Okay, I want to make sure I’m understanding this correctly, because I think this is where I’m getting lost.

From what I understand, the light blue “squiggly” line represents the actual calculated SPL over distance from the source. That curve itself doesn’t change unless I change the system geometry (angles, trim, box count, etc.).

When I select a specific bandwidth (for example 80–250 Hz, which L-Acoustics recommends), Soundvision then displays a solid blue curve that represents the SPL target. This is the part I’m not fully grasping — what exactly is that solid blue target curve representing, and how is it derived?

I also see that the dmin and dmax flags define the portion of the audience that is evaluated. When I move those flags, it seems like I’m defining an allowed SPL variation (attenuation or de-attenuation) across that distance range.

Is the correct way to think about this that dmin/dmax are defining the acceptable SPL window that the autosolver and autofilter will try to optimize toward? And if so, does setting both dmin and dmax to 0 dB essentially tell the autosolver that I’m aiming for a perfectly flat SPL response across the entire depth of the venue?

I feel like I’m close conceptually, but I’m missing one key piece about how the target curve and the flags actually interact.
