1. A system for controlling a multi-beam constant beamwidth transducer (CBT) array, the system comprising:
a loudspeaker assembly including a constant beamwidth transducer (CBT) array of transducers configured to transmit a first sound beam at a first tilt angle into a listening environment;
at least one controller programmed to:
receive an input indicative of at least one of dimensions of the listening environment, a location of the loudspeaker assembly, and a location of at least one user in the listening environment; and
dynamically control the CBT array of transducers to transmit the first sound beam at a second tilt angle that is different than the first tilt angle into the listening environment based on the input,
wherein the input corresponds to at least a captured image of the dimensions of the listening environment.
