interesting new drivers from Radian

[gregbegland]

PE carries the Radian compression diaphragms, but doesn't seem to offer their other drivers. Sad, because these new models have me interested.

All apparently designed by Igor Levitsky, one of the leading planar/ribbon designers around.

Am I missing something? The only "circular ribbon" I saw in the first link were the words "circular ribbon".

And the LT2 in the second link looks suspiciously similar to a BG product.

Yep- the coaxes other than the one with the ribbon across it have the ribbons mounted to the rear.
Interesting,

Ahh, yes, now I see it.

I had always thought ribbons were inherently fragile, at least more so than the typical large format compression driver used in pro-audio. Then Peavey came out with the Versarray. I had read the system sounded really good, but wondered how those ribbon assemblies held up to abuse.

True ribbons, yes. Planars can be very durable and have been used successfully for years in high spl environments by companies such as Alcons Audio and SLS.

Incidentally, Igor designed the drivers for SLS way back in the day. I first met him at their booth at an AES convention about 15 years ago.

I am really curious to try the coax ribbons for some high spl cinema applications.

Don't forget Stage Accompany... where's thylantyr now I wonder?
HiVi had the Pro planars.

Lol, good old Thy. Loved those SA drivers that's for sure. I don't recall the Hi-Vi pro stuff.

Radian now have the matching waveguides listed. Things are getting more interesting.

PS, anyone got contact info for Igor Levitsky? I'd like to ask him some questions about these drivers.
