Hello all, looking to set up with subwoofer specific hardware for testing and measuring drivers and assembled cabs
I can use REW/ARTA on the software side but what about the hardware side of things. I believe a USB interface is needed. Will have to find a good portable one up to the task
Your opinions and experienced is valued more than google searches. I already purchased a Bheringer calibrated Mic and have a Yamaha MG12XU mixer with USB for non-mobile use. What's considered to be a proper setup in the chain of hardware?

Confused about mic config. Do I need a USB mic or is the Bheringer calibrated mic + USB interface ok? Will a very simple mixer like this work?

Randy,
Can you advise what you are planning to measure? And how?
That Yamaha mixer has a 48V phantom power for the Behringer mic, and a 2 in 2 out 24bit/highHz ADC and DAC via USB2.0 which you can connect to your PC.
Why not start with what you already have? Or are you looking for something more compact?

Making a bunch of different cabs for a pool of drivers to see what they are all about. Most of these drivers don't carry T/S specs, or they are a bit ambiguous. The DATS system is out of budget for now
The console is in a different room to my workbench and installed in a custom desk. It is also mains powered and chunky. Previously, it was stated that I would need to find wide open spaces to test subs. So, looking to get a portable rig together. I would not have any other use for a portable interface except for the minimum needed for testing in the empty car park. Ordered a cheap refurbished Dynabook Protégé X30W-J laptop that was high end 3 years ago. Hope it is still relevant today
.
Sorry, I have friends who travel with mixers larger than that. I didn't realise it was fixed.
If DATS is out of the budget, then @A4eaudio has a document or thread somewhere re: low cost audio interfaces and build-your-own T/S parameter test box. Hopefully he can chime in here.

I did a study on some mics and preamps but you don't really need to read it as the conclusion is a calibrated XLR mic and basic 2-in/2-out preamp is good enough for most speaker design.
I also showed how to build an impedance jig for a few dollars (instead of buying DATS) and how to measure impedance in REW.

Hey man, is this pretty much V3 of your jig but with the amp on board?

I assume this is to be used with ARTA or REW similarly to your jigs. What speaker measurements/tests can't be performed with this?
Also, I assume that the DATSv3 would be the most idiot proof but out of REW and ARTA, which automates calculations or leaves the least room for user error?
I think I will try jig three for now and save up for a DATSv3. Looks like a good system when the software and linearity test is considered and the component tester adds value
Here's something I posted last week in the ESL forum:
"The other chart is distortion. The two curves go down just as far as REW can take it in my house at that hour if nothing was playing. Not sure what it means exactly but "-60 dB" is 0.1% distortion showing up at the mic....
Hey, not bad for the headphone amp in my ancient laptop and an old cheap Behrenger mic mixer with phantom bias supply feeding the mic signal to a $20 Behringer DAC....not to mention my 1977 DW panels."
In other words, great results using gear that would be (incorrectly) considered junk by the golden-ear crowd. The shortcomings of speakers are monumentally bigger than any shortcomings of that test gear, including the headphone amp in my 2010 Mac laptop.

To clarify, Jig 3 isn't "mine" but another diyers mod of the jig Arta lays out in one of their application notes.
I don't know if I'd trust that AliExpress jig.
I have the DATS v3 and it is convenient. But I don't think I would buy it now that I have the jig.
I find REW's interface much easier to use than ARTA's. While ARTA can do some nice things, I find REW more idiot proof. I spent a decent amount of time doing measurements in ARTA and had something set incorrectly and didn't realize it until I went to use the data. With REW I would have detected my error right away. (I don't remember the exact details, it was a few years ago and I switched to REW and haven't opened ARTA since.)
I ended up ordering a DATSv3 today
Still to order a portable audio interface but leaning towards this as a future buy. I need a compact and reliable portable mixer and this ticks many boxes for a small three kid ensemble but is expensive to afford on top of the DATSv3

Also looking at this one just for speaker lab duty for now (home and portable)

What speaker tests would I not be able to perform with the DATSv3/interface and calibrated mic combo?
Also, with the DATSv3 hardware/software now in the tool kit, what tests remains to be covered by REW/ARTA via mic and line?
Thanks for the help guys
