A Few Important Caveats

While applied phase cancellation can shape the vertical dispersion of the speakers in a line array, their horizontal dispersion is not affected. So in effect, an individual speaker in a line array may wind up with a 90° horizontal dispersion by only a 20° vertical (for example). Also, even though phase cancellation can achieve a line-source distribution and dramatically improve long-distance coverage, as distance increases, even line arrays begin to take on point-source characteristics and succumb to the -6dB per doubled distance of the inverse square law.

There are limitations and caveats to a line array’s ability to approximate a line-source function. First, the overall top to bottom length of the array determines the lowest frequency that will behave accordingly. This is simply because as the wavelengths get longer, the relevant time arrival distances at the listening position must be greater to achieve the effect. That necessitates a longer array. At the other end of the spectrum, the wavelengths become so short that the drivers are too big to be placed close enough together, so the relative phase differences become too great to achieve line-source function. In those cases, waveguides (horns) are used to achieve enough directionality to approximate something between a point-source and line-source function.

CAUTION

Loudspeakers produce a static magnetic field even if they are not connected or are not in use. Therefore make sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be impaired or damaged by an external magnetic field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic data carriers (floppy disks, audio and video tapes, bank cards, etc.) is sufficient; a distance of more than 1 m (3 ft) may be necessary with computer and video monitors
