yerwelcome, so you added magnets to the sub while testing it for ts, instead of placeing it in an enclosure? why? i wonder if image dynaimcs will now start useing your drivers?

As you alluded, there are two ways to test drivers: 1) add mass to shift compliance; 2) load in a sealed box to shift compliance. From my technical contact: "We test with praxis, sine-sweep, at 2.83 Volts, and the data is within 2-3% of LMS data taken at 2.83 Volts, except that Praxis uses a more data-points and has a higher order better curve-fit, thus being slightly more repeatable and accurate. The new LEAP5 model is probably most accurate, but is very time-consuming."

So in short, we use this method 'cause it's practical!

Hi Mike,

"1) add mass to shift compliance;"

I'm sure it was just a typo, but adding mass shifts Fs.

In fact, both methods will shift resonance - but yes you are correct.

I could defend better once Mike makes me an authorized dealer so I can help him sell more of these beauties
