Brad, I have a few drivers I think people might be interested in. I have the SB Acoustics 4" midrange buyout from PE, the Arylic AMT tweeter, that 5" Dynavox we already discussed, and the new version 6.5" Dynavox that I think would be fun to compare to the vintage version you already tested. Interested?
Interesting comparison. So if you mounted them diagonally, would you then get a set of compromise plots with curves roughly half way between the H and V curves?
Fantastic/eye-opening data!
Seems the less steep wave guide [WG] created by the horizontal cone shape/orientation really does reduce directivity at lower frequencies than the steeper/narrower WG shape of the vertical orientation. And these sweeps are done at 1 meters' distance, correct?
Great information as I am finishing up some test boxes with 6X9's now . . . and it looks like reducing ceiling/floor reflections using 6X9's is a viable option too.

Faital pro 8fe200-8
Kasun 2102x tweeter.
JF-ECO608-08
This looks great
Interesting stuff to test.
It will be interesting to see for the 6x9er what, if any difference through its usable range, for the off center curves, horizontal vs vertical
I will measure it both ways
Its a very nice driver. Makes a very good large form factor midrange.
GRS 5SBM-8
Without the 18uF cap it died on the bottom end.

Yes Sir.
I should be able to drop them off today after work, would be around 5ish if that is alright.
I’ll be here.

Brad - thanks for putting the effort into all this testing and publishing!!
No problem. I like doing it. Hoping to find a diamond in the rough.
Audison AP6.5P
One of the better car audio drivers I’ve tested.
Audison AP6.5
Audison AP690
0-75deg. Mounted in vertical position.
Audison AP690
Mounted in horizontal position.
Comparison
Looks like a good choice for a woofer in a slim 3-way, provided you like the oblong visual.
Hogtunes 690
I used these in The Monster build a few years ago.
Interesting- thanks for the vert vs horizontal measurement comps
