The use of loudspeaker arrays to create a spatial impression within an auditorium requires the exact knowledge of the synthesized wave eld. The interaction between loudspeaker array and the enclosure can be investigated by numerical simulation. A new method for the computation of dynamical 3D sound elds is applied to obtain the impulse response from a(More)
Various methods exist for crossing over multi-way loudspeaker systems. These methods include those loosely classified as Linkwitz-Riley filters, constant-voltage filters, and D'Appolito configurations. All these methods do not provide broad-band constant-beamwidth or constant-directivity operation because their vertical radiation patterns change shape as a(More)
