Yes that is what I meant; "Line Source Array" is the technically correct term, though seems people will just say "line array" when that's what they mean. I understand your correction of the terminology; I do the same the same thing with my customers and their P.A. language; drives me nuts when they use the wrong term:)
Are most line source arrays that you see in use not supposed to be "full frequency" (by which I assume you mean 20Hz-20kHz)? By that I mean they go down to about 80 or maybe 100 Hz. So wouldn't the 8+ (or larger) box-per-side rigs be tall enough to achieve 100Hz-20kHz properly? Still learning the physics/science of this stuff:)
Another question: So with regards to your second statement, all the "small-format", "line array," boxes out on the market now (JRX, Yorkville Paraline, Mackie has one too now), are they really doing anything different from a point-source box turned sideways, just with wide horz coverage and narrow vert coverage?
Thanks Boomer:)
