I heard them.. They are surprisingly good for B&O, however they are WAY too bass heavy for me.
I believe I spotted in
"The Dark Knight" Bang & Olufsen's Beolab 5 speakers. They look like something out of a SciFi film. They weren't as obtrusive as I would have thought they'd be. I don't think they could have been anything else. Anybody catch them in Bruce Waynes's penthouse? Tell me if I'm wrong.
