1. A playback device comprising:
- a first transducer;
a second transducer;
an acoustic grille;
a network interface;
a processor; and
a computer readable medium comprising instructions that, when executed by the processor, cause the playback device to perform operations comprising;
receive, via the first transducer, a sound wave passed through the acoustic grille;
determine an angle of incidence of the sound wave based on a level of the received sound wave and an angle of reflection of the acoustic grille;
adjust an output characteristic of the second transducer based on the angle of incidence;
receive, via the network interface, an audio signal; and
play back, via the second transducer, the audio signal according to the adjusted output characteristic of the second transducer.

Abstract
Apparatus and methods are disclosed for acoustic optimization. An example playback device includes a first transducer to at least one of output sound waves and receive sound waves, a second transducer to at least one of output sound waves and receive sound waves, and an acoustic grille positioned in relation to the first transducer, where the acoustic grille is to reflect sound waves received at a first angle of incidence.
