Understanding klippel graphs and upfiring and down firing.

[shrub0]

I recently built an up firing omni speaker. I'm trying to make sense of klippel bl and kms symmety graphs. Looking at the plots is the slight sag of upfiring working to my advantage?

Actually since this is a 4" inch driver the calculated sag is only .035mm but I'd still like to know if upfiring or downfiring can help offset issues.

My first thought would be to question the symmetry of the motor, as to how much this will be an issue. Were you thinking along the same line?

Since the woofer is facing up I was thinking that there would be a little sag in the coil in direction. Just wondering if this helps or hinders distortion based on klippel graphs.
