There are beta programs going on all the time for new boxes for new drivers particularily the ones we haven't built.

At the moment that would include the (as yet skimpy) Alpair 6.2 set and the uFonken88 (adapted uFonken for Fountek FR88ex). There will also likely be betas for the new Fostex FFxx5WK -- still haven't seen full data for these even thou i expect i may have some in hand as early as end next week.

nothing "micro" about the Bookers, or Basil Hayden's for that matter, except for the batch quantities

The cabinet for the FE127 is too big for the FF125wk.

A free set of CGR dFonken125 drawings shortly.

Cool, out of curiosity, what is the purpose of the piece of wood behind the driver? I was assuming when there's a lot of bass, that the driver would want to move back and forth.

it might tend to, but the only part of the driver you want to move is the drive train & cone/diaphram

as to the enclosure, there are lottsa schools of thought on construction materials & bracing schema - to put it simply, some of the tenets of our general architecture are: high quality multi-ply plywood ( i.e. Baltic Birch, Apple Ply, Finnish Birch etc); strategic bracing (including of driver to enclosure); and if you carefully analyze drawings, aspect ratio of the 3 dimensions

that piece of wood behind the driver is part of the bracing scheme
