Proel DS112P Line System Series 2-Way Full Range High Directivity Passive Speaker 'Engineered and designed be a system capable of providing sound reinforcement in a limited area minimising the emission of noise / disturbance to the surrounding areas. Small in size, the system can be integrated to any structure type ceiling, walls and roofs, both indoors and outdoors. The speaker is equipped with custom transducers, studied specifically for this project to create a sound that has both high fidelity and high directivity. The DS112P / T is a two-way speaker system with highly controlled directivity. Its configuration allows it to control directivity as low as medium-low frequencies (around 500Hz), even though the physical dimensions are very small. This marked tendency to control the energy emitted within its cone of radiation especially in the vocal range makes it ideal tool to locate vocal messages in specific areas.
