This method of protection is done by a number of manufactures to stop damage from abuse, however as the tungsten heats up its resistance also increase compressing the sound. This is good for sound reinforcement gear on tweeters to protect it from being over driven and or clipping, but not the best in hi-fi or home use, due to the unwanted insertion losses and dynamic sound compression. However with those cheap speakers you used the sound is so awful anyway who cares, so good video, good work.
Note unlike a ptc this method allows speakers to continue to work even when being over-driven in say a PA on stage live performance application but at a reduced compressed level. Where a ptc will cut off the sound almost completely and would spoil the show.
Bose used this technique in the Bose model 501 Series 1 speakers. The crossover had a clip the lightbulb. This saved my 501 Tweeters from meltdown.
Bell & Howell used one of these on their first solid state 16MM projectors (500"T" series) back in the 60s. They used one side of dual filament bulbs with no bases and called it a "barreter". They used 16 ohm speakers. Another outfit used them but I can't recall who it was. When B&H used the same circuit amp in the next generation of projectors they dropped it from the amplifier. ??
What about a x over @ 110 hrz for the 4ohms
The 8 ohms is a home audio
Which is designed for 2 or 3 way cover set at audio lab.
Allah senden razı olsun.
Electro Voice did this for the Sentry III Series2 along with a relay switch circuit to protect the ST350 tweeters. It's tried true method.
Crazy reading all the clueless comments, without going into the tech of it I'll just say he's exactly right and major manufactures like JBL have been doing it for decades...
Very good!Thanks for the video!:)

Is that dope background music the stuff you bump with those bad boys?
When the speaker goes out... "hold up, i just need to change out the bulb."
Hmmm wonder if you can make a audio compressor with this
Or just learn how to set gains...
I have a audio board wich i want to play with 9v Battery but it is not working. Can you please make video on it. REPLY ME PLEASE
Jbl uses this in their control speakers. Cool idea
Found one in my Bose 601s III
I seen this done before, it also will releave pressure on your amplifier.
I've got an even simpler way to protect speakers against damage. Listen to them. Actually take notice of what you're hearing. If you hear distortion, turn the bastards down. It's not rocket science.
What if you have children who like to play your hifi when you're away from the house? Gonna teach them to hear distortion.
J Wuh just tell your children not to go past a point with the volume knob
(Sorry for bad English)
@@gl-jp8up your english is good! But when i was a child i ignored my father's rules for the music system!
Or use an Amplifier with Clipping protection - saves every speaker, if the Power of them is roughly matched (e.g 400W Amp on a 300W Speaker is no problem, even on the youth club where this combination is used for 20+ years).
Most Speakers (or the tweeters of them) are dead after you have drunken alcohol because this sets your awareness of distortion really down! And distortion is what kills your tweeter, not the high level of sound. Either you stay sober or you use an Amp with Limiter - problem solved.
@@gl-jp8up easier just take the knob off, or decorate it so they wont see it it works
Just install a ptc current limiter to protect your tweeters when blasting your amp.
I've got the bulbs stock on my rcf avent 6000
how your are soldering when the speaker volume is on
That is actually really good idea. Light bulb impedance raises as it gets hot and rising light bulbs’ impedance which is connected to the speaker in series will restrict the power that is going to the speaker. More powerful speaker will need higher wattage bulb. And no, it will not hurt anything. Actially a lot of speaker factories use that method.
bulb connected series in capacitor to positive tweeter ?
Lol
It will absolutely hurt the dynamics, that's why it's only used for tweeters (in PA) and NEVER for woofers.
It's an old school.method of speaker protection. Pretty much like putting a fuse in series with the speaker. I've heard stories from djs who would actually see their bass bins dimly light when they would be blasting them.
The bulb shows no resistance when cool, when you put more power into it the filament lights, gets hot and makes resistance. Taking some of the power from what is being sent to the speaker.
Gumba Sal speaker impedance also rises as the voice coil temperature increases from use.
Different size enclosures also causes peaks and valleys in a speakers impedance across the frequency range.
A speaker's impedance when measured and not in use? is never the same as when it's actually being played.
It’s a good simple and cheap way but they will slightly degrade the sound and might I add when you turned up that music it distorted and the bulb did not bust so if you was to run it loud and distort it like that for half hour or less and that bulb doesn’t bust you will still blow the speakers
If you are using this dont expect good quality of sound
Actually sound improves! Because bulbs acts as tubes ,there is vacum inside and it purifies the sound qwolitty like when passing thru tube amp
Get some Christmas lights and you got dancing lights 😁
Thanks
how about on 2ohms? how many watts?
Does this block any bass?
Self restraint and an understanding of your equipment is the best protection if you want to maintain the sound quality.
Yes, because self restraints has something to do with a DC surge from an amp or DSP.
@@Cultofpersonality09129some albums even with self restraint there are problematic sections of music. Had my infinity rs3b speakers doing a decent work out but nothing crazy then I forgot the damn space ship was going to crash on Pink Floyd dark side of the moon and boom I had two blown emit tweeters.
Couldn't you just use an in-line fuse solution or something similar?
A_YT_Channel By Liam yes
Some peavey speakers use bulb as a fuse on the crossover only for the horns though
Or set gains correct...also..wouldn't a resistor work better
its the same as when you make a series type of connection of two bulb. so when a large amount of hertz signal will pass through the speaker coil becomes hot also.
Except the bulbs impedence will rise much faster than the speaker coil, since the speakers load is more inductant.
Just go with a 2,2uF capacitor in series on each tweeter or if more midrange is required then use 4,7uF capacitors instead...
Who is expecting to hear, "Hey, whats up doods?" After the intro song? Ssundee reference.
And now your amp is driving a completely different ohm's resistance never do this if you care for your amplifier, just because you can, dosent mean you should.
This is not a problem, look closely at an impedance diagram of any speaker with voice coil.
D twist Rewind 7twgxm
I noticed my MBQuart and RockFord crossovers employ this safety feature as well.
If my amp is 20W, what speaker impedance match to gain the maximum capability of my amp? Thanks
Cliff Haerden you don't want to raise ohms because it causes the amp power to drop.

Your can open the box speaker peavey pv115.. In crossover have two unit lamp fuse...for protection tranduser and compression driver....Cause why I choice brand peavey in my sound system... Best in the world..
Mr.John peaveys are below jbl
years ago I saw speakers at a dance that had some sort of built in light which worked like this.
Как называется трек
so no need to install capacitor because of dc bulb
thank you sir

Now your gonna get pulled over cause you used your brake lights as bass blockers 😂🤣
chris vance I hope your brake lights are bigger than that... and if those are the size brake lights you have you must own a Honda Civic
Actually my e36 has those size brake lamps sooo....
This 8 ohm speaker have very big magnet!
Gabriel Vieira that’s a cover
Power is slowly. Bulb series ohm with speaker
I'm from morroco .I have a horn ahoja headphone 50 watts 100 v. What better way to keep it
Toufik Rayan put it inside a cabinet and dont use it
Use 2 speaker in series...two 25w in series can handle handle double voltage ....at 100hz sound output of the amplifier in bridge mode is it's rail voltage ...
I like that u should try it with an led light
L.E.D. would burn out instantly.
hı what is the difference ??
This idea is applicable only with PA systems. F0r home and car systems it may damage the ic due to improper impedence.
You're just diverting the current for the speakers.. why dont you just match the speakers with your amplifier?
What size of speaker inch ? 8 ohm and 3 ohm ?? And watt???
Atomic t c g what speaker? The black speaker or the other? The black are an sony xplod 50w 5inch speaker
Good ☺

Or you can use a revolutionary thing called a crossover
Hola! No entiendo nada de esto. Para que colocar un bombillo en un speaker y que encienda la luz ?
Saberio Eliseo Mannarino Ortega Para proteger al speaker en caso de sobrevoltaje. Aunque yo lo haría utilizando un fusible...
puede dañar el amplificador
Kiker tenía un ser de medios con esa funcion. Yo fui afortunado en comprar esa serie la cual compre en año 2002 hoy en 2018 aún están jalando sólo que los crossovers que hacían la funcion los lleve con un instalador a que los pusiera en una golf y nunca los instalo.
Para cuando me Di cuenta de esto sólo dijo, no no los trajiste😠😠😠
I've seen this type of connection with a bulb in series , The Jensen speaker box network has it....
Edifier Bass every bose I ever took apart has built into their crossover Networks
yes.
The light has it's own resistance so adding the light bulb in series will completely change the load you're putting on your amplifier and this in time will hurt your amp. and also the quailty impact from running it through a small coil like that must be pretty bad..
Fuskers raising the impedance won't hurt the amp. Having inconsistent ohm loads on different channels won't either it will make it more difficult to level match the speakers though if the resister in this case a light bulb aren't consistent.
Several cross over designs use this bulb design on the tweeter circuit to reduce overall power going to the tweeter. For example the Memphis audio mcc6 components. Which sound quite good and rival much more expensive speakers when installed correctly. The new Memphis viv components simply swap the light bulb for an air core resister. Both achieve the same thing
Kyle Vanwinkle raising does affect the output. Read up on amplifiers.
@@vsmichael1
May effect output.
But the question was damaging an amplifier. WHICH IT WILL NOT.
And companies like JBL, BOSE and PEAVEY have been doing this for some time too.
But what do they know, right 😂 .
When the lamp is warming up, the resistance increases and destroys the damping factor of the amp. That leads to sloppy bass response even before the speaker is in any danger. No danger to the amp though (as long as it's not a tube amp, they don't like mismatches in impedance)
+TANGLDWEB what are you talking about ...no company does this ...they use correct wiring solutions...you thick fool ...someone told you that and you believed them. . do you think Santa is real still ....????
kuj bol kar xplan bhi kar diya karo bro
Instead select appropriate speaker for your amp or vice versa. buying a power amp for tiny speakers and then adding resister to protect it is waste of money and power.
Not all speakers are used for music playback some of them are used to amplify live stuff coming frome microphones so some times happens to go a little feedbacky a very dangerous condition especially for tweeters. So this is a good and cheap solution to save them.
i dotn think so, maybe u can put a resistor for resistance
The bulb will increase resistance with more power
@@FSXgta and who df wants that. The bulb will heat up and drop the power on speaker producing weird peaks in music
Break The glass And it Works better
Now in 2018, there are better ways of dealing with this, such as PPTC. Look up the desired current and voltage levels and choose the right one.
Editor?
Thanks for this knowledge
Shazad Zaidi Please don’t do it, your amp have to drive more Ohms now, that will shorten the live of your amp
Non Age Restricted well if you put your speakers in parallel then you don't have to worry about it... half the ohms and now the ohm rating is just a wee bit higher putting it back to normal. It's Common Sense dude.
If i know right, higher resistance is not a big deal for the amp, but the lower resistance is an amp killer... But this lamp will not save the speaker from dc current, if u want to prevent dc voltage u should use a high capacity not polarized capacitor :) like 30-40uF 400V (it enough for most common uses)
Theres something invented for that its called a fuse
Dirty Potatoes fuse won't protect speakers against DC. Fuse just protect against overcurrents.
Relays are the best way to protect speakers from DC.
HYOSAIZERO or you just turn your gain down so it's not clipping and sending the DC current to a speaker like a nincompoop. this literally doesn't teach people anything!
If your amp gets blown, having the gain on low doesn't save your speaker. Neither does the bulb and neither does the fuse.
@@tomkocur only ways to blower amp is eitherhaving your game maxed out so it's sending a shity clip signal all the time and it overheats or you let your voltage drop to a dangerous level any damage components such as capacitors and such. or you have a lighter job that looks like it was rigged up by a spider monkey with epilepsy! Adding a light bulb could add ohms to your final ohm load and also damage your amp... this is trash if you want to be in the audio you got to learn something you can't take shortcuts with light bulbs
Tyler Herod Amp can fail anytime for any reason. Higher impedance (more ohms) doesn't damage the amp and neither does low voltage
A professional speaker has system protection board .

This is just series resistance you can get same results with just one power resistor but in both cases it limits power flowing to the speaker so is it same when you decrease volume with is done with potenciometer and potenciometer is just special type of resistor. So it mean you don't need to build this circuit to protect your speaker coil, just don't use maximum volume
And now ur amp is on fire 😊
Company's already do that. You can still blow the speaker.
Somehow i fail to see the logic in this, its distortion that damages speakers so turning the gain down will help since speakers cannot defrienciate between power and distortion. With external amps running speakers, just turn the gains down. Another factor is a quality amp, if you have one that produces less distortion then this contraption is friutless not to mention time consuming.
This is a ghetto method, but so is your lack of knowledge.
Why don't you juste put a fuse?
its better to put fuse, impedance of speaker will not be affected.
The light is just acting as clip indicator , as everyone can see the light is turning on when the speaker is distorting..!
Enlarge volume again whether to fire the bulb does not 😂😂😂😂😂
Noooo eso no se ase con el tipo de lampara que usaste porque tenes que subir mucho el bolumen para que guncione ahora yo lo haría con led
What he is doing is showing clipping. When the amp clips it outputs DC and that lights the blub. DC is bad for speakers. If the blub lights up back the volume down and that saves your speakers
Or just use a fucking circuit breaker. Almost 0 resistance and it protects your speaker from an overload. If you want to do that

Or you can use a fuse or a polyswitch. Or waste time removing the driver and soldering in another bulb every time you overdrive the speaker. Your idea does work but it's not really a solution.
Ovis koromban csináltam ezt. Kész vicc a videó
your gonna blow the amp and the speaker

12 v 25 watt
This is the absolute dumbest way to prevent speaker damage ...hands down!
Actually not. As the bulb glows more, the impedance rises, letting in less power for the speaker
Aaaaa your nails
Isn't voltage that kills speakers its clipping that kills thems
chad smith I'm pretty sure if you quadruple the amount of voltage needed for the speaker I'm pretty sure clipping has nothing to do with it at that point. It's an instant one shot destroy of a speaker.
ExTr3m3 BASS. Lies bruh i seen speakers take tripel the amont of power all day my freind has a sundow zv3 on 5krms and shit dosnt even burn or get hot now your door speakers and high range speakers are a diffrent stroy
ExTr3m3 BASS also voltage is what you use to set the power range the only reason the leight started to flicker is becuse of cliping. Cliping is where the amp stops puting out ac voltages and just put out dc voltage out to tge speaker
ExTr3m3 BASS. Chad is right th-cam.com/video/9PF32APSjrk/w-d-xo.html
ExTr3m3 BASS. Also any speaker taking in voltages higher then recommended isn't good for them but speakers run off of voltage so the lamp bulb is just a clip detector
Burns explode and fire!!!!!
Why dont destroy it bro 5000. Volts
А смысл?
Or maybe simply use a Capacitor?
A capacitor would only change the crossover freq. at best. In case of overload or clipping it would do nothing.
🤔
@@armandorellegue1137 Hi, for high frequencies ( as with a clipping amp) the capacitor is in effect a 0 Ohm series resistor so will form no safeguard against overloading the tweeter.
OK you had the dc current problem solved, now it remains to solve the low frequency response, tweeter overloading, clipping, and World hunger.
Y no es mas facil poner un fusible? 😂
