Those Brahma's were beasts. I had the pleasure of hearing a 15" I believe in a diy sonotube in a home theatre setup when Adire was still in business and it was absolutely jaw dropping... and he said it was dialed WAY WAY back so it didn't overpower the 35,000.00 a piece left, right, and center channel speakers. Guy was a FIREMAN of all things... I guess they make better money than I thought they did. Best home theatre system I've ever heard, by far. Opening of Saving Private Ryan I was dodging bullets and explosions. I'd say he had an easy 200k in his home theatre, which isn't a LOT for that crowd, but it's the best I've ever heard.
