I don't know anything about their speakers, but damn, what a horrible website. It looks as though it was designed in 1995.
Kilpisch + Ojas kO-R1
I get the cooperative marketing thing (ooh, aah, esoteric aura...), but my simple question is this: why would you mount the woofer behind the baffle rather than in/on it? A cursory review of Ojas' other speakers indicates this is a common design philosophy. Doing so must create measurable, if not audible, diffraction. Is there another potential benefit to doing it this way that offsets the diffraction, or is it simply about reducing the manufacturing costs?
