No AES papers, no KLIPPEL, just simple down-to-earth DIY measurements. Please?
Exactly. No JBL white-papers needed. Just simple measurements, that's all.

I remember to read ROAR thread and the design received many criticisms, the main one I remember was linked to the big dip close to upper band, a simple measurements may answer two questions:
1) The simulation can't represent what was build (bad accurancy) so the frequency responde in the real world is different.
2) If the real frequency response is good as claimed a reverse enginnering needs to be done in order to proper align the design with the simulation.

MMJ - an idea to further promote these creations - a 20 second video of those two lovely kitties (or equivalent) singing a Paraflex paraphrase of a "Paradox" from Gilbert & Sullivan's "Pirates of Penzance" = "a Paraflex - a Paraflex - a most intriguing/ingenious Paraflex -------- and Super Planar too"

I think they might despise me if i asked them to memorize a line like the one we see in the video from 1:23 to 2:11


I think this is a good example of how people had extra time on their hands back in 1929 .

Is it inappropriate to make jokes about the Great Depression?


Too soon?


Great old recording Freddi, thank you for that



Let us observe a moment of silence for those poor unfortunate souls who have their birthday on the 29th of February ..

regarding that somewhat long line (don't feed it to the kitties !) - perhaps singing-actors in 1879 had pretty good memories to handle such chore as film and edits not yet devised (how do they get through those 5 hour Wagner operas??? - prompter ?)

BP1Fan ,

Yes, they are the Birthday Challenged, and these birthday deficient people are called "Leapers" and they are rare, the probability of being born a "Leaper" is about 1 in 1461 .... ...

If the condition is not diagnosed and treated early on it then becomes more difficult to cure ... It is contagious, so in the past people who were afflicted with the disease were quarantined in communities known as "Leaper Colonies" ....
