How many people would this cover outside?

[A.M.Productions]

Thinking about running 4 RS220 per side stacked two high with the top boxes flipped, and 8 dual 18 subs center clustered.

[RoadRanger]

750 at rock concert levels, considerably more at a more "family friendly" level.

[WynnD]

Family friendly is good, because not everyone will want to stop their conversations for a band. They always need someplace close but quiet enough to talk without shouting.

[RoadRanger]

6000 at WynnD levels .

Unless it's a rock concert! ..... You always respond with your personal preference as if its universal. If it's a rock concert then nearly EVERYONE will want to stop their conversation for a band because the band is why they are there. That's the expectation. If they need to talk or take a call THEY will move to a more convenient location for THEIR needs versus tapping the sound guy on the shoulder and telling him to turn the band down.

Yeah how loud is how loud the promoter wants it to be is the correct answer. If Led Zepplin or the WHO is reuniting I want it ear bleeding loud. (I think both bass players may need subs) ;-)

I raise your estimate to 12000 at Wynd levels loool

Ok. Thanks for the help. Thats why i love those boxes, so freaking directional without much spillover, so there will be quiet zones and loud as heck zones. The subs will be in a caroid setup too.

[RoadRanger]

The subs will be in a caroid setup too.

Be careful, cardioid subs arrays generally give up output for that directionality. OTOH with delays or by properly staggering the subs you can steer their pattern - you usually need to broaden their pattern anyways vs what a straight line of subs gives you (a very narrow pattern not much wider that the sub array).

Maybe those boxes perform better than their specs would suggest, but I'm wondering if 8 dual subs wouldn't outrun those tops. I guess it would also depend on the music.

 

A few times a year, I run two Yorkville U15's outside. One Yorkville LS2100P sub or even an LS801P has been a good match. That's for about 200 (plus) people. However that's generally for Classic Rock and R&B - not super bass heavy.

This translates to about twice the sub power vs top power indoors and four times the sub power vs top power outdoors. YMMV, void where prohibited, "it depends" etc .

 

[agedhorse]

Cardioid subs loses a couple dB of average SPL due to energy-phase management losses. In general, I am not all that enthralled with cardioid subs, it often looks better on paper than it sounds in practice.

If it's too loud ..... your too old

 

... at least with respect to subs. No one enjoys the ice-pick-in-the-ear PA at any level.

Flipping , stacking, splaying whatever. Coverage is the key here my friend. If you are unsure about this JBL, EV and many others have white papers with diagrams and instructions on proper coverage.
