They look good, especially considering that you're using a very expanded vertical scale. Everything seems to go south below 600hz though
If I get a lot of variation in my pair of slims, Ill probably be sending them back. Sadly, my pair of BG Neo 10's had variations that were just too hard to live with(I may have damaged one). My BG neo 3's are fine though. If need be, I can take these up to 800hz with an 8th. I could live with that if it means better consistency
I damaged a few of my first set with too many rounds of solder/desolder. Units developed quiet wide variations btw themselves after originally being almost identical. I'm an expert level solder jockey too, so I was surprised, but when I called BG and talked with Chris Brunhaver, he explained how easy it was to deform the diaphragm material with too much heat. On the second set, I only ever used crimp on terminals to attach the speaker wires and the units have remained very consistent freq response over about 5 years now.

Word to wise. Using any of the planar drivers, DO NOT SOLDER.

Chris is now with PS Audio and working on revisions of their forthcoming (any century now) speaker line. Current versions are using a modified version of the Neo10/Neo3 coaxial design like in the BG Z62 center channel.

I've been following Chris's work with PS Audio for, like you said, a century now.

Have not listened, but tested two samples. big hd peak at 1.5khz, so using it as a mid was out of the question. As a tweeter crossed at or above 2k with a relatively steep slope would probably work well though, especially for the price. I was only interested in it's application as a mid, and who knows, it may still sound great in that configuration, but the 1.5khz hd made it a nonstarter for me

that's a shame - I too am interested in an application between around 800hz and 2-3khz instead of a Scanspeak 10F.

The original BG NEO8-PDRs kill it as long as you stay above 600-700Hz. Both samples were almost identical. Midrange performance from a simple harmonic distortion perspective is fantastic.

Most disappointed in the Radian, but it's still totally acceptable if you consider most of it's range is still below -40dB down or under 1%. Even some of the other drivers that look like they have a bad spike in the upper midrange are still at least -40dB, so overall pretty usable.

The Slim 8 is the worse of the bunch, as expected, with the highest levels below 1KHz. But used as a line array of tweeters, they sure are a steal.

nice measurements studiotech
I was specially interested in slim8 from grs, since I used it
here are some data I got, post #99:
viral projects, sort of
originally I wanted to use slim8 from 900Hz to 10kHz, then foster planar on top
however, distortion of slim8 was higher than I expected, not that it would sound bad or anything.
so I started raising the crossover frequency, to 1kHz, then to 1.2kHz, and it got better

Latest and hopefully final version of PS Audio Fr-30 released. Still a 10" Neo-10 style driver for mids.

They look beautiful. First glimpse reminds me of the Devialet Bluetooth speaker... you think function couldn't keep up with the form. Aesthetically you're not sure what to expect from them, but can only assume they'll deliver some great sounds.

I liked the comment "with as little as 100watts" like everyone has power on tap or something. Then again, having more power has always been a good thing IME.
