Parkhurst,
Its a DIY of my own design, you can see them on my systems page.
Basically they contain the Arum Cantus G-1 Ribbon tweeter and a 7" ScanSpeak Revelator in a purchased high gloss highly braced sealed enclosure.
I created an external crossover box. In it I used top of the line Mundorf SGO classic caps, Jensen inductors and Path Audio resistors. The speakers are wired internally with Cerious Technologies wire.
I am also bi-amping at 80hz to (2) JL Audio F-113 subs.
They sound really good.
