It's a 17 array loudspeakers sound line devised for a high vertical directivity for the coverage of long distances in acoustically difficult environments. Is characterized by a large frequency response and a low distortion. With compact size realized in a curved plywood cabinet, painted in light natural walnut, acrylic grey or white. The acoustic outcome is pleasant with an effective presence effect; with the electrical connection used the optimal control of the close field and far field are guaranteed. The manufacturing characteristics, the materials used for the products and the transducers are fundamental elements for obtaining an high intrinsic value sound line. The selection of materials is accurate and aimed to the highest production levels.
