Break in period for subs

We have other tools such as Klippel and RTA, but the most precise way to measure output at high intensity below 100hz is with Termlab. And serious competitors in SQ and SPL live by RTA and Termlab numbers and very often keep careful notes. It is telling that 20+ years of people competing with DD subs and none of them has recorded any testing data showing some significant gains happening from some break-in ritual or otherwise gaining over time without changing any other variables. This has to be the best kept secret since the Manhattan Project, possibly better because it has stayed secret longer.

Notice we're already getting into some light backpedaling here "well it doesn't hurt to be safe" and "it doesn't matter if we can't measure it, as long as I tell myself something sounds different".



The absence of evidence is not the evidence of absence, amirite?

That's the point. The mechanisms that humans have to perceive sound is very complex and well known to not be reliable. The parts of the brain that remember sounds are even less accurate. There's loads of scientific papers on the subject on humans' perception of sounds.

Burned out my little Dayton 8 inch yesterday while breaking it in (which is more just just a break in for my ears to see what a new sub is capable of). I was running it through my playlist of metal, classic rock and rap so I could get it moving fast on one song and play deep rap bass the next. I was so impressed at what this single 8 inch was doing on lows……and I fvcked it over hardcore. I just thought I would share the irony of burning out my sub during my usual break in ritual. Pulling the sub out of the box this morning to see the damage.
Man that Really Blows. Sorry to hear that. It happens, and Ive done it a few times myself

It happens man. I did that with some door speakers when I first put them in my Explorer, they were older. I was like "damn, these little door speakers have midbass." I got too carried away listening; I had the crossover too low and the music too loud and fried one during a series of hard punches lol. I heard it go 😭

I know what you're saying. Just because equipment is more accurate, that doesn't mean that ears aren't accurate enough. I'm very familiar on the ear and how it processes sound. I didn't graduate college before I got too sick, but I did make it through that part of my education in Audio Engineering Technologies, that I was going to Belmont University for.


IF I'M LISTENING TO MUSIC, MY EARS ARE THE ONLY THING THAT MATTERS, FART BOX MAN.


I trust my ears, and they've never let me down. The weather also changes, that changes sound, because it changes static atmosphere pressure (BAR), humidity, overall air density, which changes the speed of sound, which also changes the losses of the sound in the air. There's always something to say why something isn't right.

PWK has full vehicle 3D audio physics software, and occasionally something like that may even have a slip up in predicting outcomes.

I can hear when a sub is able to pick up notes after some play time that it couldn't before, and it was clearly due to play time and woofer stiffness. I feel like I've said this so many times. I'm sorry if you don't understand how EASY this is to hear. BUT, you might have to play lower than you do to be able to hear it, I'm not sure. I don't assume and judge everything about you, I just do it in sarcasm to your responses, since you understand how everybody hears, with your highly developed telepathy.

No doubt our minds trick us. I've tested the paragraph above with test tones. You'd have to be retarded not to be able to hear it. It's not woowoo, it's very simple, and it's happened enough where I've noticed. I care, because I've seen it happen. Many of my boxes can play well below 30 hz, some play well below 25 hz, some play below 20 hz. Ok? You're not doing that. Let's keep some relevance and context to our sarcastic judgements. You have a ton of knowledge, and I really don't disagree with you; you and I agree wayyyyyyy more than we disagree. I think we just come from two different basshead areas, which is fine, and I like it when people don't do the same thing as me. It keeps us all fresh and it's fun as hell. I need people like you doing SPL stuff and building subs and testing so I can learn whatever is found, from you, and others. I learn from everyone.

It's silly to say people can't hear stuff. You have zero way to prove that any single person isn't hearing what they think they're hearing. You can't prove it either way, if they are or aren't. So don't sit here and say I can hear what I've clearly heard from installing many systems and tuning them and I kept a whole list of tones on my phone to help with tuning people's systems. GTFOutta here with that stupid "you can't hear it stuff." It's asinine. And don't go acting like I say every sub needs a magic unicorn anal stretching ritual or something ridiculous like that. All it is: people just being careful with their volume when the sub is brand new, and especially if they're trying to dip low on the regular. It's just play time. No ritual. It's just being smart and careful, because you care about your equipment.

You could very easily prove that there is an audible difference with RTA or Termlab measurements. Prove and quantify in fact.

The issue isn't so much the ears (though they become pretty worthless with higher intensity and lower frequency which is felt rather than heard and outside the design of ears) it's the brain and memory areas we use that's the biggest wildcard. Again, this is incredibly well documented.

Nope, not that easy, don't have any of that. You're good at assumptions, that's how you have to reach some of your conclusions. If I had that equipment, and subs to test, then I would, but I don't, not here, and not now. I'd have to buy everything to prove that, and I'm not going to right now. The people who say they have the proof don't care to prove it, because they're making too much money running their successful businesses to stop and prove something that they already believe in, because they've tested it for themselves.

Go whine to the companies that suggest or require break in's or whatever. I already know the parts I need to know, when it comes to break in. This is all I've got. I'm sure there's some tests online arguing for break-in's, somewhere. I haven't looked. Like I say, why don't you email or call the companies that you disagree with and ask them for proof? I don't design these subs, I just use them. Go bark up their tree, I'm just another customer to most audio companies. I didn't make this situation. Asking them for proof that break in is needed would directly let you figure out whether or not they are full of BS or not, for yourself. Their opinion should probably be taken over my opinion, at least around the subject of break in time. I don't claim to be a break-in authority for companies, I just share what I've experienced, and I don't want to be a break-in middle man lol. If I disagree with a company, I'll say it. I disagree with Sundown's recommend port area for their E series, for example, at around 15 in^2 per cube. I just call it like I see it.

Go ask them about their magic ritual. They're the ones that made it up.

This is a non-sensical non argument vague appeal to authority. There is no engineering team that tests things without measuring relevant data and keeping scrupulous notes. In fact, if you read any of the links I provided you would see that in a couple cases it isn't even the engineers that come up with this "break in" stuff but the marketing/sales department.

I'm sure there's some tests online arguing for break-in's, somewhere.

And yet nobody can find them while I posted several links of measured data which reveal the truth about this subject.

No, it's not, you're assuming too much, as usual. I'm not saying it's RIGHT that they do that, but that's the truth dude. You're a clown who assumes to much, because you're aiming for a targeted goal, regardless of information I provide. My statements are always going to be seen through your judgemental lens.

Companies are too busy to tender to these types of questions, it seems. Get mad at me, not at them. I'm starting to think you have the charisma of a cactus.

The same companies that claim they have the data are the same companies that make break-in videos lol. That's why they make them, dude. Like, knock knock to your brain bro, they make the videos because they have tested it. Once again, you're gonna sit here an b*tch at me, the enclosure designer, but have you contacted any of these audio companies about their magic rituals yet? Have you? I have, and I bet you haven't. I don't make these subs.

Why don't you go make better subs and a better audio company than all of these people? You criticize a ton about things that actually really have nothing to do with me. Have fun being like that, my recommendations are manufacturer recommendations. I respect audio companies and people as individuals, which you seem to have a problem with, and you won't even put in the work to ask these companies you have problems with. YOU'RE the one with the problem, so if you want the data, go ask for it. My ears I trust, and that's all the data I need when I'm installing or tuning someone's system. I don't need measurements for sound, you know, because you can hear it.....lol
 
B2 audio recommends break in for their 1000w Rampage 8's. I'm doing a box for 3 of them right now.

Here's the manual, go all the way to the bottom, and it's in red:


THIS IS WHY I SAY FOLLOW MANUFACTURER: "Abuse of the unit is not covered by warranty." <- they say this reffering to overpowering subs during break in, it seems. So, don't f*ck your warranty up.
 
Here's the manual, go all the way to the bottom, and it's in red:
2" coil
1000W
2000W """peak"""
...warranty does not cover amplifier clipping or distortion (implying you can tell this is happening by looking at a broken woofer).

A very poor appeal to authority there, but do go ahead and take some SPL or RTA measurements when they're first mounted then changing nothing else, take some after 5 minutes of play, then take some a month or two from now and show us some audible change.

So many words and still not one single bit of objective data to support your claim.

Appeal to authority? You need your head checked dude. You keep talking to me disrespectful like that, you can go f*ck yourself. Absolutely no need to talk to me like that.
 
Just designed for a box another customer, this makes box design like 110 this year. Designed it for these subs. Pointing out a manual shouldn’t cause @hispls’s massive c*nt to bleed. That’s the only reason I saw this, *sshole, is because I’m designing a box for these subs. I shared it so other people could make their own choice. Why don’t you get off my d*ck?
 
@hispls

Seriously, why are you personally taking jabs at me for posting a manual for subs that I was designing for? Please explain why it’s ok to be so disrespectful to me, when I was simply posting a manual where the manufacturer recommends a break in? Why is that my fault? Please explain
