Nonetheless, it is in the nature of any technology to experience occasional problems, and speakers do blow once in a great while despite the best efforts of the amplification industry to ensure otherwise. Repair or, more likely, replacement. More expensive component loudspeakers that are sold individually, such as those by JBL and Electro-Voice, can often 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.
In that case, learn more about Fender speakers here. Skip to main content. Solid state amplifiyers do bad things when overdiven. I'm no expert but I was always under the impression it was more to do with your amp. Underpowered amplifiers to be specific. The speaker is not going to explode or anything like that. The truth is that high amplifier power almost never destroys a speaker. In most cases, it is a lack of amplifier power that causes damage. The key is to use your speakers with an amplifier that produces sufficient output to drive the speakers to realistic sound volumes without distortion, or "clipping.
Just put some white noise in there and any modereate volume-levels will make the tweeters make indian signals instead of sound-waves Clipping amps will produce spikes which kills speaker-elements. Then again, an amp with sufficient capability to deliver high current will be able to destroy speakerelements if allowed. I remember a demo of a Krell amp that made heavy duty nails both glow and sing, while not bothering the amp too much.
It followed ohm's law pretty decently to 0, ohms before dropping off I was once trying to blow up a cheap 8" woofer with an amp that was rated for W RMS into 8 ohms per channel. I tried my hardest but it was not happening. The speaker was going to rip itself apart but it was not burning the coil. I remembered that clipping is x worse than high power thats clean so I took a 25w no name crap amp and ran it at full clip - the speaker did not move as far but it started to smoke and gave up.
So good clean power does not kill speakers. I am not afraid of putting a W on a pair of bookshelf speakers but I'm terrified of a 10W amp on a set of nice speakers. I will mention however that in extreme cases, you can damage a speaker using too much power.
Everything worked fine for a while, but the speakers were getting noticeably warm. After a few weeks of heavy booming, the speakers eventually gave out, one by one. But it's really not something you should worry about. When you guys mention clipping, does that include that 'bang' or 'pop' you sometimes get from a digital audio file with an error, or when you start or stop a digital tone generator like ToneGen?
Clipping from the source, in the audio range ,Hz will not damage speakers, otherwise you would be replacing speakers after every guitar solo. The source is filtered to be within these audio limits.
As I understand it, the only cliping that will damage speakers is that from the power amplifier connected to it putting out ultrasonic pulses at the leading edge of a square wave. It wouldn't necessarily include that unless the amp was already being pressed too hard, but as a waveform Not in the way I think you'd meant. Not a myth. The electromagnetic-reactive materials in the speakers that allow them to transduce the electrical signals into a mechanical-acoustic action all of them actually, but for the point of this conversation - the voice coils are subject to heating while being induced.
All of the materials have to slough off this heat, but the voice coil is particularly delicate to it. If the voice coil can't dissipate what's being thrown at it, it'll overheat until a segment of it melts, breaking or shorting the circuit.
Clipping blows a speaker by that same means. The square waved energy is much harsher than a smooth musical waveform imparts higher energies and causes greater heat Any vent holes on your speakers should never be blocked either. Always check your plugging and connection jacks when putting your sound system together. When you put the wrong jacks in with the wrong channels, you can blow it. If you want your speakers to last for a long time, you should make sure the area is properly ventilated.
Keeping fans nearby for when you use them heavily will help keep them cool. One way to kiss your speakers goodbye is to connect them to outlets without using voltage protection. For a new speaker, you should do the burn out test.
This helps you ensure there are no manufacturer defects. For speakers that are dead, you either need to replace it or try reconing. Reconing is when you remove all the moving parts and replace them. If you have it fixed professionally, it will be as good as new. The guitar head was likely designed with an original speaker so it might not sound as good as one that goes with other amps.
Bass guitar and PA cabinets should have the speaker replaced with the original ones as specified or at least one that is recommended that is extremely close in specs. You might not be happy though if you loved the way it originally sounded. Heading to your local repair shop might make you happy, or you can tempt fate by doing it yourself.
When you have speakers of any kind, you can damage them by playing them too loud. Many factors come into play with syncing up your equipment plus the type of speakers, the connections, and plenty more.
To avoid troubles, you should always check your setup before turning it up. You should also take steps to maintain your system to prolong the life of your speakers. Make sure you look into the quality of them.
