I'm no expert but to my untrained eye, other than reducing the overall SPL I can't really see a difference in those sweeps.

Kelossus,
The fixed pad approach might be work looking at when time permits because it’s an overall reduction of the horn output.
This can be seen by reference to the left side db scale when comparing the purple and the pink curves.

Chiming in,I had the S3100 and I do understand why Kelossus wanted to pad the horn. Unfortunately that would muddle up the crossover region and caused the bass to be indistinct. The 1dB is JBL’s practice for fine adjustment only, and the speakers have been tuned to be correct at the crossover region. I would instead suggest experimenting with RC circuit to get a more pleasing slope for the horn.
Thank you
We will look at this more closely.
I'm thinking that this may be the better slope. You loose as much at the top end reducing fatigue, while retaining the detail through the upper midrange.
Hi Todd,
I am sure your thoughtful and generous contribution will be much appreciated.
