Recently I got blown away by this Sica coax driver project and before committing to them for a longer period (probably up to 12 months max 
) I wanted to take a look around for other optional candidates
I came across with these two Radian ribbon coax drivers:
1. https://radianaudio.com/collections...ts/6crf5130-6-5-coaxial-with-planar-ribbon-hf
2. https://radianaudio.com/collections...6-5-coaxial-round-frame-with-planar-ribbon-hf
They are way more expensive compared to the Sicas but they are also bigger + they have a ribbon tweeter (those got me intrigued since my Adam Audio T5V project)
The great thing (for me, subjectively) about the Sica drivers is that they have the same superb holographic sound stage of full range drivers combined with more details in the treble. But less detail vs. the T5V's ribbon tweeter
So when I found these Radian drivers I was like: Why not combine best of both worlds?
They seem to have pretty good measurements (compared to the fact that they are coax drivers) - although the directivity curves of the Sicas look better in my opinion at least
I would really appreciate if anybody with real-life experience could share any thoughts
(or even without experience, just for the sake of the argument)
Thank you, appreciated
