hello everyone .
is there an acoustic lens to be placed in front of the LF drivers?.
maybe doing this doesn't make sense (in fact they are usually applied to the HF drivers) since the low frequencies propagate in all directions, in this case the lens must concentrate and focus.
i wonder if there is an analogy with the optical lens (convex shape concentrates, concave shape diverges).
if it were possible to focus a portion of SPL i would like to try with karlson and hear what happens.
Thank you

Like this? Used I believe to match DI with waveguide at crossover

I believe the JBL-EON715 uses a version of slot loading to spread or diffuse the upper frequencies from the mid/bass driver.
The Kolster Brandes patent for slot loading dates back to 1947.
It sounds like arivel is suggesting converting sound from a point source into a planar wavefront.
Here is the optical analogy of how that would be done:
This can be done for high frequency sound waves by use of a path length refractor:
