Default BG RD40, RD50, RD75 distortion measurements?

Has anyone done THD measurements on the Bohlender Graebner RD series drivers?

After looking at the dismal distortion performance of most ribbons on the zaphaudio site, I am wondering if I couldnt find a better midrange than my RD40.

Default why?

Looking at that site, I see that the BG Neo's outperformed all the ribbons by a wide margin.... and the author also recommends the long BG's for line arrays.... sooooo

why do you think your RD-40's aren't good enough... there's nothing on that site that condemns them... in fact, indirectly, they are heralded.



my soon to me modified dipoles....

I've found a correlation between what tests good and what sounds good. In particular, low THD for me seems to be highly correlated with what I think sounds good.

If another driver measures better in THD in the 800-4000hz range I'd be inclined to ditch my RD40's.
