摘要： A horn coupled to multiple acoustic transducers includes first and second throat portions and a mixing area integrally formed with the first and second throat portions. The first throat portion has a first throat opening adjacent to a first transducer, and the second throat portion has a second throat opening adjacent to a second transducer. The mixing area includes a common mouth opening shared by the first and second throat portions for at least one of transmitting or receiving acoustic signals. At least one dimension of the first throat portion is different from a corresponding dimension of the second throat portion, so that a first cutoff frequency corresponding to the first throat portion is different from a second cutoff frequency corresponding to the second throat portion.
