just installed VLC PLAYER guys on my laptop "DELL" :sarcastic:  and used it for sometime , few days back my media player got crashed . anyway i had to use VLC PLAYER , i listen to hard metal so i raised the sound to 200% , well the sound was great after just 15 minutes or something , i heard strong noise from the left speaker , i thought something is wrong with the software but no sire , my speaker is spoiled :D  , the VLC got my laptop speaker dead , i just want to ask the creator of this program , does he have any idea how hard it's gonna be in a place like this to fix my laptop and how the hell i am gonna get the spare part i need , i am crying people this sucks for sure , i know what u probably gonna say it's dell 's problem but VLC had to tell me the risk or anything , anything that could tell me this was gonna happened :??:  i don't understand how could such app be available to download and u something if u raise it to %200 u gonna get ur self only bad sound

guys , last thing does it have to be replaced , can't i just fix it or something :(

You jacked the sound all the way up, and blame it on VLC?

No offence, but that was completely your fault. You should know that 200% is well above what you should put the volume up to. Common sense.

He is being fair - you cranked the sound all the way up.
Most stereos will allow almost 200% because not all sources are equal. Common sense can't be downloaded with vlc.

ah , well and it's not VLC 's fault at all to damage ur speaker after only 15 minutes if it was wrong then why did they put such option from first place without even a notice

I just asked my six year old niece what would happen if turned a speaker up twice as loud as it's meant to go.

She said it will blow up.

She has more common sense then you.

Software is irrelevant, 5w speaker will only take 5w. Software can say 1000000% and it still won't take more power. It is common for laptop speakers to be cheap and break easily. You are not the only one to blame software. But the speaker will only input a max signal that its driver allows or clipping occurs. When clipping occurs, the speaker is sustaining its max power for an extended amount of time. Low quality components will not handle their max for very long and then blow. Also the volume level is relative, so a strong input at 10% can be equal to a weak signal at 400%, both maxing your speaker.

It's not the software . It was a cheap speaker that couldnt handle working at 100% . You cant bypass the hardware or the preamp specs with software .

ding ding ding! we have a winner!

though we can get into a discussion about *which frequency* would blow what type of speaker but that is an excellent explanation.

Hey, cut the poor student some slack. I just cranked up hard metal to 200% percent and now my ears are blown.
No warning.

just buy speakers probably be cheaper than trying to fix the laptop speakers and you would get better sound quality too.

Yeah, sorry dude it is totally your own fault. Think about it, if you set something to 200% or 2x what is normal don't you think that can cause problems?

Common sense... if you were to eat 200% more per day I would assume you would think that you will gain weight faster. If you bake something and the instructions tells you to set the oven to 300F, but you set it to 600F does that mean it cooks 2x faster?

For whatever reason it just brought back that memory when people sued Apple back in 2006 or so because setting their iPods to the maximum volume damaged their hearing. Nothing related to this issue other than common sense... the louder something is the more likely it will damage your ears. Perhaps they were too thickheaded to know that and maybe they should have downloaded hack for their iPod which doubles the volume. Maybe if they listened to a message at 2x the max volume they would have heard it when it says "LOUD MUSIC CAN DAMAGE YOUR HEARING".

Also reminds me of the scene in This Is Spinal Tap, where Nigel is explaining to a reporter why his amp goes up to volume 11...

Once more , this 200% refers to the source , not to the max wattage . YOU CANNOT excede max specs with software . All you can do is come closer to the 100% of the wattage dictated by your amp + preamp specs . This setting in VLC , is about correcting the source (the video or audio) playing , which can be really low sometimes . That is also what normalise does , corrects your source depending on a preset , makes low sources louder and high sources lower , so that they sound almost the same . Think before you post guys . This guys speaker blew up because there was something wrong with it and as every tech worth his salt knows , stressing faulty equipment can do that .

RMA it if it is within warranty .

When the incoming signal from the audio source is particularly loud, it will overdrive the amplifier. This causes the amp to "clip" or distort, and that sound is passed to the speakers. Not only does this cause the amplifier to overheat and wear out more quickly, but the loud-level high harmonics in the distortion can destroy the speaker. This can occur even if the amp is underpowered for the speakers when the gain is too high.

Oh great , I will record a video called "this will blow your speakers" , edit it to 5000% audio gain , upload it and have fun then ! On second thought people are idiots sometimes and they already tried it ..... it DIDNT WORK .... :p  That's because distortion or clipping , will move the wattage to less than double , so every manufacturer drives his speaker with a less than half amp . Therefore no blown speaker . A 5 watt amp cant blow an 11 watt speaker . Even in a worst case scenario . If the manufacturer is stupid enough to not follow this simple rule .... he should RMA them .

Clipping is a common cause of blown tweeters. They are basically square waves instead of sine waves.

In the case of under-powering, the driver is blown because the amplifier is driven to the point that it can no longer amplify the signal. The amp tries to generate the amplified version of the input waveform, but runs out of "headroom" before the full wave is generated. The result is a square wave. The sinusoidal version of the waveform is only partially generated and the result is a square wave with a "plateau" on the top. The "plateau" is pretty much a DC current at that point. DC in large enough amounts or long enough times is what burns up speakers.

The driver is only driven part of the way in or out, but it is held in a suspended position at the top of the square wave the amp is generating. The result is the speaker is in a near DC state and the constant voltage without any corresponding movement causes the windings of the voice coil to heat up. Eventually the heat is too great for the windings and they burn up.

Hi :) 

Its NOT hard to fix, its the expensive labour.. we would charge in the UK a minimum of 1 hours labour (£50) plus the new speaker to strip the laptop and solder in a new speaker...

OR you could just plug in a decent set of speakers to the audio jack and blow your ears off that way...at 200%

All the best Brett :)

Jag - well done on the clipping explanation. I used to sell stereos part time in the 80s - had more people blow their 400W Cerwin-Vegas with a cheap under powered amplifier.

BTW StefanGR - you do not know what you are talking about.
-Bruce
Many 100Watt speakers have been blown by a 50 W Amp - when it clips.
Speakers are impedances - the have a nominal impedance from 20-20,000Hz of 4-8Ohms. When clipping occurs short bursts of DC(direct current - 0Hz) go through your speakers. Dc resistance may be fractions of an OHM. Very high currents will flow through the voice coils making them very hot - will burn the enamel off the copper wire.

The option is there due to different average volume results in encoding. It's far preferable audio quality wise to increase the source by 20% or 100% vs your amplifier having to be set 20% over normal.

I actually believe this is an especially useful setting I use regularly that should be in all players. If my wife and I are watching a video on my laptop while flying its nice to be able to compensate for the laptop's audio amp having to drive two sets of headphones via a splitter.

Here ya go <$30 fix, and its purple to boot.
