2 things I'd like to bring up: In the DATS manual, it has a section about margin of error. The differences you saw are within the tester's margin of error. You can test this by measuring the parameters of a woofer repeatedly and they will vary a percent or two on back to back tests because of margin of error. Also, the changes you saw are all within a few percent which in real life shows no audible difference. As you noticed based on the temperature, that has more of an affect on the parameters.

@lowriderbug 10 месяцев назад

i don't break in my subs but i also don't listen to them at full volume all the time so they naturally break in over time while i drive around then once i get to a show those subs are nice and loose and can easily survive a few 30s bursts at full power. 😎

@@MotoAtheist it all depends on the spider used by the company. On DD subs, they can be multiple times more stiff before break-in than they are afterwards. In fact they're so stiff out of the box that without going through a pneumatic press first, you can't put them in a sub. The strain of trying to move the spider will burn up the coil first. Even on powerhouse subs like the 9900 that can take 10k+ clamped after break-in

@MotoAtheist 10 месяцев назад

Breaking in a sub before use is the biggest laughable joke of all audio myths. It's even more comical when suggesting not to push the sub to it's RMS during this mythical break in. How is the material supposed to stretch and break in if it's not pushed to it's limits? Makes no sense at all. This is a myth that will never die, plain and simple, too many people truly believe they are accomplishing something that matters. No, no you aren't. Whatever you think you accomplished will never be heard by the human ear. Even SPL nuts saying they need to break subs in is ridiculous. Whatever the goal, the tiny bit of difference from a broken in sub shouldn't be your make it or break it tweak. If it is, they have already failed.

Then take sub B and just play it normally for some period of time, take another vote on how long to play it... week, two weeks. And then run your tests and see the difference. Not even sure how you would rate which one has the best outcome, based on what? It's all such nonsense anyway. I guess just compare the data and see which specs continue to match up.

@Pentenfi 10 месяцев назад

Very good video! I like your technical stuff the most. Just a little note here for those who wonder: You don't have to break in a sub when designing an enclosure. That's due to the fact that during break in, all parameters change in a way that keeps the simulated response almost the same. What is important though is that TS - parameters change quite a bit under high voice coil temperature and excursion. Then, indeed the response curve changes.

@DIYAudioGuy 10 месяцев назад

Yeah, I learned a lot from doing these tests.

breaking in really serves no purpose for most people. If you have a very high end sub with a super stiff suspension you may benefit from running a few free air sweeps but most consumer subs will break in during normal play. No need for special steps. The Fs will usually come down a bit as things loosen up and continues throughout the life of the sub until the suspension eventually craps out

Not a single company, not even DD Audio has anything about break in methods in their instructions.

Also, there is nothing special about DD Audio subs, they are just another brand with higher prices.

@chickenpotpie4045 8 месяцев назад

I've competed a couple times in the single 12" SPL category, did a 154.2 with a DD9512 back in the day. Anybody who tells you not to break in your subs and just run them hard straight out the box, is not your friend, that person is trying to sabotage you. Also, free air break in does almost nothing for a sub, the air mass of the enclosure is part of the suspension, you'll notice a second break in period when you put it in a box, where it'll get even louder over time, despite the first 'break in'. I have a blown up/ rattling Atomic APX 12 working hard a door stop as a constant reminder to gently break in subs over a long period of time. If you don't want to learn from our mistakes, go ahead and make your own, but if you don't want to waste $500+ burning up nice subs, 1/4 gain matched power for a month of daily use, then another month at half, then another month at 3/4, and finally a month later, gain matched to max. Yes, I spend THAT long of daily use, at least twice a day on the drive to and from work, before I ever run full power to it. Also, if you change the enclosure, it needs to break in again, not for as long, but it 100% needs some time to acclimatize to it's new enclosure, same for new amps. For the first week after I installed lithium batteries, I kept my headunit volume at half, and it was SO much louder than it was with just AGM batteries that I might be including that in my break in procedures moving forward. ANY significant change, give it some time to "settle" before you hit it hard. Or you know, do whatever you want, it's your money, waste it however you deem best. I'd personally rather my expensive toys last longer than one evening, but you do you.

Box volume is 100 liter and I want it to hit very low. But a way longer port would fit in de box. Now my question is: would it be better to use two 3 inch ports and make them longer?

I think with more motor strength and watts the more likely one is to tear a spider loose or break a glue seam. Most subs 1000 watts or less is not likely to break unless they are not built well. It's a motor force to soft parts ratio of sorts. With any product made, the more extreme the more likely a failure can happen. Take people with big builds for example. They are smoking amps and breaking subs all the time because they are extreme and that is part of it. So, DIY Audio Guy is correct that the average user does not need to worry with breaking in a sub.

Nonsense. You could never build a box, yes not even a horn, precise enough for a human ear to notice any difference at all between new and broken in.
