J_Rock, Thank you. I was afraid the wood might rattle loose and fall into a driver so I though some bracing was in order. The 1X2 mdf between the drivers is slightly press fit before final tightening of the drivers and glued with Gorilla Glue. As anal retentive as I can get sometimes about 'beefing things up' I remained true-to-form; Get this... I stapled a heavy gauge nylon string to one of the pieces of wood (at this point in time it hasn't occurred to me yet the proximity my METAL stapler would be to the magnet) then about four times I tightly wound the string around the base of the wood against the magnet base and stapled the end. Since that still wasn't enough I though I'd be a good idea, since Gorilla Glue expands, to coat the string with it. The wood is pushed up against a small dome in the center of the Dayton. Seems very sturdy, just don't ask to change driver orientation......easily.
60ndown, it's not a very good picture from a perspective standpoint, but that driver assembly was centered. I spent a painful amount of time agonizing the perfection of that very point.
DirtDawg, Thank you. I'm not sure I can get a camera in there any more. I did make a 6" access square (acoustically transparent) but not sure if I'd get a good photo sticking the lens in a dark hole. ( insert joke here ) and yes, Blather is going for word of the week if Sam has his way... As far as Webshots go, It seems ok to me. Haven't found any ad/spyware yet lurking on my machine. However I occationally get a small window that pops up by the clock telling me about new daily pictures I can view, but you should be able to turn that off. I chose it based on a recommendation of one of my customers at work. He saw my frustration, and said he had used them with no problems. He caught me in a weak moment and while visiting the site I decided to go for it.
Adrian D., Yes part # 295-130. These are what I've got.
Seating will be here Tuesday !
Shakers are wired. Yes with 12 guage Romex about 30', then 14 guage RCA wire (premium?) from Aura to Aura. Couldn't resist, so I wheeled up my PC chair and....well....you know the end of that story. So now I now have a wooden rocking chair for my temporary PC chair.

Very cool things these Aura's are.
