The combination of a well-known electro acoustical simulation software with a state-of-the-art room acoustical simulation engine merging the advantages of both to form a multi-purpose simulation tool, is introduced. The new tool is useful for consultants for application in complex situations in medium sized and large rooms. Advantages of combining a high quality speaker database and a powerful 3D-CAD interface with a hybrid image source / ray tracing algorithm including diffuse scattering will be discussed. Details about the room acoustical model and its limitations as well as the extended possibilities of the system are the main topics of this paper.
