The Sfaira loudspeaker gets its name from the Greek word for sphere. The spherical shape is optimal both for acoustics and material use, but difficult to manufacture using traditional methods. The Sfaira loudspeaker is produced using additive manufacturing (3D printing), which allows complex shapes and almost zero material waste. The enclosure material is Sulapac Flow, which is a brand-new biodegradable plastic with wood fibers.
Technical specifications:
The enclosure is 200 mm in diameter and stands on four rubber feet that isolate any vibrations. The base model is passive with high-quality binding posts in the back. An active Bluetooth version is available upon request. Frequency response is 70-20 000 Hz with wide and axisymmetric directivity. The bass roll-off starts early, but with a slope that allows the use of (unavoidable) room modes to reinforce bass frequencies.
We sell these with a sanded finish but never painted due to recycling or composting being the planned end-of-life solution. You can read more about our sustainability mission in our blog: https://rdphysics.com/2021/11/11/circular-economy-of-loudspeakers/
