The i and j versions of the P10 have different vertical directivities: 5° for the P10i and 15° for the P10j. The projection of the P10j is asymmetrical. Its J-shaped design diffuses sound downward, a function achieved through its mechanical design without onboard DSP. The horizontal directivity of the P10i is 100° and that of the P10j is 120°. The line-arranged and calibrated speakers for narrow vertical directivity ensure that the P10i/j speakers are excellently suited for large spaces with long reverberation times as well as outdoor applications requiring long range. All P10 models are designed for integration within voice alarm systems. Finish available in a choice of forty colors.
