Default Just placed my pre-order..

for the Fostex FE166 ES-R from Madisound..

It will be interesting to see what the sound quality is like. (I'll try to test them when I get them and provide results - expected around mid-feb.)

Considering the materials it a freak'in bargain. Both Cobalt and Lanthanum are VERY expensive rare-earth elements with generally better (smaller) crystal structures and capable of higher gauss. Both of these attributes are associated with better sound. Then pop-in the bonus of the voice-coil material which should reduce oxidation (particularly the non-conductive variety) and again reduce crystal structure problems.

wonder if Pass (and friends) have placed their order yet?

Could you give us the Madisound link for that, please. I couldn't find it.

I have had this driver for a few weeks. It was a sample sent to Madisound for eval. You will definately be pleased with it. I have not had it in a suitable enclosure so my listening has been "open", still it's obvious that it is *special*. Expect full bass and wide open highs and amazing power handling. I would also reccomend the factory cabinet or backloaded horn of similar length.

cool..(drool). Late Jan./early Feb. seems like eternity now.

As for enclosures I'll be doing something VERY different to get the best midrange possible. It will have an "expansion" but the termination will be closed with aperiodic venting. Targeted response will be 200Hz and up. I'll probably add a piezo in an odd-manner for the highest freq.s. Dipole pro woofers below 200Hz. Powered T-Line for freq.s below 50Hz.

Now I need to go convince BrianGT to produce a current gain-clone monoblock kit..

Why do I believe that adding a tweeter will just screw things up?

supertweeter Bill, supertweeter.

In particular I'm thinking of making one omnidirectional. i.e. cut the horn flare off and fire it upward into a 360 degree reflector. (..yup, I do think a bit differently). This should provide a steeper acoustic high-pass to the piezo while giving the speaker more "air" and hopefully a more linear response off-axis. Besides, its a cheap tweak (if it sucks it finds its way in the trash without real regrets).

Here is a minimalist comercial design that uses a piezo (note the difference in remarks between the trio and other loudspeakers):
