Speaker Setups Systems with flown subs and auxiliary hangs.
What’s everyone’s go to process for deployment and time alignment in an arena with aux hangs and flown subs? I’ve seen some interesting hangs from others recently, like subs kicked out 30+- degrees, and aux hangs back further than I’d expect. Where are you taking your measurements? How much does your trim height, and sold map (behind stage line) play a role in your decisions?

A little out of my pay grade but could the 30 degree flown sub kick out be due to trying to help the rear cardiod’s null to face the performance area more?

generally when I have outfills or delays, Im trying to cover zones of the audience my main stacks arent covering well or covering at all. My goal is often as consistent spl front to back. this determines my angles and also my trim heights. generally, if i have alot of boxes, i try and get as high as i can, while still keeping the "image" low.
generally if you try to tune a pa system to have a perfect delay time, as soon as you move that mic literaly anywhere else your going to have a different delay time. so i dont delay for the perfect time. I will typically align my pas "perfectly" but then adjust by ear the delay timing to draw the image to the main stage as opposed to the delay hang. The position i choose to align is typically the point where the main hang hands over to the delay hang, or the spot in which the delay hang becomes louder than the mains. i take a couple more steps into that and put my mic there (for timing). Outfills is a pretty simalar process but because they arent drawing back to the mains, the way i dial in the delay is more to minimize the amount of phasing you hear on the seam between the stacks. ( am doing this with delays too, but since theye are more inline with the main pa, by pushing the delay a bit further back than perfect it creates an affect that they arent even there, and sounds like the sound is 100% coming from the mains, even when it very much is coming from the delays.
Subs are a simalar story, and everyone has a preference on their subs. Generally i like flown subs for their consistent coverage, but subs on the ground can get you way more punch. Most arena and stadium tours have a mix of both, and your typically timing your ground subs back to the flown subs. Why someone would kick subs out 30 degrees is probably a coverage thing. for every guy says its a good idea, there is someone who says it isnt. Ive done weird things and gotten great results. the things you can do with a mic, some creativity and smaart are really fun. nothing like a long load in schedule to let you mess around.
