Epic speaker smoker story: When I was a HiFi salesman back in the 90’s, I had a customer who bought Martin-Logan Quest’s (a big electrostatic hybrid with a 48” x 28” ‘stat panel paired with a big honking 12” woofer. The amp was a Sunfire Signature, 600 watts into 8 ohms and 1200 watts into 4 ohms. He installed this system in a 3rd floor listening room. One day he decided to work with power woodworking tools in his basement and he turned up his stereo located FOUR FLOORS UP loud enough to hear over the power tools. Needless to say that after a while the ‘stat panels went silent. He sheepishly brought the speakers in for service and upon opening them up and testing them we found that both the ‘stat panels and woofers survived without damage but the really big fist-sized polypropylene crossover capacitor rated at 600 volts went up in flames! You could see the flame plume burns on the inside of the enclosure. And yes, it smelled to high heaven in there. Martin-Logan, bless their hearts, covered the repair under warranty and used the information to update their crossovers.
I once had a set up that, when abused, could be heard at least four blocks away, because that was how far away I sometimes had to park from my place down by the beach in the summer time, and I had roommates who were oblivious to overdriven woofers, as were the speakers themselves. The house I lived in had a traditional worn the neighbors ahead of time costume dance party celebrating after new years that ran excessive sound levels well into morning. The next day, the speakers were fine, except somebody stole the JBL logo from one speaker, as a keepsake I suppose, but my top of the line marantz receiver was hurting, having developed a slight buzz in the front end. 125 watts into speakers you could drive with a pocket radio gets pretty loud, and dancers were still screaming to turn it up.
Oh man this brings back memories, I can smell it from here. Use to do this a lot, on purpose and accident, when you could buy speakers from the Salvation Army store for like $10 and a seriously powerful receiver for another $25, good times, and a great vid Randy!!!
I had an electronics teacher in H.S. that had us all build a circuit project with a BIG OL' can capacitor. It was intentionally built with a resistor that was too small so that the cap would go kaboom. He had us place a dome over the circuit (the domes were clear plastic and came from old reel-to-reel computer tapes) and turn the power on to see and smell the results. The caps would pop and spew thick white smoke, enough to fill the dome. We were to remember what that smells like and DON'T breathe it in. 😵
Burning caps are a nasty smell. The only thing worse is a burnt up race car transmission. I dare anyone to be there when you open the transmission case up and NOT puke or nearly puke.
I damaged, (thought I blew up) , a prototype 18" Peavey Black Widow subwoofer a few years ago. I've had it and been using it since around 1991. It's had a variety of power amps driving it and it never came close to frying it, until....I bridged a Carver M200t and really pushed it. The smell was terrible and the smoke as well. I bought a new basket for it and it didn't fit. That's when I found out I had a prototype and not a production speaker. Well I wasn't having any of this and measured the voice coil resistance and it was still good. So I reformed the crustified mutated coil , with a file and a micrometer to try to maintain roundness and wah la! It's back to rocking the room again. While not an audiophile speaker per say, it's one tough cookie. Thanks for another fun vid Randy.
Back in the 70’s while working at Tech hi-fi in NYC we hooked up a phase linear 700b power amp to some Cerwin Vega speaker, the woofer caught on fire .
I ended up with my sister's vintage 70s Marantz/Sansui/Teac system because she moved in with her best friend who had a gigantic Phase Linear system. I swear the amps weighed more than their couch. Her friend got the system as a result of a divorce and I'm 90% sure that if I asked she would have either given it to me or sold it to me when she moved out.
What joy! A video showing me people blowing stuff up. My day is made. Thank you for sharing this with us all and how not to treat your equipment. 😂 Take care and all the best.
The question is how many dB did you get before it blew? (or how many watts). That could help people know how far they can safely push the speaker in normal use.
The poor specs of the amp (.1% THD) is what blew that speaker. Not the wattage. Distortion blows speakers more than anything else. Clipping is like sending DC voltage in spikes to a speaker and it cooks the voicecoils.
Those Wharfedales do look very huggable! For future speaker killing demos, be sure to power off the amplifier as soon the threshold of murder has been reached. The deceased speaker's impedance will drop drastically and you don't want to risk any damage to the Emotiva amp, which is actually a witness to the crime at hand (but also the murderer I suppose?).
I repaired office machines for 40 years and I am very familiar with that burnt electric smell. Now do the Letterman thing and throw some speakers off a tall building.
Heh. Thanks for taking me back to the early 70's and the mandatory music appreciation course I was enrolled in. Great instructor who was a professional musician on the side. He had the classroom sound system hooked up to his own gear one day. Put on his rare and treasured vinyl of the Berlin Philharmonic performing Wagner's Ring Cycle, and played cuts. At one point two full orchestras were playing with an additional brass section. The desks were shaking...and then one speaker started smoking, squealed and popped, followed quickly by a second before he could kill it. It wasn't his kit that blew. :)
You should totally make this a part of your show once a week. Keep a running score of how much volume blew each speaker while playing the same track! Definitely RUclips material that know one is doing.
Agreed. Do it once a week or at regular intervals. Only next time I want to see the woofer blow a hole, lol. Maybe get used speakers from craigslist to make it cheap?
I thought for sure, you would have chosen the Polk T15 speaker stands for this video (haha - the first time in a VERY old video way back, that you called them "speaker stands" - I died!). Loved the video! Also, we need an updated speaker tier/rating/rankings video, and also one for the inexpensive Ayima, Fosi, etc. amps. That would be fantastic!!!!
@@cheapaudioman That is pretty hilarious. Is there anywhere I can send you a photo of the CAM offfice set up I jut put together? I think you would be proud.
We use to love doin that years ago on old 6x9s and el cheapos, some would catch fire literally. That woofer held up better on those hits than I expected.
The woofer is rated to handle 40 watts RMS, the enclosure Dayton designed for it (small) does well to maximize power handling over pure bass extension (large), looks like they did their homework.
Love those big Emotiva amps. Had a pair of the original XPA 1s they were great amps. Really should've hung onto em. Would be interested to know how the newer (module based) versions compare for sound and measurements.
I used to do this when I was a teenager. Had a powerful pro amp and me and my buddy used to pump hundreds of watts to super cheap speakers. BBBRRRRGGGHHH! They would make one last sound like the A10 Warhog's cannon before releasing magic smoke. pieces of woofer cone would sometimes fly across my bedroom. Strangely satisfying for some reason.
Not bad, it also gave plenty of warning "I'm... PLEASE! I'm hurt'n! Turn it down!!" way before taking permanent damage.... Aaah, you shu'd have fried the tweetah too tho!
I remember back in HS I blew out the woofers on my Wharfdale speakers with a Dynaco 120 Power Amp. I wonder how much peak power that speaker took before it "popped" ?
We blew up two pairs of speakers with the same Onkyo receiver. The problem with that receiver was that the input levels of the radio was easily twice that of CD, TV (aux), tape, and phono inputs. And when the power flickered during a storm or whatever, the receiver would turn ON, and default to Radio, and since we never listened to radio, the volume knob was always set higher for CD or TV. So many times the power would flick off and on in the middle of the night, and we would have to jump out of bed, run downstairs and turn off the stereo. Well... twice we weren't home when this happened. And twice we came home to blown woofers. Can't imagine what the neighbors thought.
really wished you did more with it before you lighted it up, I would love to see how long the woofer hold up with brownian noise driven to the rated power and then some, then record the power/loudness just before cone breakup, before taking it towards the magic smoke if you burn enough of them you can probably set up a small database as to how inflated/conservative each manufacturer rates the power handling of their speakers
I think th only speakers I've ever blown were factory car speakers, but I hooked some Cerwin Vega towers up to a Pioneer rack system & around 30 mins smoke was pouring out of that amp & it was fried😅 I'm glad it happened b/c that made me go to a hifi shop & start building a much better system
Randy! I have so many questions! How high did you turn up the amplifier before it blew? How much SPL was that speaker out putting before it blew? What physically happens when a speaker blows? Did the voice coil actually break or did it just gets so hot that It melted some components? I expected the actual diaphragm of the woofer to be damaged, but that doesn’t seem to be the case I want to learn more! And I definitely want you to blow up more expensive speakers. I want to see how far you can push a Klipsch or a Polk’s speaker with high SPL output before they blow!
You could hear the voice coil assembly slamming against the back of the magnet, but what happened was the current fused the voice coil wire and it open circuited. Because some of the wire melted, it didn’t slide in and out easy as you saw the video.
Oh please before I spend a schitt load of greenbacks for Klipsch forte 4.. you really love to know how much power it would take to melt their coils.. so what do you say hun sometime in the next 3 weeks it is now me for and I kind of thought I made it my mind about what I want to do when it comes to creating the most eclectic 9.4 surround in an 18 wide 25ft long room where three sides of it are concrete 16in fire block in one wall has a door and a window
Dear Randy, I have the suggestion to end all suggestions for you...This may get you a huge bump in your subscriber count at a level you never dared to imagine...if you do exactly as I describe below... In an outdoor setting have a set of speakers playing music at a reasonable volume, then set them on fire while the music is playing. While they are burning, you, Randy the Cheapaudioman, will put on a Tiki mask and perform a war dance around the burning speakers while waving a plunger in the air. You will then conclude this spectacle by carefully placing the Tiki mask on the ground and give it an elbow-drop. Cheers! -Moony
Just in case you're not aware. It's easier to blow speakers with low power amp than high power amp. The low power will go in heavy distortion which is fatal to speakers. With high power, when you hear your speakers having trouble, is simply because you reached the maximum capacity of your speaker. This is a fact in audio.
Yes, but in that case, it will generally be the Tweeters that fail, not the woofers. A underpowered amplifier will go into clipping, which generates high frequency noise-this will kill tweeters. A high powered amplifier, if turned up enough, WILL kill woofers.
@@1957CRAZYDJ Yes, they can, but generally, a low output amplifier will burn out tweeters, and a high output amplifier will tend to burn out woofers. Of course, this is not ALWAYS the case however.
Well, okay. The higher end Emotivas put out some juice. For a more realistic example, spool up Spielberg’s “War of the Worlds”, play it at reference level, and watch what happens to the drivers in some of the smaller audiophile-grade bookshelf speakers. Warning: wear serious eye protection and a ballistic vest.
In high school electric shop, thanks to me, and my friend, the enabler, we wired a 5” speaker directly to a line cord and plugged it in. We actually heard 60 cycle hum (60 Hz) for a few seconds, and then poof, smoke, fire, and then an ass chewing from the teacher! 😂😂😂 A good time was had by all !! 🥳🥳 Edit: Using the fire extinguisher made sure we got caught lol
I am not sure I understand what is the purpose of driving a speaker to the point of destruction. I didn't see any scientific measurements being done. So, I can only assume that this is for entertainment. Makes me wonder if destroying things should be a form of entertainment?
The Emotiva XPA Gen-3 amps have watts, but they are lacking enough global feedback, so the Class-H rail switching design produces picket-fence distortion harmonics that are excessive. With enough global feedback including the output stage and speaker load, you can get low distortion performance from just about any amp - even Class-D radio noise generators - so it is an oversight on Emotiva's part to neglect this.
Silly me, I thought pyrotechnics were going to be used and I was going to relive my childhood. So what clock position was the volume knob at when you heard the final "Thar she blows"? Do you think the speaker could have taken more volume with a mellow, acoustical ballad song?
Just realized my post may ruffle feathers...coil winding wire, diameter, glue, former attachment, all can get too hot by twisting the knob. Don't blame the power, blame the user....or the speaker designer. 😅
Totally off topic but have you checked out the Geshelli J2 Dac Socketed version? I had a Aiyima A07 with Sparkos Labs Op Amps that I no longer use. Let's just say a J2 with Sparkos Labs Op Amps (1 for RCA, 2 for XLR) sounds amazing! Just came in today!
Gee Randy, with as much power as that DR1 amp can put out, maybe a set of welding connected to it could make it more useful than just an audio amplifier. 😁

Hi Randy, try a low power amp and watch the tweeter go first , this will demonstrate what clipping does to a tweeter.

Sweet I've never seen a speaker blown up. Good vid.
This is fun...ive never seen a speaker (woofer and/or tweeter) destroyed by high power; all damage I ever saw was from amps overdrive into clipping!
I'm here for this kind of content 😅
We blew up two pairs of speakers with the same Onkyo receiver. The problem with that receiver was that the input levels of the radio was easily twice that of CD, TV (aux), tape, and phono inputs. And when the power flickered during a storm or whatever, the receiver would turn ON, and default to Radio, and since we never listened to radio, the volume knob was always set higher for CD or TV. So many times the power would flick off and on in the middle of the night, and we would have to jump out of bed, run downstairs and turn off the stereo. Well... twice we weren't home when this happened. And twice we came home to blown woofers. Can't imagine what the neighbors thought.
really wished you did more with it before you lighted it up, I would love to see how long the woofer hold up with brownian noise driven to the rated power and then some, then record the power/loudness just before cone breakup, before taking it towards the magic smoke
if you burn enough of them you can probably set up a small database as to how inflated/conservative each manufacturer rates the power handling of their speakers
I need to get more smarter to do that
I think th only speakers I've ever blown were factory car speakers, but I hooked some Cerwin Vega towers up to a Pioneer rack system & around 30 mins smoke was pouring out of that amp & it was fried😅 I'm glad it happened b/c that made me go to a hifi shop & start building a much better system
Disco Destruction is back! We used to blow up speakers from cheap radios with a big old Phase Linear amp. They usually just went up in smoke.
Randy! I have so many questions! How high did you turn up the amplifier before it blew? How much SPL was that speaker out putting before it blew? What physically happens when a speaker blows? Did the voice coil actually break or did it just gets so hot that It melted some components?

I want to see how far you can push a Klipsch or a Polk’s speaker with high SPL output before they blow!
You could hear the voice coil assembly slamming against the back of the magnet, but what happened was the current fused the voice coil wire and it open circuited. Because some of the wire melted, it didn’t slide in and out easy as you saw the video.
"BOOM!" goes the dynamite...
Just did that to a cheap subwoofer with a Crown amp . It let the smoke out

My inner 'Uncle Fester' is jealous!!😄
Great vid Randy!
EMOTIVA POWER. cant get no better than that. Cool vid.
Destruction Thursday! Fun with speakers!
Is the failure due to a capacitor blowing or the failure of the magnet-driver assembly just overheating and failing? From your video sounds like both.
The beauty of this is, you can easily replace the woofer and do it again
Yes. Sure. Try with Nautilius. 😃
That was Awesome, Funny as !@#$%!! The Speaker did better for longer than I thought it would!!
Awesome Video Brother!!
I had 2 6x9s that the tweeters went out on so i hooked them up to my 1000 watt car amp till they blew smoke signals it was so much fun

That’s what happens when you fry the voice coil. 😵💫 You could’ve easily fried that woofer with DC !😉
In high school electric shop, thanks to me, and my friend, the enabler, we wired a 5” speaker directly to a line cord and plugged it in. We actually heard 60 cycle hum (60 Hz) for a few seconds, and then poof, smoke, fire, and then an ass chewing from the teacher! 😂😂😂 A good time was had by all !! 🥳🥳
Edit: Using the fire extinguisher made sure we got caught lol
I have the EMOTIVA XPA-DR3 running my LCR!!! SUPER STRONG amp!!!!
I am not sure I understand what is the purpose of driving a speaker to the point of destruction. I didn't see any scientific measurements being done. So, I can only assume that this is for entertainment. Makes me wonder if destroying things should be a form of entertainment?
I LOVE IT!!!!!! YOU ROCK!!! YEAH MAN LET'S BLOW UP SOME MORE STUFF!!
Well............... That was different! 😂👍
Can you blow up a pair of Wilson Audio Speakers? For fun!
50 odd years ago a friend of mine did this to his videotone Mini max , the tweeters popped out with a puff of light smoke
Blow up some magico speakers.😊
Cool man! Love it!
The Emotiva XPA Gen-3 amps have watts, but they are lacking enough global feedback, so the Class-H rail switching design produces picket-fence distortion harmonics that are excessive. With enough global feedback including the output stage and speaker load, you can get low distortion performance from just about any amp - even Class-D radio noise generators - so it is an oversight on Emotiva's part to neglect this.
sign of a good amp when the tweeter survives...........
Silly me, I thought pyrotechnics were going to be used and I was going to relive my childhood. So what clock position was the volume knob at when you heard the final "Thar she blows"? Do you think the speaker could have taken more volume with a mellow, acoustical ballad song?
Randy. It's never too much power, so something else made it fail. Did you cut the speaker voice coil out? Could you post pictures?
Just realized my post may ruffle feathers...coil winding wire, diameter, glue, former attachment, all can get too hot by twisting the knob. Don't blame the power, blame the user....or the speaker designer. 😅
How loud did you have to go? Would be cool if you used an SPL to see
Wow that's speaker is a clone of the B2+. (well, minus the ribbon tweeter and the hexagonal frame around the woofer).
Should have hooked a multimeter up to the outputs to get an idea of what wattage it was taking when it gave up the ghost
Turns out if you smelled it, you did indeed dealt it.
Presumably people are buying those amps, but what speakers are designed to be paired with 1000W amps?
I CRANK my 150 wpc BasX quite often 🤪 and never had any problem with my 4 ohm Triads.
Totally off topic but have you checked out the Geshelli J2 Dac Socketed version? I had a Aiyima A07 with Sparkos Labs Op Amps that I no longer use. Let's just say a J2 with Sparkos Labs Op Amps (1 for RCA, 2 for XLR) sounds amazing! Just came in today!
Kinda lucky the Emotiva did'nt go pop as the load suddenly drops to 0 ohms! Fun though😊
Yes!!! More amp vs speaker videos please 😂 it would be great if you had a way to measure the amplifiers power output to the speaker, is that possible?
Was this a David Letterman bit with Larry Bud Melman?
Take 2 or 3 4ohm speakers and wire them in parallel...let's blow some cheap chi-fi amps 💥
I made a DIY bookshelf with a 6.5 and can do 32hz solid...
the blowup man has arrived...
Do another one but with square wave (distortion).
Yes, blow up more!!! It would be nice if you could be a bit scientific about it and measure how many watts the amp is putting out when it pops.
Gee Randy, with as much power as that DR1 amp can put out, maybe a set of welding connected to it could make it more useful than just an audio amplifier. 😁
Zero warranty coverage!! Whooops! 😅⚡️🔥👀
What are your thoughts on the Dayton HT series amps?
