605 time delay crossover

[Alien_Shore]

Don,
Here's my first attempt at measuring the woofer using the new zobel and your test chirp:



I'm a bit lost on how to compare the HF...when I isolated just the HF, the pulse intervals seem to line up to the LF pulses (when each is measured independently). I don't know how to discern the difference in the delay between the two...

Oh, and as far as testing the DATS rig, yes, I did that thoroughly using precision resistors and caps I have on hand. All those calibration tests were looking good.
