How to measure Thiele Small Parameters using your Sound Card 

I prefer to just hold the driver in the air with one hand, away from any surface, which can affect Fs and as a result everything else. If it's a large driver, I use a small rope threaded through its mounting holes to suspend it from a step ladder or chair.

Salutari si la multi ani!, ar fi foarte fain sa faci versiuni ale acestor videoclipuri si in limba romana, Marius, cred ca s-ar uita multa lume.

Amazing and such a timely tutorial on this , especially if the local indian brands are either not providing complete parameters or none at all TS params -> winISD -> box-design for low low freq sound - (trying iso-baric for smaller box)

WoW ! Just what I was looking for !

Nice video! A mixed option is to use REW & dats hardware. Allowing a better configuration (sweep duration, level) and the posibility to use the dual mass method ;)

Sd can also be calculated from cone diameter right in REW itself, in the TSP menu where you enter the values. There should be a small calculator icon.

I'm glad, that i purchased the DATS V3😅😅

Thank you.

Ótimo vídeo, consegui aferir os parâmetro TS dos meus auto falantes.

This is so cool that I just have build one, even though I don't have an immediate need. 😂 I already have all the parts on hand, and 1% tolerance resistors.

Thanks 🙏

I can use the line in of the sound card instead the microphone input? These are always stereo

I like the Dayton reference paper woofer

Obrigado Mario 👍🏻

Tried hard but all I saw was USB sound cards with mono microphone jacks. Do you have links/suggestions, please?

Hi! thanks for your Videos and tutorials. I have a 'rookie' question, not directly linked with T/S parameters mesurement. For the calibration of the internal sound card of a computer(desktop or lapto) in REW is it compulsory to do the calibration in short circuit (i.e in loop if I understood correctly) ? Could it be done with a Trrs cable ? I'm planning to begin with simple mesurements with a DA IMM6 on a computer. Thanks 😀

Would it be helpful to add a resistor between the mic and the one output wire?

My DATS V3 shows Re and Zmin same values. which should not be right? can you help me with that ? in REW Zmin in higher than Re ( ideally it should be). it also tells you Fmin and F3 in which speaker driver having lowest distortions. which is good :)

When measuring a frequency response curve, can I determine maximum and minimum limits for a pass or fail judgment?

Can we use this to test small headphone drivers? I t does need different rezistors?

Dayton Audio DATS V3 is well worth the investment.

Hi, I was trying to replicate all step by step and it fail to show up in windows sound panel. Now I have checked all wats wrong , and apearantley - on schematics you showed only three cables connected to stereo jack, while on video you have four cables going out from stereo jack! Please help to fix, Thanks

Hi, do you know how to measure how fast is speaker, especially bass, to compare old ones with small magnet with new ones with big magnet (or with open phase plug like your dayton)?

I have a 100w 4 om 6.5 sub with zero parameters on the internet. So to build a box i had found this method. My amp allows me to adjust volume and bass. Should i make an amplifier version and do i need to turn bass to the max or to the middle and then play with the volume knob to get right voltage?

based on my experience, slightly more powerful speakers, with lower qts, such a system misplaces the resonant frequency of the speaker about 10 hz higher. I wonder what it comes from?

Maybe you can say in the videos when you have a discount / promotion for your courses or in the description. I found out by mistake that you have a discount for the basic course.

How to know Le of voice coil?

Can i use rca input instead?

Hey your reference calibration resistor is a 10watt27ohm but all I have is a couple 1watt resistors. I can parallel a maximum of 5 will this be safe ?

What do you think of the Dayton reference drivers? Do they sound as good as they say?

Do you think it is possible to use an Audio Interface if my PC does not have the stereo input?

never looked into the DATS, as i dont have a need for it, but 130usd is way cheaper than i expected

i purchased das dv3, but i dont now how to measure high frekvency compresion drivers parameters. please have you any ecplanation

What usb soundcard with stereo mic input do you recomend? I can only find mono ones

Hello! Great video! Interested in Xmax measurements! Maximum Displacement! how to measure it! After all, this is an important parameter, and in some sports data it is missing!?

you could have calculated an enclosure using the three sets of parameters and compare volume and port length to see if the results are similar or vastly different.

Hi, I bought infinity alpha 121W 12 inch sub. RMS 250w Fs 33.5 Vas 68 Qts. 0.85 Qes 0.97 Owners manual suggest me to built ported volume of 1.6(45ltr) And port tuning of 36 Hz Is it possible to tune the port for 30 Hz is it meaningful to tune a ported box bellow Fs of the driver? Owners manual also given sealed volume of 40ltres. As the woofer has lower EBP and higher Qts i am going to built sealed one. But pls help me to resolve the doubt over ported box question. While trying softwares to resolve my doubt softweres don't show result for ported box. Because Qts exceeds Qtc of 0.7. Pls help me

Why did you private the old video? At least set it to unlisted or something. I was using it for reference

is there a DATS v2 or 3 teardown?? has some one Pics from the pcb/ chipset?? I bet my ass the dats youses a standart (soundcard) chipset with something like a lm386 at 5v to make .2v. If we know the chipset we can use the dats software. Or we can find a cheap usb sounddongle that we can mod with a lm386 and power over usb.

you get bulky bro from 3 years ago :D
