Hello Toddalin
Happy Fathers Day
Not the entire range just the last octave 10-20K And if watch you own video you can see how the response 10-20K drops way off, almost off the scale, from on axis with or without your lense 4:28- 6:28 as an example.
Even on axis the last octave response 10-20K is down quite a bit not knowing what your scale is.
Like your lenses they look nice.

Okay,
Let’s look at JBLs own measurements of the 2307/2308.
Under magnification the last four plots are between -5 dB and -7 dB down at 30 degrees off axis. They are between -7 dB and -10 db down at 45 degrees off axis.
So above 10 khertz it’s got a dispersion of 60 degrees (ref -6 dB)
That is exactly why the slot radiator cuts in just below 10 khertz in the 4 way monitors.
The vertical dispersion narrows down to 30 degrees above 10 khertz (ref -6 dB) .
If time permits l will look at the effect of the lenses proximity on the off axis response of the 2405 (4345 baffle).
As a side note when l was using the 2344 bi radial l could always tell when the HF trim adjustment (above 10 khertz) was just right. Not enough and it sounded dull. Too much was too bright.
(I later sold them to Kent at Pass Labs after building my 4345 clones)
