My inexperience catching up with me

[J M Fahey]

Even if a hall is a mile long, low power background music means each speaker just fills its own area (say, 4 or 6 meters around), can *barely* be heard under some of its close neighbours , if at all (say, 8/12 meters), is absolutely inaudible beyond, so delays are useless.
Besides, who should be synced with whom?
Absolutely different is when you have a dominant sound source (e.g. a performing stage or, say, a lecturer or Priest/Minister) and you want to reinforce the fading-away main program.
But, on background music (or voice announcements as in bus stations or supermarkets? Forget it.
Simply there's nothing to correct.

I think there's advantages to being an old timer, one of which is to be free with opinions, and say what you think.
I have told people who are trying to nitpick, that I haven't decided whether to accept them as a customer or not, so they may want to go talk to the guys down the street. (We get a lot of folks moving here from somewhere else).
They have never been told that before!

Enzo: Perhaps if your had a username boasting of your prowess...
I'm not so surprised to hear that stuff about the sound system from someone who lists their occupation as "sound contractor" (assuming it was the same username). Could you have been jeopardizing potential profits?
I only wish I had got let off as easy as you .
If it makes you feel any better, here's a gem from same user posted elsewhere, regarding biasing Marshall amps:
"Now here is how the factory biases the amp:
Older model: 1 mv sine wave input should drive the amp to just barely clipping. Too much bias will prevent the amp from clipping with this much input.
Newer model: 1/2 mv audio input will drive the amp to clipping.
Yes, that' really how they bias it, at the factory."
That really had me scratching my head, coming from someone who told me "A. I have been repairing guitar amps since before you were born.
B. I have repaired more guitar amps than you have ever seen, in your entire life." and "So go back and learn about amplifiers before you throw rocks at somebody with 100 times your knowledge."
Full disclosure: those responses may not have been entirely unprovoked.

"I haven't decided whether to accept them as a customer or not"
That is way cool!

Yes indeedy, we reserve the right to decline repair work.

JM, a point I made over there. IN a ceiling speaker array, each person hears the speaker over his head, so if you use a delay system, what does the delay reference to?

If I am in the middle, will the speakers to my left be delayed with respect to mine and the ones to my right ahead of it? And since the stage can be configured either on the side of the room (long wall) or the end (short wall) would the delays all be reset for each layout?

Of course any idiot sitting in a small shop(me, apparently) can throw a sound system together.
