It can work ok, to varying degrees depending on the exact problem being addressed. Sometimes active pattern control is used to reduce LF energy on the stage, sometimes it’s used to reduce energy to the sides, sometimes it’s used to focus the energy more forward.Hey guys, esp @agedhorse, who politely replied to me that large events might stack or fly subs as needed.

There are to chief drawbacks though, the first being that there are usually artifacts generated, lobes of LF energy can sometimes show up where it’s not wanted or not expected. The other issue is that the added gear doesn’t contribute to the forward (audience) LF energy so the system grows in size, weight and cost without getting louder.
I have heard both good and bad examples of the different types of active pattern control, so it really depends.
