Accuracy!

Geva believes that measurements don't lie—well, he allows that they can fib, but that a competent engineer should be able to interpret them with great accuracy. He uses aluminum and ballistic allow instead of wood or MDF, he said, because they are the "most resonant free, deadest, stiffest, strongest, least diffractive, and most sonically desirable materials ever found."

He uses a computer optimization program he designed himself to create speakers that "have a ruler-flat frequency with near 0 degrees relative phase shift." Other speakers, he maintains, are optimized in either the frequency domain or in the phase domain. Only YGA, Geva said, can optimize both domains simultaneously—resulting in "the flattest frequency response ever measured, along with the best phase measurements ever achieved."

I have a pair of Anat Reference II Studios, and I've come to take for granted their low distortion and realistic presentation of music -- until,that is, I hear other speaker systems. Comparison really does set the Anats off. In my experience, they are exceptional loudspeakers.

Please explain - I thought diffraction was a function of geometry, not dependent on material properties such as density, strength, internal damping etc.

Dear muck raker,Your question is highly insightful. Thanks for bringing it up!Wes Phillips has quoted me very accurately. Here is the background:With soft materials, or those that deform under heat, it is impossible to achieve tight tolerances. Therefore, their geometry cannot be optimized for total elimination of diffraction. At YG Acoustics, we use only high-grade aluminum alloys (unlike the industry standard of aluminum 6061T6, our cabinets use 6061T651, which undergoes a more extensive thermal treatment). They are stiff, stable and do not exhibit deformation during our machining process. We also use a custom-made vacuum table to avoid vibration during machining, which ensures high surface quality. All of this innovative technology leads to geometries which are highly precise, and together with our sophisticated optimization it allows for enclosures which simply do not suffer from diffraction.Sincerely,Yoav GevaYG Acoustics
