What happens when one sub is broken in and the other isn't? - Tech Stuff Tuesday 

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

What transmission?

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.

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.

Pay attention this week.

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.

The actual spider can tear away from the former also it wants to move but stiff spider restricting it then u have permature damage

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.

Moderate vol with bass heavy music a few days or so .

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.

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

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.

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

He's had 3 cars since then.

I havn’t had the ermahgerd since 2014 i think.

What's wrong with the website??

Basically.

If you're going for the highest metering possible, you do what the car wants.

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?

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.

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.

You typically hear it playing lower, better, after some break in. SPL gains are typically less than 2 dB, 1 dB is audible, barely.

😅😅😅

10's don't sell well.

Damn that sucks was planning on putting 20 10s in my back seat of my Malibu.

It's inevitable, need isn't a factor. A procedure to make it happen isn't needed.
