Audio Artistry information gathering

Blast from the past!  I am a Audio Artistry hoarder.  Reckon I am into all things Siegfried Linkwitz since the old Speaker Builder days.  He was to DIY speaker builders as Nelson Pass is to the DIY amp/preamp builders.  Yes, there are many others to be mentioned here also.  Thanks to my good fortune I just purchased the AA Dvorak Signature.  The cabinetry matches my AA Beethoven.  I have been fortunate to have email exchanges with Marshall Kay of AA but not recently.  Trying to find out if the Dvorak Signature changed the Vifa D26 Aluminum Dome tweeter for a soft dome Scan Speak?  After serval days of listening it does sound as if they did.  Also, anyone out there that would have a copy of the owner/operator manual for the Dvorak Signature.  I would like to have a copy.

The Signature uses four, H style, Open Baffle, dual 12" Scan Speak woofer cabinets so the owner can experiment with a distributed bass configuration.  Wish more speaker designers chose this path.
