@@HexiBase I think the problem is many brands just re-use already built subwoofers or „kits“ as in manufacturing term and they just rebrand those finished subs, without actually knowing the parameters or doing any research on it. Why put effort and money into research when there’s already a lot of stuff to choose from - same with class d car audio amps - a lot of brands use the same boards or very similar designs, as you can see in barevids amp repair videos.

@@practicalguy973 Sure there could be a change with break-in, but I'd rather find out that I should design an enclosure with a 5-7Hz lower resonant frequency and more moving energy before break-in, before I see an even lower resonant after break-in (meaning my design would have been even further off).

Break-in will shift specs a little. Fs will drop, Vas and Qms will go up... I've seen as much as 10% (I've probably measured over 1000 drivers)... However, if you model the same driver before and after break-in, in the same enclosure, the change is almost nothing. So, in the end it is usually not something to worry about. I do recommend loosening up the spider on brand new drivers before making your measurements. Just to break up the starch that is used on the spiders. The specs change a lot from temperature change. That is your real concern. The Qes increases as Re increases due to heat. Drivers are more efficient when they are cold and loose efficiency as they heat up... which causes them to require more power... which causes them to heat up more... and so on.

Small signal TS you measure with DATS (or 3USD equal equipment made by yourself) are not the best way to represent a woofer in a real world application. Some manufacturers might provide TS parameters measured using large signal, which suit the real world better. However in most cases it's just manufacturing differences between the batches

When asked, Precision Power would not provide TS parameters for any of the speakers. They told me that it was an internal document not to be shared with customers. Sad.

Hi! I bought the DATS V3 and have found it pretty useful. I discovered it can be used as a basic oscilloscope, but I am not quite sure if it is accurate. In oscilloscope mode you have to set the test tone output to minimum setting and then you can use the test leads for measuring whatever signal. I am unsure how much signal level the DATS can handle so I am a bit wary about using it that way.

By measuring the same drivers with version V2, all measurements are error-free and show identical values I sent an email to the manufacturer to know about this inadmissible error because it calls into question all other measured values ​​in other drivers and I don't like it at all because I wanted to switch to this new version but it turned out that I didn't get a better and more reliable device for this money I noticed one important difference that seems to contribute to the device making errors, and that is the speed of the test signal, which is slower in the V3 version, lasts longer sweep signal If someone can confirm this, let them try a device with low resonant frequency drivers that has a soft suspension, an error occurs with two of the same drivers.

I suppose some companies will write their ts parameters after break in. GR Research tested the same driver out of the box and after 50h of hard playtime and the fs was way lower for example. So one company they discussed with mentioned that the parameters they state are after a certain run in period. But of course, the numbers within should still match mathematical rules as explained.

I just wanted to add that if you run an impedance measurement on a driver in a ported enclosure you will end up with two peaks. The lowest point between the two peaks is the tuning frequency. It's especially useful for vents with many bends or irregular shaped ports (even tapered ports). Enclosure design software can't exactly account for airflow resistance due to things like corners, and that could shift tuning by quite a few Hz. However, it is low power... So you need to keep in mind that once the air really gets moving, and airflow is being restricted by the port, the tuning frequency will go lower (essentially that also means the port is too small, but is just how is has to be sometimes).

so does datyon audio use that on their own subs?

I plugged in my DATv3 to check the initial calibration and my headphone audio went to the DATv3 and speaker connected to it. LOL

V3 is twice as powerful as V2. That doesn't make a big difference with large, high power drivers. But it can drive smaller speaker pretty hard, the specs you get will be a little more "real world". I've even measured some drivers where I could see cone and frame resonances show up on the impedance curve that I never noticed with V2. I thought something was wrong at first, and then I realised it matched the frequency of a peak in the response (it took me a minute to figure out what was going on 🤔). It is even enough power to excite resonances in enclosures and ports, and that will show up as little ripples in the impedance measurements. So that is a nice upgrade. Also, the added accuracy is great for measuring caps, resistors, and inductors. Heck, I have mine mounted under my desk... that alone made it worth it to me, lol!

I’ve had my dats for about 2 weeks and I have yet to test a driver that’s reasonable close to its advertised specs. So much so that a basic taped pipe is both slightly out of tune but also designed based on incorrect parameters which dictate a false impression that now clearly is audible through the trench in the middle of the bandwidth and undesired symptoms of delay.... I then proceeded to rest everything I had, a majority from this huge multiple decades of popularity and following of ignorant(now no longer including myself) consumers. The two pioneer 10” subs I happened to test from the shelves of the garage were quite closely matching the published. Everything is fully broken in and in good working condition. Not much of a pioneer speaker buyer. Apparently mistaken and should note in closing Rockford Fosgate has klippel testing references yet did t remotely test properly on my new dats and there’s an enclosure the p3s were designed around erroneously and that’s fuct.

Sometimes no as big a difference as you would think, but yes I think it would be good to break it in, plus there is also a difference in what position you have the driver under test, so for example if the factory had it held vertical with very minimal surfaces around the driver compared to this example where the driver is horizontal with a table close to it and a little restriction of the vented pole, but with something big and heavy I can see the reason for doing horizontal even though not as accurate.

Here is a copy and paste of a reply I made above... Break-in will shift specs a little. Fs will drop, Vas and Qms will go up... I've seen as much as 10% (I've probably measured over 1000 drivers)... However, if you model the same driver before and after break-in, in the same enclosure, the change is almost nothing. So, in the end it is usually not something to worry about. I do recommend loosening up the spider on brand new drivers before making your measurements. Just to break up the starch that is used on the spiders. The specs change a lot from temperature change. That is your real concern. The Qes increases as Re increases due to heat. Drivers are more efficient when they are cold and loose efficiency as they heat up... which causes them to require more power... which causes them to heat up more... and so on.
