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."
