Here's some assorted porn from the Feastrex president's blog:
211 amplifier (one-off build for a customer in Japan)

Bottom view:
The word is that these sound every bit as good as you might expect them to sound -- top class.
Half a driver is better than none?

An externally hosted image should be here but it was not working when we last tested it.

ck out a more complex part being made:

or, you should see a 9 or 12 axis machine-- they're just amazing!
(not that 3 axis machines aren't amazing in their own right, simple forms like the magnet structures above is made in minutes instead of hours, and drawing programs convert to code, or conversational programing goes much quicker than writing SO many lines of G code...)

I know it's a standard metric thread - probably M6 or M8. Chances are there's a bolt nearby that will thread in with no problem. (One does want to be be careful not to bump up against the bottom of the hole with a too-long bolt. I think there is zero chance of dislodging the magnet but it might create stresses that won't be good.) I'll report back later with confirmation if someone else doesn't beat me to it.

I'm planning to get a pair of entry-level field coil drivers (5-inch) and put them in the original Feastrex 3-port enclosures as that's all I have room for. (And, I happen to like those enclosures.) I also hope to finally assemble my pair of 12-inch Rythmik subwoofers that have been sitting around here for ages. They will go into sealed enclosures. Most of my music will actually fit into the Feastrex enclosures without using the subs at all. But occasionally I like to pig out on pipe organs, and that's when the subwoofers will see action.
As much as I like analogue, the signal source material will be all digital due to space limitations. I have a highly modified Sony CDP (old -- it is based on a pair of the TDA1541A [now S2]) and a LynxTwo sound card.
I will use a simple DIY preamplifier made by cobbling together devices scavenged from Neumann mixers, and I hope to have two power amplifiers (at least initially) to play with -- a highly modified Rotel midfi transistor amplifier that sounds much better than it has any right to, and a smallish PP tube amplifier that will be built from parts on hand. (Unless Mr. Teramoto manages to convince me to go with one of his amp builder's units, although that would be a PP amplifier too.)
It won't be too long now, I hope -- maybe I'll start work on putting it all together after I see my oldest daughter off to graduate school in the Netherlands. That would be in the last week of August . . .

A Japanese DIYer recently came up with this enclosure -- made entirely from walnut planks. I haven't heard it but apparently the sound is quite good and the potential quite high . . . I'm sure there will be a better version of this before long. (I think he plans to reduce the internal volume somewhat.)
