message: explanation of the math involved in line array systems.
My input is the inconsistency in numbers in calculating the difference between spherical SPL and cylindrical (Theory section)
"the sound intensity quarters for every doubling of distance from the point source. Sound intensity is the acoustic power per unit area, and it decreases as the surface area increases since the acoustic power is spread over a greater area. The ratio between two acoustic pressures in deciBels is expressed by the equation dB = 20log(p1/p2), so for every doubling of distance from the point source p1 = 1 and p2 = 2, thus there is a sound pressure decrease of approximately 6 dB."
shouldn't this p1 and p2 be 1 and 4, as it says the sound intensity "quarters"?  Then in the cylinder dB calculation the article says p1 = 1 and p2 = 4 when it should say 2.  Then the calculations should be dB = 20log(p1/p2) = 20log(.5) = -6 while 20log(.25) = -12. Rick Granberry (talk) 16:25, 29 January 2018 (UTC)

thread_title: deleted advertising for XLSA

message: This page has gone from a stub to totally obliterated.  The formatting is awful as is the additions by 213.37.99.84.  This page needs MAJOR reworking with accurate and far better organized explanations on how all line arrays work.  They all have common characteristics that can be explained therefore not pushing any particular product line.  Though some on Wikipedia seem to argue that saying anything good about a product that is developed by a sole company (which is usual a historical fact) is advertising.  Let's see what we all can do with this destroyed article. --PM - PhilyG talk 17:42, 7 November 2008 (UTC)

thread_title: Wow, Just....Wow

message: is this a strictly predefined number? I mean can I buy one line array element(unit) for each side (right and left) rig it up and try to run it that way? There d be no need for delays and stuff, so would it change the whole idea of a line array, becouse it requires some particuliar number of units to be stacked together, or it doesnt?  —Preceding unsigned comment added by 77.35.32.95 (talk) 11:11, 18 July 2009 (UTC)

thread_title:  External links modified 

message: > The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther 
Yes, "interference" includes constructive and destructive.  But for simplicity and conciseness, how about "they  add to each other to..."?
I did a text search for the terms "bass" and "response," and didn't find anything, which doesn't speak good for an article on loudspeakers.  For me, the big deal about laying identical drivers next to each other is that they provide lower frequency response than an individual driver, by combining for a lower natural resonance, enabling the ability to deliver lower frequencies that a single driver might not even be able to make audible on its own.
Regarding the lowering of the resonant frequency by creating the line array, the idea is that if all the cones extend at the same time, they all contribute to compressing the air mass in front of the array, which impedes and slows down the cones from extending.  Creating a mass of "heavier air" effectively reduces the resonant frequency of the speaker, enabling really low frequencies from a line array.  That's all I know, or else I'd edit the article.
But like I say, if the article doesn't include the words bass or response; and maybe even treble is an issue. Nei1 (talk) 21:05, 13 May 2019 (UTC)
