    Abstract: Implementations of the subject technology provide directional acoustic devices such as directional speakers. A directional speaker may include a sound-generating component that projects sound from an acoustic port, and has a rear or interior surface that interfaces with a back volume of the speaker. The directional speaker may also include one or more acoustic ducts coupled to the back volume that direct a negative polarity version of the sound to one or more desired locations in an external environment of the speaker. The negative polarity version of the sound may cancel portions of the sound projected from the acoustic port, at one or more desired locations in the external environment that are determined by the arrangement of the acoustic duct(s).
