LSPCAD trouble

5th element · 14th March 2004, 04:22 PM

Ive been using LSPcad for a while and decided that I would follow IJ's walkthough so to speak of how to measure correctly in the ugly duckling project.

I have one problem I can get very good frequency response data but the phase is screwed. Ingemar says to make sure the simulations are accurate you need to compare the programs simulation for the combined drivers and the measured combination of the two. Then you compare the two and alter the Z coordinate until they match.

I cant get anthing to match.

And yes I am using windows of the right time etc. Just how are you supposed to get accurate phase data.
