Abstract: Provided is a loudspeaker system capable of easily determining control parameters for controlling the directional characteristics of a speaker set including two or more speaker units. The loudspeaker system is configured to include: a speaker set 11 including two or more speaker units 2; a camera 15 adapted to photograph an acoustic space of the speaker set 11; a monitor 22 adapted to display a camera image 30 photographed by the camera 15; and a directional control parameter generating part 24 adapted to generate directional control parameters providing the directional characteristics of the speaker set 11. The directional control parameter generating parts 24 includes: a target position designation part 101 adapted to, on the basis of user operations, designate target positions 32 on the camera image 30; a directional control angle calculation part 103 adapted to, on the basis of the target positions 32, obtain directional control angles θ with respect to a front direction of the speaker set 11; and a directional control parameter determination part 104 adapted to, on the basis of the directional control angles θ, determine the directional control parameters.
