In modern audio systems, the signal path is generally digital in nature, with the notable exception being the analogue
loudspeaker. Digital Loudspeaker Arrays (DLA) have been proposed as an alternative approach. Generally, they have a relatively
poor acoustic output, as high audio quality requires an impractically large number of speaklets (tiny loudspeakers). We address
this limitation by proposing an increase in the number of quantizing levels, thus requiring fewer speaklets. A comprehensive
system simulation has demonstrated the feasibility of such a system to produce high quality sound, with a hardware
implementation currently being investigated
