3.5.Live applications (mobile)
For a mobile application, whether it is an outdoor or indoor installation, the
common location is to place the bass units (one or two per channel) on each
side of the stage.
Fig.11. Mobile applications
To obtain a clear and free-distortion reproduction, it is advisable to place the
mid-high units on top of the low units keeping between them an approximate
height of two meters. If such height cannot be achieved nor maintained, it is
advisable to use the classical tripod for each mid-high cabinet and leave the low
units on the floor.
WARNING!!! For installations that suffer from acoustic problems and in which it
is necessary to reinforce the response in the low frequencies, it is advisable to
group all the subwoofers together in the same point. By this way, cancellations
will be avoided and a higher acoustic pressure level will be obtained.
3.6.Asymmetrical and rotatable horns
The EL-10, EL-12 and EL-15 models incorporate an asymmetrical dispersion
horn which will optimise coverage either in horizontal or vertical position.
To rotate the horn, unscrewed the frontal grille, and then, unscrewed the four
fixing screws of the horn. Rotate it 90 degrees taking care of the wires. Screw
the horn again and finally place the frontal grille in its right position.

Good coverage of audiences often is a conflicting combination of:
* wide coverage for the closest audience (short throw)
* narrow coverage for distant areas ( long throw )
