You can get a similar effect with a floating or semi-floating floor and a huge sub hanging from the ceiling. You have to tune it though.
If you are on the Bay Area, The Great Northern had a setup like that on the hallway at the entrance before the main floor. They use VOID for their soundsystem but I don't think that particular part of the setup is COTS.
they actually had to turn down that system for being too loud. but at that level, none of the stuff is really COTS because it requires a ton of tuning due to each particular venue's layout and acoustics
I don't think the subs hanging from the ceiling on the hallway in front of the bar are COTS. If they are it's not on their websites or catalogues. Like it may be the same cone but it's not the same enclosure or anchoring.
