	<span lang=\"EN-US\">A hemispherical array of 196 independent
loudspeakers has been constructed for laboratory research on spatial hearing,
auralization, sound-field quality and spatial audio signal processing. The
array of small loudspeakers is supported by a geodesic frame with a radius is
2.4 m. With this relatively high spatial density of sound sources, spatially
quantized rendering of sound fields should be viable for a variety of applications,
and this paper considers the potential and limits of this approach in relation
to human spatial hearing capacities. The paper also considers the combined use
of multiple loudspeakers for the rendering low-frequency components of sound
sources in order to extend the low-frequency response of the system.</span>
