RE: Why do line arrays using directional speakers require shorter lines for similar near field performance?

Posted by Rafaro on April 26, 2017 at 18:45:50:
About 7 years ago when I investigated this there were several linear array models which had a cardioid LF section in their flown cabs. Because of their improved LF projection it was suggested they would require a shorter line as compared to non cardioid models for similar near field LF performance. I could never understand clearly the science behind it. It would now take considerable time to try to recollect all that info....some models are not even made anymore. But if I can recollect that info I�ll post it
