Yea, there is no money in supporting old product. Got to push the new stuff.

I have the original DATS and it’s still in use daily. Mine was a simple dongle with test leads. Excellent and most certainly essential piece of kit. It has its faults though such as not having an option for testing an inductors value at industry standard 1khz. You simply read iff the impedance value at your chosen crossover point and calculate inductance. T&s testing can be hit and miss, especially using added mass method. All things considered it’s essential if designing speakers and crossover networks as files can be exported into cad packages to combine impedance and frequency response to derive filter designs.

That's a good question about the port resonance. I'll have to see if I can figure that out!

An important thing to look out for when doing the t/s measurement is the smoothness of the impedance peak around resonance. If it's not smooth, something nearby might be affecting the driver, which results in not only the impedance curve being affected, but also the measured t/s parameters may turn out to be inaccurate. To avoid this happening with woofers. I usually just hold them out (if I can!) at arm's length when doing the measurement.

Just a quick note, inductors don't burn up power when in a typical crossover. Resistance is increased in HF signals, so the signal is more likely to go to another source, such as a tweeter and not lost as heat. You know, path of least resistance.

Also, every drive unit made uses voice coils which all have a rising impedance with frequency so have an equivalent inductance. Passive crossovers lose very small amounts of power in inductor dcr and esr of caps as well as through heat loss in resistors but in general, it’s not why active is “better”. That is more down to output impedance of an ideal voltage source driving a speaker being zero ohms. It never is but in passive networks the dcr of the BASS inductor which handles most current (lowest impedance as it’s at lowest frequency) is ADDITIVE to output impedance of driving amplifier and since the only thing determining damping factor is the ratio of speaker voicecoil imoedance to output impedance passive will generally have poorer damping in the bass= more out of band resonance. The answer is simple. Use laminated steel core bass inductors and low output impedance amps. Too many badly advised people being recommended set amps by numpty reviewers!

awesome videos, i have a question, lets say you made an enclosure with the aid of WINISD, you aimed at a ported 30hz FS, but once you test it with DATS you come up with 22hz....what would be the issue or what to check ? can i just shave off the tube ports up until i get the desired FS ? thanks !!

What if you are measuring a 2 , 3 or MTM speaker performance? Do you hook up the clips to the speaker terminals jumped together ? Or if it is capable of biwiring you do the tweeter and bass separately ?

TS params change over time also even after a break in. I wonder if the manufactures TS params would be close over the life of the driver given the average of changing values. In car audio the change must be fairly large. Think of how Vas changes in a 100F temperature vs 40F.

I hope you see this after being posted a year after you released this... I have 6.5 DD 1506 supertuned woofers. I hooked my Dats V3 up and followed the instructions just as I always have on all my other builds. I calibrated both the leads and the impedance. I then ran the free air sweep. Then, I added weight to run the VAS sweep. I started out with a beanbag, got a error saying not enough weight 25% less than the FE. So I added more weight. Keep getting the same error. I went all the way up to 10 lbs and then even 25lbs. No, it didnt bottom out the sub as these things are beasts. But even with that weight, it still gives me that error. Im at a loss.

You want it to move the FS down by 25% (eg: FS is 40hz so 25% is 10hz meaning 30hz is your target or thereabouts on the sweep). Once you're close then clear that and rerun original sweet without added mass and then with the added mass required and it should punch out a result.
