I was in my brother's store listening to his B&W 802Ds in the "best" room there. There was an 18" Velodyne sub directly to the left of the seating position. On one track that starts with acoustic bass panned hard right, we could not tell that the sub was to the left of us, and this was deliberately trying to listen for it, knowing it was right (left) there. We could feel it vibrating when we touched it, so I knew it was playing.
Sorry but I don't know if the 802s were high-passed or not or the low-pass on the sub.
Anyway, my $0.01.
