Yah, I really am a little crazy. The speakers that I built to sell didn't fall through, it was ME backing out. I plan to sell the unreleased 12" full range Audio nirvana drivers, and buy their top of the line ALNICO drivers for $600 extra! To do it, I must sell not only these drivers, but the 8" co-axial drivers as well made by the same company. So the 12", I will be asking $300 a pair plus actual shipping, and to keep things simple, I will sell the 8" for the same price. God, what a month. Pictures to follow, or look at the post that I have comparing the FRX2 and the co-axial drivers awhile back. I'm tired, better go to bed.

A shot of the 8" Co-Axial driver. So there you have it, a set of 8", and set of 12".

You are correct. This driver will be the largest driver W/O a whizzer cone when it comes out. I was looking at the 12" ALNICO drivers, and they are pricey. What is your take on them compared to the other drivers that you own? I have also been the owner/builder of 4 sets of AN speakers. Interestingly, I ended up with the ZOB.

JD,

   I am ALWAYS curious about new/different designs regardless of their success or not.
  Now, regarding the ZOB design, you will want to make sure that the driver used is compatible with an OB design. I know that these parameters have been discussed in the ZOB threads, and that one important thing is the Qt parameter of the driver. Sorry I forget what that refers to at the moment, but it is one of the most important things that Steve talked about when designing the FRX series of drivers.
I also know that whizzer cones have their plus and minuses, so again it is a point of consideration.
