Default has anybody tried Bohlender Graebener Planar Transducers?

these things come in long length (some 48" long) and supposedly can go down to 150hz, might be suitable for dipole line arrays? Has anybody tried them?

the FR curve in the datasheet looks pretty flat as well.

The BG drivers are known for good sound. I have only heard the small tweeters but they sounded pretty good.

I'm using a pair of NEO3 tweeters in a sealed enclosure. They're quite good for the price! Can't vouch for the arrays.

I've used the 72 inch model. I use Magneplanar tympani panels as bass/midrange driver. Each BG is bolted between 2 panels - in the original tympani, the tweeter was on the outside (or inside depending on your tastes). Cross over set to 660 Hz I chose this as the half power point.

I've also built my own true ribbons to replace the BGs. The BGs sounded good, but don't have the same HF extension that true ribbons possess. I've posted pictures of my ribbons somewhere on this forum.
