The EDGE212P is a 3 way, horn loaded system of high efficiency. The mid-bass section is equipped with two 12'' loudspeakers connected in parallel and coupled on the same horn wave guide. Each cone has an impedance of 16 ohm and has a demodulation ring for reduced distortion. An elliptic-spheroid wave guide housing a special 2'' compression driver reproduces the mid-high frequency band from 800 Hz upwards. This driver is internally divided into two sub-systems: a 4'' annular membrane reproduces from 800 Hz to 7 kHz and the very high frequencies from 7 kHz upwards are reproduced, through a passive filter, by a 2'' plastic film membrane which is mounted co-axially to the former. The wave guide used has been designed specifically to allow an excellent directivity control which is kept constant from 600 Hz upwards. This feature allows the EDGE212P to be coupled in a coherent way even in very large arrays, distributing the audio energy in a uniform way over the listening area. The wave guides of the EDGE212P are inclined downwards by 5°. In the flying configuration, such a down-tilt makes it possible to create more rational arrays. In situations where it is not possible to fly the system, the down-tilt aids in the coverage of the listening area. The result is an improved and predictable coverage, a good audio balance across the whole array once installed, well distributed energy and an homogenous frequency response reducing many of the problems traditionally associated with large arrays of loudspeakers. This all works to improve the fidelity and intelligibility obtainable even in conditions of high reverberation.
