Interesting, what could they be used in?

Indeed I did...
I think (from memory) that the B&C had a slightly elongated slotted hole that allowed a little tolerance, and I used the outer most end of the slot for the bolt hole rather then the centre of the slot. The B&C would happily fit in the eminence bolt pattern, but not the other way round........took a whole lot of trouble to sort out that problem, and ended up re-drilling a new set of bolt holes in a fully finished DR chamber....not an easy task

Another point in fact:-
...the eminence 8" driver used in my wedghorn has 8 bolt holes, yet the eminence 8" sealed mid range driver for my new Omni 15 I am building only has 4....... I can only think that the sealed chamber adds a little stiffness to the driver basket....

DR200. Wedgehorn too, but overkill in that.

Another point to the DR200.... it keeps on looking better and better...

does it look like it could be better than the Beta 8A? or maybe lighter?

It's heavier, models better. Come spring I'll build one using it to test.

Bill,I can be a guinea pig for the pro8 driver if it fits.I can always try if it fails I'll rip it out and wait till spring.

Yes, I put a DL2-2510 in a DR that was originally built for a Beta 10. The Deltalite went in, but it wasn't easy. I try to avoid removing the driver at all cost for fear of killing one or more of the TNuts in the process.

It won't fit into the current design, as the frame actually measures 9 inches across. It would therefore be part of an update.

Allright.I am always looking for your bigger and better.I'll wait then build and compare them.
