@Paul Weston It's literally built to the application he needs. I know what he had and needed more. For a normal musical application I wouldn't build it this way, or recommend it, but he had a specific need I built a specific sub for.
Paul Weston

​@EMF Audio EMF, much respect. Essentilally, he's getting 12" subs with 10" cones. It just seems like the point IS to have bragging rights on the size, not necessarily needing that driver. , but he's not going to know (at that time) how it sounds until it's tested with a new set of T/S parameter in order to build a proper enclosure. I wouldn't doubt it ends up mounted inverted or in a box with a large plexiglass window. You do really nice work and I'm very impressed. Maybe I'm jumping to conclusions on his reasoning. I was just speculating. Thanks man

Very cool video, wondering how you quantify the specifications of this woofer? For example, say the coil is rated for 1000w, and everything works good, you take it out, put in new basket, different excursion rate, how do you know how much power or amplitude it can have before having mechanical interference from too much excursion? or is it limited by the how much displacement the surround has first?
EMF Audio
EMF Audio 5 days ago
For starters, a coil will never be rated for a power level. If someplace does that, they're most definitely lying. The coil and the motor have to work together to get a thermal power rating. A mechanical power rating is different, that's the point where you reach mechanical limits before thermal. An experienced designer or builder should have a pretty good idea of where those limits will be but sometimes you just have to build something, test it, and see how it handles it and rate accordingly or make changes.

Biggest 10" that i know that can be purchased is the Alphard Deaf Bonce DB-10F3 (old version of the DB-310) 27kg 10" beast. I have one, handles 3000w like a champ. The person who owned the sub before me burped 160+dB @ 12000w with it. Crazy 10".

So you can put a 600° soldering iron on the cone???
EMF Audio
EMF Audio 13 days ago
@MonsterHouse22 600 degrees is the tip temperature, not the temperature of the surface below what you're soldering. You can push on the lead and get solder on it for a few seconds and the paper below it will never get very hot. It doesn't even leave a mark, and the glue goes over that spot anyway.
MonsterHouse22
MonsterHouse22 13 days ago
@EMF Audio so how would you solder the leads if you can't solder on the cone, or does it not matter if you burn a hole beneath the dust cap?
EMF Audio
EMF Audio 13 days ago
The point was not 600, you're also referring to pure paper and not any time of mixture which happens in cones. It's possible they can have bonding agents with a lower flashpoint, but some are also infused with fiberglass.

I would scuff up the basket surfaces before it's anywhere near the magnet. No need in risking the possibility of getting metal dust in the magnets voice coil bore. You'll never blow every little piece out. It's gotta stay clean or else all that hard work is wasted. I'm sure it's fine though, he's built a lot more speakers than me. I'm curious to know though, Is there a special industry norm way to get metal dust out, or is that not ever an issue?
Andrew J
Andrew J 19 days ago
Thanks for the info. Makes sense.
EMF Audio
EMF Audio 19 days ago
It's scuffing, not sanding. No metal is removed, the paint is getting scratched up is all. There isn't anything to blow out because there isn't anything there. What gets removed is cleaned up with a microfiber on the surface. The only dust issue you'd ever have is contamination from other things, which isn't an issue for us as the build room is climate controlled and separate from everything else, including offices.

You need to keep the coil gap covered with masking tape whenever you have a dismantled speaker/driver laying about......anyway.......this build is hilarious and I can confidently say that that driver will be no more "noisy" than one with half the power, that cone will only ever displace so much air, it doesn't matter how much electromotive force you apply!
iseeolly
iseeolly Month ago
@EMF Audio SIr, better to keep your mouth shut and let people think you are an idiot than to open it and prove the point. You seam to have gone on the attack, in front of all your customers ??? Very odd descision?? Real world experience? .....working in a factory shipping speakers and drivers by the truck-load? Millions of pounds worth every year???? Are you really suggesting that people using thousands of pounds worth of equipment for an audience of 100,000 people at Glastonbury or the Super Bowl know less than somebody making a bit of bling for their truck??? ....and on the domestic front....if somebody is paying $25,000 for a pair of Kef Hi-Fi speakers then they need to be good... I was employed as a engineer, not sure why you presume otherwise with no evidence. I was a quality control technician for millions of pounds worth of product, both professional (celestion) making drivers for Turbosound, EAW, Mackie, Marshall, Bang and Olufsen etc...and for Kef producing high-end audiophile equipment. I tested and measured individual driver components as the reached the factory...even destruction tested voice coils. I also oversaw the production-line to ensure consistency and investigated any production problems if the finished speakers/diver/tweeters/compression drivers did not perform or failed to produce the expected frequency response when tested in an anechoic chamber. Have you even actually seen an anechoic chamber??? Do you actually test the response of your drivers???...or just sit them on a bench and chuck a sine-wave through them and go "yeah, that's OK". When we produced tweeters for very demanding customers, such as the BBC and expensive Kef products, every single unit was listened and matched-into pairs by myself and my test equipment. If you have found a customer who's knowledge of audio equipment and the simple laws of physics is so poor that they think this particular driver is "cool"....then good for you.....I am just eager that viewers of this particular post , whom may be likewise rather impressionable by big numbers, do not leave with the impression that this unit is anything other than a gimmick. It will not be any "louder" than a unit with a magnet 1/4 of the size....one more time: a 10"cone will only displace so much air, no matter how much electromotive force applied. I don't like to see people waste money. Don't try to BS people and don't question the integrity and "real-world" experience of far wiser people than yourself, whom you have never met....and for your own PR, for heavens sake, don't do it in front of the world and potential customers.
EMF Audio
EMF Audio Month ago
@iseeolly It's clear you worked for them, but you didn't engineer for them, and have no real world experience with anything that isn't PA equipment. These drivers were built for an international customer a month ago, which means they aren't available to me.
iseeolly
iseeolly Month ago
@EMF Audio That driver will not be any louder than one with a 1/4 of the magnet, it is large just for the sake of it....all show, no more go.....neodymium magnets would ideally be the way to go...but then it wouldn't look so cool would it? I worked for one of the worlds largest speaker manufacturers, and yes I have hand built drivers and tweeters. I'm just worried that the comments section is full of very impressed people whom would seam to have no grasp of physics whatsoever. A 10" cone...be it with 30mm of travel, will only shift so much air....why not put an even bigger magnet on it, why stop here?....another good marketing ploy is to give it a model number that sounds impressive....ohh.. Sub47,000...(use plenty of noughts!). Would it be possible for you to publish a frequency response curve (half-space) and sensitivity for this driver? Good luck with the customer, I'm sure they will be happy with their good looking driver.
EMF Audio
EMF Audio Month ago
@iseeolly Right, you've SEEN them built. If you have a clean environment, you don't have to have the gap covered until the split second before the coil goes in. I know this because I've DONE the builds. I'm not in a giant dirty room with metal shavings flying everywhere. Even if there is dust in the gap, it will blow out. I tried to stray the customer from this specific build till explained exactly what he was doing with it and what he had already he was replacing. I built what was needed, I wouldn't build the wrong thing for the job.
iseeolly
iseeolly Month ago
@EMF Audio I worked in quality control for Celestion and Kef in the UK.....so yes, I've seen thousands of drivers built. I also worked as a freelance sound engineer for years...done loads of gigs for a little band called The Royal Philharmonic Orchestra, I've used sub-cabinets larger than my car. I get that you are giving your customer what they want....but is the customer always right?

EMF Audio
EMF Audio Month ago
It is normal for the dustcap to get warm. If it is too hot to touch that may be a problem. If you can touch the dustcap without burning your finger, it's below 130 degrees and that is normal. It sounds like you might be clipping the sub, which generates more heat. It may be possible to put a different coil in the sub (the entire thing would be rebuilt) but if you are clipping it, the same thing will happen.

Well, about the only thing can say is ... "You got SOME SKILLS there!" Now, I probably would use my old technique (Not that your's isn't great.) So what *I* generally do is see which tire stores around here are having a sale, make sure they've got them in stock, and then I just drive it in. This has the advantage of giving me time to grab a beer and sandwich, and that's usually done by the time I came back from my lunch. That, of course is quite important you know. Oh, almost forgot. I check the job out BEFORE I pay for it; the last shop seemed to forget to tighten the bolts and such and, while "amusing," it was a devil getting my car out of a wall when one of the bolts decided to just roll away. But it worked out in the end, although one tire did get away, and we couldn't find the darn thing...) Sorry, I couldn't resist. So lemme say it again, the job you did was amazing, truly amazing. Thanks for the video. ;)

Since you build speakers it would seem to make sense to have some rings to put on the surrounds for glueing rather than having to use dozens of clamps. I'm not a speaker guy, just something that popped into my mind when I saw you putting all those clamps on. Very cool video, interesting to see how it all comes together.
EMF Audio
EMF Audio Month ago
That's something I'd considered making, but ideally they'd be made from aluminum and it wouldn't be a simple ring, there would be some additional work to make them fit how I'd want them to and that means cutting down a big piece of billet. They'd be quite expensive, with multiples of them, in 3 different varieties per size for each basket we use. So to have enough for 2 subs at a time it would be 18 of them.

Thad ward
Thad ward Month ago
but why? Sound = moving air, smaller cone less air moving, even with ridiculous xmax. Also high xmax = higher distortion than moving the same amount of air with more surface area and less xmax. Also efficiency goes up with the increase in cone area and power requirement for the same output go down. But if this is going in a car then never mind.
EMF Audio
EMF Audio Month ago
This explains why your first statement is wrong. ruvid.net/video/video-ykPn0CpdrVQ.html Secondly, high xmax is higher distortion if you have a bad design. There are plenty of subs with more xmax than this that stay clean. That being said, this is for a car, we're a car audio company. 10's aren't used for PA applications because space isn't an issue, home has practical uses for 10" but not of this size because of power requirements.

If 10" spiders were used you might be right, but this has smaller spiders that limit the throw to right around the point where the limits of the surround are met.

Because it wasn't dry yet. You don't glue it together and instantly throw full power on it. Adhesives take hours to fully cure. The other option would be watching the video that came right after it though.

Today's theory of "heavier is better" is so ridiculously mislead. Obviously today's generation has no clue what little it took in the 90s to go well over 150 db, but to each their own. I personally don't care what people run or spend their money on, but this is just something I see as a novelty and useless waste of money. Nice video, build process was nice to see.

Something to consider, a 150 then is a 143 now on the same meter. You were also not doing at say, 30 hz, back then. That means you have to have over 4x the acoustic pressure to do the same thing then and now.
