Abstract: Compact spherical loudspeaker arrays exhibit controllable directivity, and electroacoustic music recently became interested in using their beamforming capacities to compose spatial music. In particular, directivities of 3rd-order or higher turned out to o?er a suÿciently precise horizontal control. Our engineering brief proposes the 170 compact spherical loudspeaker design that is DIY-3D-printable and only uses 8 audio channels. The 170 array houses seven 2.5” broadband transducers that allow third-order horizontal beamforming and a 6” subwoofer. We make the CAD model, electroacoustic measurements, and control filters openly accessible and show it’s beampatterns for verification, based on those measurements.
