Wow, this has to be the most impressive home theater I’ve seen short of the Goldmund Media Room. Elite Home Theater out of Canada has this spectacular setup featured on their website gallery. They do high end custom seating for people who are serious about their home theater.
Not sure if the Bat Cave has the very cool motion controlled D-Box chairs that EHT sells, but if they do that would be about $90,000 in chairs alone.
Check out some of their other home theaters at the EHT link below, most of them are pretty amazing.
