The Manger drivers look to be one of the more interesting drivers available
and there are both kits and finished speakers available using their bending
wave drivers.

The Zerobox 103 seems like a natural for review in SP.

Is there a chance this might happen and what has kept them out of the
magazine until now?

Are there any speakers using the bending wave driver that have been reviewed
by SP?

In the unlikely event that you have not previously seen the 103 here's a
