No,but it is going to be.actually I'm a friend of Salas,the speakers are mine,but I have not built the cabinets all these years.the project was forgotten but now is on again.i promise pictures from the building process.
Well,after 17 years, finally the project completed.it was a lot of time,I know,but finally the aluminum bliss got very nice cabinets,and a first order crossover.it sounds different than my other speakers,and actually different than any other speakers I have ever heard.the transparency must be heard to be believed.

Were little closer in the conceptual drawing. With four degrees back tilt too. It materialized so many years later, his cabinet guy could now make it CNC multi-faceted so they changed things like height and driver centers enough. But kept the bass volume original. I was told they crossed at about four hundred Hz first order with thick Mundorf air coil and Clarity cap.
I went to listen for a little. They look stunning in real life and replay much information with characteristic ease. Bass is firm. Nice to see an old project being finished.
This one as finalized has 3 degrees inclination at the Jordan unit which stands at 892mm height including small rubber feet. The speaker as a whole stands 1040mm tall at the back and 980mm at the front. Slanting for some asymmetry.
50 litres total volume for the 8" Alcone woofer and the 3 litres section for the 2.36" spider-less Jordan. Both types are long obsolete. Between their centres there's 290mm distance. That is about λ/3 for the told 400Hz* crossover frequency.
*Later on I measured the impedance rather showing 300Hz is the crossover frequency they ended up with.

Try not more than 150 hz if the Jordan can permitt that low cut-off.
Curious why you not chosen the SB23NAC with its ribs ? Very smooth driver (though still suffer from early break-ups... look at H5 too)

-SB Acoustics did not exist in 2006 when those drivers were bought. Post#1 is that old.
-This particular Jordan can't follow the Alcone 100W RMS woofer at 150Hz crossover. It would soon get damaged. Has no spider. Little closed box air volume is its only back suspension. Can tune to Fb 100-150Hz. No less. 300Hz crossover would bring the C-C distance within λ/4 as made. That's as far low I would try cross. Possibly with second order high pass for better power handling.

It is indeed a parcifal encore,the last generation before the parcifal ovation,and has a very good scanspeak tweeter,customized for Verity audio ,as Salas said.
