Jim Salk at Salk Sound made an active speaker using these Arya products and Purifi woofers.
The overall sound was apparently excellent but very cost prohibitive. You can read the posted thread but the general impression I interpret from Jim is that they are not worth the premium over using the Satori Beryllium driver on his SS9.5s.
