Have you looked at the sprinkler obstruction rules in NFPA 13? Just because an object is over 48” wide, doesn’t automatically mean there needs to be a sprinkler below it unless it creates an obstruction to sprinkler discharge.
There isn’t anything in NFPA standards regarding sound waves and sprinklers. If the sound waves were intense enough to affect a sprinkler, they will have a potential destructive effect on everything within the room to some degree.

There are several large subwoofers (5' x 5') installed at the ceiling. Since they are over 48", we need to install a sprinkler head underneath/adjacent to the obstruction. Is there any guidance for the distance away the sprinkler head should be from the subwoofer to prevent the sound waves from rattling and damaging the sprinkler head? ADAM LEVINE, P.E.
