OK nevermind I just researched old threads and found one from 2018 that pretty much summed up exactly what I thought so no need reply on this when I get to my regular computer not my phone il figure out how to remove it all together thank you

RIP CA.com.
I have always broken in my brand new subs just by not going full tilt for a couple weeks to let the spiders loosen up. Only time I ever ripped a spider was on an HDC3 10 that I did not break in.

Depends on the sub.
Send me t/s parameters, I'll tell you how stiff it is

Some subs are so soft, it really doesn't matter.
Some subs like DD, some of these bigger box woofers, they have quite a break in process, and they get significantly louder over time. Example wise, the DD 9500's sometimes take a month or two of daily usage to actually break in. It's quite a massive difference.
So, some woofers it's very important to break in. If you don't, you can over-stress glued parts and the spider material itself. You can rip the spider, you can cause parts to become un-glued from their locations, like where the spider attaches to the spider landing on the basket. If that spider is super stiff and the sub has a strong motor, and you give it a ton of power, the spider stiffness can actually make the spider pull right off the basket. Like I say, it depends on the woofer.
Box design really helps the woofer to control itself. If your box allows your woofer to load well, you can generally be a little harder on it, because the box is controlling the cone movement, so it doesn't over-travel (xmax/xmech wise) before it softens up.

Bullshit all around. If your subs are breaking it's because they were poorly built and/or you over-powered them and not because you didn't perform some magic ritual.
The most dramatic shift in TS parameters on those super stiff suspensions happens in under an hour play time and then is very gradual eventually staying about the same. Shifts may or may not be favorable for gaining 10ths and they should prove to be well under 1dB (inaudible!). You're not gaining a deeb from 10-15% shift in Fs, Qts or Vas.
PM me and I can pass you some TS parameter data from some subs I built a few years ago, whenever I get my new parts in I can pull specs again before I scrap those softparts.

That's a pretty harsh way to talk about subwoofers to people. Glad you personality is shining through.
That's not BS man. I've literally worked for a DD dealer, heard it many times. These subs play music better over time. Some subs do have a break in time. It's not a magic ritual you d*ckhead, don't be like that.
So please, if you would, contact the company that held the world record for years and tell them that they are wrong about breaking in their own subwoofers:
Give Your Subwoofer a Break-In! - DD Audio
If you’re a frequenter of any online car audio forum or social media group, you’ve invariably run across folks talking about “Breaking In” their subwoofers, and we get daily calls from customers asking if they really need to do this, why they need to do this, and how to do it. Here at DD Audio […]

Where did I say anything about changing t/s parameters? It would help if you replied to what I actually typed, before basically insulting my intelligence.

Here I'll take a jab at you if you want it:
Your fart box tunings are so high that you don't even need to break a woofer in because you're playing high notes like any prefab can do.

We can discuss this topic like this or we can discuss facts. My statement was not about t/s parameters. I've never measured any subs before and after t/s parameters, personally. T/s are relative, you can spot a woofer with no break in time, but the t/s can still show the character of the woofer, regardless. I've only designed 1000 boxes, I have no idea what I'm talking about. I'm just pulling this out of my *** completely.
You aren't going to sit here and tell me break in time doesn't make many a sub play music better. That would be like saying grass isn't green.
I'll say it the normal non-hateful way: maybe you don't tune low enough to notice the difference. When a woofer breaks in, it plays lows better. Those of us who like lows, we really notice when a woofer breaks in, because over time, your subs will just play lower and lower.
Correct me if I'm wrong, but you aren't the type that goes around playing 25 hz on the streets, are you?

Because what happens is that people who aren't familiar with audio get their subs, and they try to beat the crap out of them immediately across a wide bandwidth. I've seen people blow subs from not letting them break in. I don't remember all facts of every system that did that, but a lot of times it's higher powered woofers that are really stiff. If you get a brand new woofer, especially a high powered one, and you immediately go try to drop below 30 hz on full tilt, that usually results in problems. That's one way we would try to keep inexperienced people from blowing their subs; you set the subsonic artificially high, and get them to come back in a few weeks or so and you can drop down that subsonic to where it ultimately should be.
Woofers can blow because the coil isn't moving enough to cool itself inside of the motor. So, when your woofer is really stiff, it basically doesn't move enough on the low notes, and that causes excessive heat buildup in the coil. Coil movement is essential to cooling, in specific situations. If the woofer was broken in, say in a box for it, the excursion on xxxx amount of watts will tend to be much greater as the woofer breaks in, especially on the low notes. Without that movement, the coil heats up a ton, unnecessarily and dangerously so, in some cases. But there's a ton of factors to that, it's very hard to blame any system failure specifically on one item; audio is complicated, many things can cause issues.
You've gotta let some of these woofers stretch out themselves, before you go super hard on them. I've just seen it happen like a playbook. You know when a customer is going to blow a new sub, you can just see it in their eyes that they are not going to listen about your advice about break in. We've had people literally come back an hour or two later with blown subs lol. These were good systems, good electrical, good boxes, good signal, etc. Maybe their songs were bad quality, but it probably had more to do with the volume knob.

Why couldn't parts be manufactured in a way that doesn't require breakin? Why don't manufacturers break in drivers/parts before sending them out the door? Sounds like that would eliminate a lot of warranty claims and improve their reputation.
