The PL-11’s DML propagates wide and diffuse audio that interacts with boundaries, (walls, windows, floors and ceilings), in an equally diffuse manner. The PL-11 does not generate audio energy that is reflected as coherent first, second, third reflections that are perceived as out of phase, time-related reflections - so the acoustic space is essentially “erased”. Even with such a diffuse output, the PL-11 creates a highly accurate stereo image that is also propagated throughout its very wide output. Nearly every location throughout a venue perceives a stereo image. Complementing the PL-11’s DML is an integrated large-format ribbon transducer with a nominal frequency response of ~7kHz – 22kHz. A shallow horn design provides HF distribution of 120⁰ horizontal by 15⁰ vertical.
