loudspeakers, such as those by JBL and Electro-Voice, can frequently be repaired and re-coned (re-coning a speaker means not just replacing the speaker cone, but replacing all the moving parts that constitute the speaker cone assembly; this includes the voice coil).

When calculating the expense of repairing a blown speaker, you may find that it is more cost effective to simply replace it. In that case, click here to read more about Fender speakers.

How can you tell if a speaker is blown out?

If you play a receiver at a volume that is higher than the power it can give, the distortion that results can harm tweeters. You’re more prone to harm woofers if you have too much power. The 100 hz crossover reduces bass below 100 hz from the speakers, reducing the amount of power required.

How do I stop my tweeters from blowing?

“Can you fix a blown speaker?” is, of course, the first query. Yes, you can do it yourself, but it’s not always a good idea. DIY speaker repair is usually short and nasty, and only done on speakers that don’t need to be perfect, such as those in your 20-year-old automobile.

You can use silicon rubber gel to glue your cone back together if it has ripped or split from the fabric surrounding it. Because silicon is flexible, it’s critical to use it; else, you’ll merely produce another tear. This caulk-like gel can be obtained in tubes at Walmart, Home Depot, or any other hardware store.

Some people may even sew the ripped cone together with a needle and thread before gluing it back together with regular glue. I’m sure you can see why it would be a horrible idea.

If only one speaker isn’t working, trace the wiring all the way back to the amplifier and see if any connections have wiggled loose. If none of it works, you’re probably dealing with a coil issue. I wouldn’t bother trying to fix anything unless you’re a skilled electrician.

If we’re talking about a high-end sound system, such as church or auditorium monitors, or your best recording studio monitors, I’d get a professional to come out and fix them. If we’re talking about computer or automobile speakers, they’re inexpensive enough to be replaced entirely.

How do you fix a broken tweeter?

You can prefer to turn up the volume when listening to your favorite music. Speaker distortion is the fastest way to ruin the experience. Why do certain speakers sound great at low volumes yet distort when turned up to maximum? This could happen for a variety of reasons.

A widespread myth about speaker distortion is that the speakers would blow if the amplifier sends too much power. Contrary to popular belief, this is not the case. If your amplifier is underpowering your speakers, you’re much more likely to hear distortion or harm them. Increasing the volume means requesting more power from the amplifier. Your speakers will distort if it is unable to give enough power.

Regardless of the amount of power from the amplifier, speakers of poor build quality can easily be damaged at high volumes. The drivers extend further and faster as the volume increases. Heat builds up inside the speaker as the movement increases. Heat damage might occur if the speaker components are of poor quality. This, in turn, leads to distortion. Damage may not be noticed when your speaker is turned down low, but as the volume rises, it becomes more apparent.

Choosing speakers with high-quality components is the key to avoiding distortion. Additionally, you’ll want to pick an amplifier that has enough power for your system. When you pair high-quality speakers with the correct amplifier, your system will be able to handle music at any volume.

How do you replace a tweeter diaphragm?

The second thing that can bite you is ferrofluid in dome tweeters (usually where utilized). It can dry out in 15 to 20 years, although it can be cleaned out and replaced providing you can take the tweeter apart.
