The third version of our FR loudspeaker series used metal-filled filament to add density and stiffness to the enclosure. It worked in that regard, but the material was unpractial due to brittleness both during printing and in the final product. For the fourth version we switched to wood-filled filament, which is more ductile and easier to process. The shape of the enclosure remains the same as in the FR3, because it was proven to be very good in terms of resonances and edge diffraction. The diameter of the driver, enclosure and tripod legs was reduced to obtain a more slender design for desktop use. The binding posts are upgraded to sturdy Dayton Audio binding posts. The driver used is the Tang Band W3-1878, and the leadscrews for the legs are 12 mm.
