PA Question

[stewblack]

Where is the best place to sit the sub in a standard two cabs on poles, one sub on the floor, type PA arrangement?

[KingPrawn]

Any where you like really. Most are set on a single pole with sub then speaker on top. The sound from a sub is omnidirectional. The frequencies are generally below 200HZ.  So it’s an almost 360 degree sound. Not to close to walls and corners can some times make them sound louder. There are calculations about distance to walls and radiation and Phasing issues  however generally anywhere. Depends on the venue.

We put our sub at the back next to the drummer on the opposite side to me to try and get the bass out evenly on both sides of the stage, however, knowing that sub bass frequencies are not known for doing what we want them to it probably makes very little difference, other than giving us somewhere, away from grubby fingers to sit the PA head!
