In Reply to: Well - Line arrays are a taste in audio and difficult to pull off well posted by airtime on April 26, 2017 at 08:30:19:
line arrays are very difficult to test. They are pretty easy to pull off, however. A single microphone position is not equidistant for all the drivers, so every measurement you do (especially swept sine based measurements) will yield non smooth results. This is true for panel speakers as well as spaced dynamic driver. However, This "line array" is a little different, too, as all drivers are not receiving the same level signal, The idea is to create a "wave front" and this kind of design does do this.
The lobbing effect is measurable but not really audible on tradition line sources because of the Hass effect - but note that ideally we are going to do a floor to ceiling line source like Roger Russell's IDS25.
I've listened and enjoy many line array and ribbon speakers over the years and owned a built a few. The McIntosh XRT series (XRT1 especially) sounded very nice as lines sources - And the IRS system is legendary.
Line sources do have a different dynamic, and often lead to relatively low crossover points (150-350Hz) to woofers. Line sources minimize the energy in floor and ceiling reflections.
