Mikael Abdellah said:I'm not sure line array is the same. I will be putting all drivers in a big sqaure. Will this configuration behave differently from a line array or is the theory the same?
bessel array ?
Completely differently (to a line-source). Have a search of the older audio books from the 1950s - early 1960s and you'll see that speakers, admittedly not using 3in drivers, but similar in concept, were quite popular once upon a time. This might interest you, particularly the Sweet Sixteen section: http://www.roger-russell.com/columns/columns.htm
Do you mean something like this:

Hi,

Your short array is a small square and thus what is considered for the vertical dispersion will also apply for the horizontal, see the first picture.
Stacking several vertical line arrays made with point sources horizontally makes a plane source array to a certain extent, see the second picture where a T-line array is suggested as a complement.
The normal line array SPL/distance plot can be extended with a short ‘Close field’ region depending on the horizontal length (width) of the array where the SPL versus distance is constant(0 dB/ octave) and that extends to about the array-length/ 3.14 where the Nearfield (3 dB/ octave) takes over as can be seen in Jim Griffins papers: http://www.audiodiycentral.com/resource/pdf/nflawp.pdf
