Same here I’m running 6 dc level 6 18s with LR surrounds 1.4 ohms each wired to .97 on each of my crescendo 17ks. I been thru 3 sets of recones with clean power over the last 6 years you can go full tilt if you want to and almost cough up 1900 bucks in recones if you want to let them break in 🤣

Tip: break in your subs (free air) in pairs with 1 sub wired inverse polarity. That will virtually eliminate any noise from your overnight break in period.

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.

Great video and layout of detail!

Good Job Jonas.

When you mention filters I thought of hz. When breaking in a sub, does frequency response change after breaking in the sub ?

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.

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.

Guess I'm not your friend, oh well I'll live. Because break in methods are not needed, everything you just said is nonsense.

Some manufacturers break them in for two hours before publishing the TS parameters, i noticed a significant drop in Free Air Resonance (FS) after breaking them in. I think I will do a video about that 😃

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. 😎

Hi DIYAudioGuy, I'm boulding my first subwoofer box for a 250 watt rms 10 inch sub. I've ordered a 3 inch round port and have calculated with winisd that it should be 7,8 inch in length. 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? Or is one short one just fine?

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. If a break in method was required, these companies would absolutely have it in their manuals to cover their liability. Also, there is nothing special about DD Audio subs, they are just another brand with higher prices.

I read a study that showed the woofer parameters after break in will return close to the new never used values after the speaker sits unused for a few months. So break in is really a temporary state unless you keep using the driver all the time. I have not verified this myself, but it would be easy to do. It just takes some time.

So, yup - if you want a more realistic response measurement.

​​@@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

Running full RMS straight out of the box is never a problem, not even for the sacred DD Audio subs.

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.
