Frank Zaayer, one of Sound Projects' senior designers, told us: "Since we could not be amongst the first on the market, we were determined to develop the best line-array system physically possible, naturally including the obligatory iso-phase wavefront control and cabinet shape that guarantees uninterrupted wave fronts and minimal losses for all frequencies - a combination of demands thus far only obtained by two or three manufacturers."
Zaayer continues: "Many sleepless nights and prototypes later, we ultimately got the vertical high frequency directivity right with help of the Wave-Shape-Transformer - an integrated HF driver waveguide and loading device in which all waveguide path lengths are identical. Thus absolute control over coverage angles is guaranteed."
According to the company, polar plot and isobar measurements confirm that the Sound Projects Wave-Shape-Transformer generates a vertical flat wave front above 1000Hz as well as a soft-edged, constant directivity, horizontal wavefront. In addition, say the company, the Wave-Shape-Transformer presents a smooth, mathematically correct flare with improved driver loading. A patent on the innovation was applied for and granted in 2002.
Located in Hilversum, The Netherlands, Master Blaster/Sound Projects is a leading manufacturer of active sound reinforcement systems. Master Blaster was founded in 1986 and distributes her products world wide through independent representatives and importers.
