You guy's were not paying attention:

Or, are we paying too close attention, like proper train spotting geeks?

The custom Navy blue speaker linked uses the Ellipticor tweeter with an Illuminator woofer. The tell is the curving reinforcement only seen in the Illuminator mid/woofers. The Ellipticor woofers feature a smooth cone, elliptical dust cap, and cover for the mounting bolts.

These disassembled shots from Troels Gravesen's (
http://www.troelsgravesen.dk/Ellipticor-1.htm) site showing the details of the elliptical voice coil are this audio geek's idea of porn.


Look at how long that elliptical voice coil is!!

And the tolerances they must keep to fit together elliptical voice coils into magnetic gaps. As someone involved in manufacturing I look at those and want to say to Scanspeak "now you're just showing off".
I will offer a semi-educated guess that Salk will wait for a deep pocketed patron/customer to show up to get into the Ellipticor based systems. In small quantities Scanspeak woofers are priced in these ranges based on product series:
- Discovery - $70
- Classic - $160 to $175
- Revelator - $200-$340
- Illuminator - $280 -$320
- Ellipticor woofers - $675 - $690
- Ellipticor tweeter - $460
Those prices are Madisound retail per driver, not for a pair. Even with a good manufacturer's discount for a pair of Ellipticor woofers and tweeters you are looking at circa $2000 just for the drivers.
