Obscure companies making excellent speakers?

Curious if anyone has heard Feastrex. These must be partnered with an enclosure of choice. They are notable for the exotic magnet construction & for their potential to surpass Lowther as a high-efficiency single driver.

i heard the feastrex driver at the show. you can have it, and take the lowther two. both are not too my taste. i hear an unbalanced frequency response, i.e., too little bass and too much treble.

Dgarretson, I got to hear the Feasterex at RMAF, where the installation was much more musical than their installation at T.H.E. Show. The driver is easily at the top of the full-range driver firmament, like PHY or Fertin.

Audio Mechanica of Fort Collins, CO, is another for the list.

Anyone looking into Feastrex online already knows how ardently I admire them, so I won't repeat all that here. Another really nice Japanese speaker that is cheaper than Feastrex is the Flat series of drivers made by FAL. I heard their Supreme-S and was extremely impressed. If I was not a Feastrex user I'd probably be using FAL.
