An 8-cabinet array has a near field extending to 19 metres at 2kHz. Beyond this
distance the wavefront will be spherical.
In the first zone (Fresnel), sound pressure loss is only 3 dB per doubling of distance,
whereas in the second zone (Fraunhofer) the loss is 6 dB. In long throw and high
SPL configurations it is very important to produce cylindrical waves.
