The line array is far too big a thing to set up in the same way, and once it's set up you don't really want to have to move it, so you need to be sure that the positioning is right, the height is right, the horizontal angling is right, and — most of all it — that the array takes up the optimum J–shaped curve to distribute sound evenly to the front and back of the audience, and everyone in between.

My part was designing the cabinet dimensions so any possible standing waves within the cabinets would be 1/3 of an octave apart. Harry Olson's book, Acoustical Engineering was also mentioned. Both books contain the fundamental line array descriptions and mathematical analysis.

11 dec. 2020 — Linjearrayeffekten av förträngningen av strålen med ökande frekvens demonstrerades först av den akustiska pionjären Harry Olson .

Both books contain the fundamental line array descriptions and mathematical analysis. David Lee of Rhino Acoustics gives a description and listening test of the BassMaxx speakers, using their own program material. That was the reason because it was a line array, as originally theorized by Harry Olson in the 1930s in his book/treatise (of which I would be happy to send anyone a pdf copy- warning: lots of math).

The line array effect of the narrowing of the beam with increasing frequency was first demonstrated by acoustical pioneer Harry Olson. He published his findings in his 1957 text, Acoustical Engineering. STRAIGHT LINES = Straight Line Array The concepts in this presenta>on have been described in the book Acous>cal Engineering (by Dr. Harry F. Olson) Published in 1947 explained in chapter 2 (Acous>cal Radia>ng Systems) IV.2.3 Curved Array Harry Olson, en su libro Acoustical Engineering, desarrolla las características direccionales de una línea de fuentes que están situadas dentro del arco de un círculo y separadas a distancias muy cortas. Oks balik ke Line Array, Line Array pertama di cetuskan oleh pelopor acoustic dunia Harry F. Olson pada tahun 1957 yang menyusun speaker Column untuk menghasilkan suara lebih sempit dan terarah melalui beberapa driver yang disusun segaris dalam satu BOX, sehingga meminimalisasi gema dalam ruangan. Line Arrays Lines of subwoofers are one application of what Harry Olson discussed in the 1957 text Harry F. Olson, Acoustical Engineering , when he described a straight line source; using omni-directional elements, in a line, all reproducing the same signal, with relative close spacing compared to the wavelength, pattern control can be achieved. The Line-Array, as such, is nothing new; its method of functioning can be traced back to 1930 in relevant literature.
