Question

A central loudspeaker cluster provides sufficient coverage to the auditorium where it is installed except under the balcony. A secondary loudspeaker is installed under the balcony. A listener in the second to last row is 65 feet from the main cluster and 7 feet from the secondary cluster. For this listener location, what is the ideal electronic signal delay for the secondary loudspeaker? Is the amplified sound arriving within 25 ms of the direct sound?
