I noticed the same thing with the two way JBL L26 speaker. My ears said WAY bright at JBL's recommended "o" position. I also confirmed what you found with your analyzer on my L100's with my ears as well...kind of shouty at zero position and much better at -3.

I am wondering how anyone could really judge Jbl speakers with incorrect factory recommendations so far off. How many people had analyzers or at least trained ears to set them correctly in the 70's? Hah! Today anyone with a computer and a $50 measurement mic could have an ok analyzer but not back then but even today I can't get trained studio pro's to break out a measurement mic without twisting an arm!

Even more of a curiosity is how the factory arrived at those settings? Did one of the largest speaker companies in the world at the time not have any test equipment? mmmarketing people making engineering decisions?

The marketing department obviously axed the 5 cubic foot sealed box the
123A woofers need. That is understandable but not super hot tweeters and mids.
