Man I’ve been WAITING for a new viddy. Thanks for making these. They are very helpful and you make It all easier to understand.
Love the attitude 😆 love the vids! See you next week.
"you just put it in the box! and you can play it! its fine!"
killed me hahah
I bought one of my subs one month, and installed it, and purchased the second one the next month, after watching this video, I did just what he said, installed it and played it. I never pussy footed around with it, or went easy on the subs, the "break in" was me using them how they were intended to be used and I've had no problems whatsoever
I drive a fairly small car an old Datsun and I used to break in my Subs. I would slowly push them and push them until they would start to stink... a little bit and then I would turn the sound way down... not off. But let them cool down and repeat. After about a week of doing that they wouldn't stink anymore and you could turn them up for a couple hours at a time.
I just installed 2x12" Ground zero subwoofers in my home theather. Recommended power is 350w RMS per subwoofer, im pushing probably around 400w per sub from my home theather subwoofer amp. the subs are single 4ohm coil so ive wired em down to 2ohm. they bang
Ya tec stuff Tuesday glad your back.
I've been buying subs since 1993 and I have never ever broken in a sub. I buy my subs, install and go full blast.
Great video man!
Pfff me too. Ive never even heard of breaking in subs. I over power and run them hard without clipping. Never had a problem with good tuned boxes.
@@joelthomas79 the glue on my kenwood 12’s came off and I got them tuned at a highly rated shop. I played them extremely hard first two days and now I gotta replace them ;(
@@airuzair2424 lesson learned? don’t buy kenwoods again
@@kcin2der18 are they known for being shitty? what about kickers
@@airuzair2424 shitty, just replaced my L7s with audio pipes
That's a crv it's going to always be loud😁😁I love how you stated that and what you said after that. Yes other cars like a 2 door blazer gets loud as well but long as you test everything in the same car it don't matter.
Appreciate all the videos I learn something in all of them!
"Put it in a box its fine!" man I loved that. Cool vid
This video is awesome!
You had me intrigued from the beginning knowing what the final result would be.
The Ω & power drop was new to me.
But when I got to seven minutes into it you made me lol.
🔉🔉😎👍🍷
I had one 4+4 sub on a 1ohm stable amp for like 6 months. I wanted to drop it down to 1ohm to unleash the beast so i added a second new one, when the first was more than broken in. 3 weeks later, boom, transmission bit the dust. Coincidence? I doubt it.
What transmission?
"Put it in. Play it. Enjoy it."
Im inspired. Thanks.
wish I found this channel a while ago love the crx
I've always wanted a CRX. Good stuff.
Does this theory hold true when 2 separate amps powering 2 subs in same chamber not strapped ?
I like the style of this video 👍. And of course the info
Awesome VID!!!
2 questions
1) What happens if you have 2 different subs in the same box sharing 1 amp? Say 1 lowballer 12 and 1 SA 12. Both dual 4 ohm wired to a final 1 ohm load.
2) What happens if you have 2 different amps powering subs sharing the same box? So say you have 4 lowballers and 2 of them are wired to a 1k amp and 2 of them are wired to a 2k amp? Can you just lower the gain on the 2k to keep it somewhat even?
Keep up the good content.
1) You shouldn't do it, it's not ideal, and in some cases it could cause a sub to be damaged. In your specific example it would play just fine, just may not perform as optimal as it could with matching.
2) Refer to answer 1.
Can you post a video up on a dual common chamber with a slot port.
The port needs to be closer to one woofer.
Not necessarily.
I treat a subwoofer the same as piston in an engine..
What I'm trying to prove is that one woofer will age faster in such configuration hence we see one woofer unload faster than the other.
Look forward to the musical versions of the V2
Is it ever to late to break subs in afther blasting it for 2 days ?
Good job guys. Now shows some amp stuff. Lol I have a Hifonics 1500. Mono I have it at .5 ohm witch it's not rated for but it's working for now. Maybe you can do something with ohm loads
th-cam.com/video/-l2P47QeytI/w-d-xo.html
What are the positive and negative of having higher and lower FS?
It all depends on the application. In this particular application, the installation performs best with a higher Fs. For a musical application you would want it to be much much lower Fs. It's all relative to the bandwidth being played.
Damn i have a sub that is broken in and one that was brand new and i slinkied the new one instantly on clean power too less than rated rms i though this video was gonna have something to do with that, i guess i did just get a dud coil. It was a resilient sounds subwoofer too.. 😭
I had a convo with an installer buddy today about breaking in and i asked him if its a myth or true he was adamant on breaking in properly cuz he says if u pump the volume on a new stuff suspension sub right away then the suspension cant handle it and cant break since its so stiff when new. Ive never had an issue and ive ran super stiff subs before but i never babied them for the first 1 to 2 weeks..i just ripped on them right away
He should watch this th-cam.com/video/awwhaY65nAg/w-d-xo.html
i had one sub for a year, added second sub that had minimal breakin. no problems, been 2 years.
Crank that sh*t up ☢️ BANG
Ty...so what's a good time limit to break in a sub round about?
th-cam.com/video/awwhaY65nAg/w-d-xo.html
Moderate vol with bass heavy music a few days or so .
Why would u not put a charger on the battery's ?
I wish u would do a lowballer pre order.
Pay attention this week.
If I had a 3000.1 amp and set it around 1500w on music would it be more efficient then having a 1500.1 set to 1500 I know it's stupid to ask but literally anyone I ask can't answer my question with facts I also think having a amp bigger then what I need would help avoid a little clipping daily
Amps don't put out a specified power amount, it is dynamic. So, a better way to look at it is set the amp to not exceed 1,500 watts under any condition. Now, that being said, if the 3,000 watt amp is 90% efficient and the 1,500 watt amp is 90% efficient then no, it won't be more efficient. It takes the same amount of power to make 1,500 watts. As far as clipping goes, if the 1,500 can make 1,500 watts without clipping then that's that. If it can't, then yes you'd avoid clipping by dialing back a bigger amp.
I did the same thing. 1 got a 18 then got another 18 in the same box a year later.
Does Tony still use the ermahgerd 18?
He's had 3 cars since then.
I havn’t had the ermahgerd since 2014 i think.
Are you going to upgrade website.
What's wrong with the website??
(Without bashing another brand because that always makes the bashing brand look bad) Why does Skar suggest, if not demand breaking in their subs or risk voiding their warranty?
My theory on manufacturers that suggest that falls into one of two categories. They either want an easy way out of not covering one (they could ask if you broke it in using their specific method and if you didn't adhere to it 100% then it's not covered, even a year later) or they want you to never play it hard enough to break it till it's out of warranty and it's not their problem.
Hey everyone knows a broken in sub plays lower and loosens up the spiders and break in means breaks the tiny fibers that are short on the spider and don't stretch far enough they just rip and I'm talking single strands of fibers not actual tears in the spider
The actual spider can tear away from the former also it wants to move but stiff spider restricting it then u have permature damage
All i can see are just straight proven facts. I' learning a lot even if i'm not a proper basshead
Great video as always boss man. Them subs look sexy
If I were a popular TH-cam channel, I would outsource (pay someone) to read all the comments and possibly respond to basic ones but send me links to all the ones that need a professional answer so that I wouldn't have to read the BS ones that will only piss me off.
Lol did I help you with this video idea? I have 2 EMF Banhammer 15"s. One of em I fixed the top plate and reconed.
The idea has been an ongoing thing for years, I just happened to have the opportunity with 2 brand new subs where I broke one in to get specs and both were going in a car.
@@EMFAudio interesting results nonetheless
Put that thang in the box and crank that bass knob up and break it off. 🥺💪👺
Some companies recommend that u do break in the sub a bit to loosen up the suspension and I agree with them as stated before...but to say it not needed as the sub will break in over time....is a reckless statement. Some people full tilt out the box....stiff suspension heat up the sub faster than loose suspension on the same amount of power. Also mixing a new with an old sub in a share compartment will have issues as one sub would not be able to cool as efficiently as the other....
You should watch more of my videos, where I prove all of that wrong. Also, you know what the sub not moving much from not turning it up is doing? NOT breaking it in. The amount the sub moves not broken in vs broken in isn't effecting cooling, and the more you push it, the faster it gets broken in. If you paid attention, it was less than 20 burps to get the other sub broken in which was REALLY stiff. That's almost like playing it wide open for 1 minute to get them to the same amount of stiffness. If the sub won't take rated power for 1 minute while breaking in, is it a sub worth having?
@@EMFAudio I see ur point but its dont take away from the fact that at 200w a new sub is moving less than a sub that is broken it at the same frequency. If we are doing spl that's ok but on music things start to heat up. Point I'm making is it would take more that 1 minutes to break in any sub with a sub that have been playing for months. Your next video u should be to prove me wrong Is to play a sweep on a new sub and an old broken in one and measure the temperature...i would say start the test at about 300w per sub some 12" should be a good option. I can tell u now the old sub would be cooler than the new sub over a longer period of time, and that's at low power now imagine pushing 2k per sub.
@@EMFAudio my point here is not to say all sub should be broken in before played but if u need ur sub to be optimal u should give it some break in time. Sub get stinky when push hard out the box rated power or not as some would assume it's over power or ur amplifier clipping....test has shown lack of movement has made subwoofer heat up. When broken it properly its takes on alot more power and dissipates heat more efficiently.
@@dwaynegentle What you're describing is heat cycling the coating on the coil, it has nothing to do with cooling. If having some break in period was critical to a sub not failing, why would I tell every customer (WITH US BEING A MANUFACTURER) to just play it normally, when I'd have to warranty any failures? It's because they won't fail from that. Yes it cools better when it's moving, but if it's not moving, you aren't breaking it in so it doesn't matter how much power is on it.
@@EMFAudioi respect your opinion and recommendation as a manufacture, but as a user and a system builder i can tell u what i observe and recommend in the field. . but it would be great to do a sweep say 80hz to 20hz and lets see which sub fail first...using rated power. i recommend using your subs to do the test. here in the Caribbean we play for hours also we demo for hours, reliability is key to purchasing subs. i honestly haven't tried ur subs, but i sure will after it has been proven to be reliable under rated power without having to be broken in. 1 to 5 minute burp don't prove reliability, dissipating that heat built during an hour long play does
I got 4 8’s and they don’t sound as good as my buddys do you think it’s because they aren’t broke in yet?
It might be your box design
If you design and make a diy box (there are plenty of tutorials on youtube using free software like winisd and making it using basic tools) you can get way more output. There are a few things that you'll need. The winisd program on your pc, basic tools like a electric saw, a drill and ofc the materials if you have the tools you can probably make a diy box that sounds 10x better then your current box for like 50 bucks
In short:
Your subwoofer box is probably more important then which brand of 8 inch subwoofer you bought. So Your box should be designed for your subwoofer and not any 8 inch subwoofer.
I designed a 6.5 inch subwoofer box for a dd506d (2 ohms) the design software says it will play down to 20hz but i havent made it yet but when i have ill update you
@@troybakker7628 i got them sounding good now my 12v wire was bad
@@sirdir5004 oh i see. But if youre looking for better or deeper bass a new box can always help
Hexibase has a video of a 3d printed box for a single 6,5 inch sub that made 136db in a spl test
The box that i am planning on building has some inspiration from it but ill use it in my home instead of car
@@troybakker7628 Thats sweet that’ll sound good I was trying to decide if I wanted to install an equalizer because I already have an epicenter do you think it’s worth it
@@sirdir5004 idk man i dont have a lot of experience with car audio since i never has a car or even my drivers license and this wi be my first subwoofer box build that I'll also use for a school project
But whats the reason you want to install a equalizer? A uneven bass response or sonething else?
Are they SMD?
no, better
@@maincharacter2677 😅
They won't yell at you and threaten your life for listening to another speaker.
@@EMFAudio 😄👍 Thank you for the information on the video.
58 is crazy high. I want a comp that is 45 or below
If you're going for the highest metering possible, you do what the car wants.
2:18 🤣🤣
I didn’t pause it LOL
Goddamn Carol Baskins broke my sub
Anyone else notice the blue tape covering the "Sundown" Audio logo on the box in the background? Lol
I'm wondering what your point is? EMF Audio is or has been an official Sundown Audio supplier but this video has nothing to do with Sundown.
@@lowhertzhighspl WAS a Sundown dealer, for 11 years.
@@EMFAudio Was?
@@EMFAudio what happened? Why r u no longer a sundown dealer? I have a feeling i know why..it doesnt have to do with the beef with meade is it?
@@akuma4u I'll be posting an update video probably tomorrow with a little info, the in depth explanation will come when the time is right. It has to do with 1 person that isn't him.
Thank you for addressing the breakin Karens. This is so ridiculous it is embarrassing.
Make a T shirt that says “Put it in the BOX! PLAY IT! ITS FINE!”
If u cant hear a difference...y does ppl keep saying its gets much louder after a sub broken in...????
You typically hear it playing lower, better, after some break in. SPL gains are typically less than 2 dB, 1 dB is audible, barely.
😅😅😅
I just reconed one myself and it sounds like straight garbage with one broken in.
What my crx does with 2 12s.😀
With 2,000 watts, legal?
Unfortunately, didn't clamp it for actual wattage.
Using 4 e-audio e3000d and a very broken group 31 battery.
Pair of apx's with dual. 7ohm
@@robv.o.1777 So not what your CRX does with 2 12's.
So basically what your saying is rule number 1 don't clip your subs to death watch what you do and life will go on lol
Basically.
Build then in 10"
10's don't sell well.
Damn that sucks was planning on putting 20 10s in my back seat of my Malibu.
are we not friendly with Sundown anymore ?.......
Do not play a new sub full blast out the box ... your spider is stiff af and restricting coil movement ...i u push too hard u may prematurely tear the spider away from the coil former and later down the road as u enjoy the sub ....it full tears because of how u treat it from new also u wont have full xmax which hinders the movement or travel of the cone which in turn hampers the cooling effect trust a sound guy with knowledge ..dont mind misleading info ...good subs arent cheap care your babies thank you
Hey mister EMF guy where's the new videos.... I need some new to watch Sir....😂 Thanks
Break in exists. It’s just not needed
It's inevitable, need isn't a factor. A procedure to make it happen isn't needed.
