PETTaLS Flat Panel Speaker Simulation Software

From the impedance curve, I wonder why PETaLLS shows peaks around 2k like if some modes are visible in the simulated impedance curve, not in the measured one but peaks are visible on both SPL curves...
Christian,
I'm not certain that I understand what you are saying/asking, but the measured impedance did show peaks around 2kHz. The first was really small, and the second a bit larger. The two peaks did appear at a bit lower frequency, and smaller peaks, in the measurement, than in Dave's revised hi res sim.

The link in Post #1 is still not the correct one. I used the link in Christian's Post #6 to download the latest version.
Eric, I think it would be good if Dave also has editing rights for Post #1 to update future links. It is as simple as asking a moderator to arrange that.
twocents,
Such little faith you have in me! Haha.
I think the link is correct now, at least it's the one Dave asked for. I was traveling for work all last week and couldn't do any editing except via my phone, which I'm not so good at. Meanwhile I did request for Dave to be given editing rights. No response just yet.
