[QUOTE="thylantyr, post: 2558729, member: 560358"] To understand the issue better. You need to know what is a line source vs. line array. A line source is a tall and narrow radiating surface, ie you have a 7" contiguous planar, ribbon, etc driver, could be a midrange driver or tweeter, even woofer, lol. A line array is a group of radiating elements in a straight line and it's not contiguous. By definition, a line source speaker is different than a line array speaker. You can have line source performance from a line array design - by stacking drivers close together to create the illusion of one radiating surface. By using the comb filtering formula, you can develop a line array to mimic a line source. You can also cheat a little bit on the design. Problem is; The Gallo speaker claims -> [B]The "LS" in the 5LS's model designation stands for "line source"[/B] Obviously it's not a line source. It's a line array as you have a group of radiating elements; the seperate midranges and tweeters. Furthermore, for it to be a good line array design, by spacing the tweeter elements far apart is very counterproductive to making a proper line array. The midrange can be spaced further apart depending on the drivers and crossover frequency. You can also cheat the midranges but not the tweeters. You said you trust Gallo more than you trust me but science tells you that the Gallo design is a bad design and there is nothing they can do to compensate for everything that is in error in the design. If you were to audition this design and it sounds good, that is ok --- really --- You can say "Hey, I heard this Gallo speaker XYZ and it sounded good". But it would be wrong to say "Hey, I know what a line source speaker sounds like because I heard the Gallo XYZ speaker". **No you did not. You didn't listen to a line source speaker, but you did listen to a poor implementation of a line array * .. lol ... It is also wrong to say "Hey, I don't like line array speakers because the Gallo XYZ speaker I auditioned sounded poor".. * Yes, you did listen to a line array speaker, but it's poorly designed and maybe that's why it sucked... next time listen to a better design *. .. lol ...
