I've seen comments like this. Trying to understand maybe with an example crossover what this means.
Are there any reference designs for 8831G, 8530K, etc. from Scanspeak that show how they expect the driver to get used?

Also, classic SS drivers have that tiltup above 800 Hz so that you can use a single pole in the crossover around 250 and not have to play as fancy an impedance control tricks to put a zero in the response to stop the BSC - hence the 800 Hz rise. It can simplify the crossover. BUT, one side effect is that the cone's first mode is at 800 Hz, creating a coloration. I used to use these SS drivers in the early 90's, but haven't for a long time- I find I prefer pistonic performance to beyond the crossover region- midrange is clearer.

Why the heck would you want the on-axis woofer response to go up 4-6db's, have the off-axis response drop like a rock from 2khz on, but have the on-axis response shelved high out to 5khz?
And then the Illuminator,

What is happening at 5khz on that driver?
