The Persona 3F is a three-way, 4 driver design that includes two-7” bass drivers, a 1” Truextent® Beryllium dome tweeter and uniquely, a 7″ Truextent® Beryllium mid-range/bass driver. Although many special features define the Persona line, the use of Beryllium is a highlight, but not new to Paradigm – the newness is the use of Beryllium in the midrange driver.
It’s highly unusual to compliment the Beryllium tweeter, rare in itself, with a Beryllium mid-range driver as Paradigm has done. Beryllium provides rigidity and stiffness greater than that of aluminum or titanium and therefore reduces the coloration and potential distortion while increasing the high-frequency output. But it’s expensive, produced specifically and to spec for Paradigm by Materion, metals manufacturers based in California.
Paradigm further developed for each Beryllium driver, their Perforated Phase-Aligning Lens, a beautiful spider-web design, which varies slightly from their past Studio line. The lens was designed to “smoothen and widen out dispersion”.
