Trinity 6 - 3 way coax ribbon drivers

I picked these up about a year ago with the intention to build some near-field monitors but have so many other projects on the go I can't realistically expect to use these.

The Trinity 6 is a really interesting driver because it not only has a circular ribbon tweeter but also a ring-radiator midrange which is the only such implementation I have seen. The woofer section is a 7" poly cone with the dustcap taken out for the mid-tweet array.

They do not have a built-in crossover; each driver section is accessible directly by the posts on the back of the driver allowing the designer to do what they want with the xover. My plan was to use them with a 3-way digital xover enabling the integration to be spot-on and response really smooth.

I don't remember what they cost but there is a German chap selling them on eBay for £150 each. I'm happy to sell the pair for that. So £150 the pair + £15 for UPS.

Here are the drivers, followed by an image of a commercial design using these drivers for inspiration.
