Peter Moncrieff is FOS on a lot of that stuff. Even though he did manage to get a few things right, all in all, don't put too much stock in everything he says in that review.
For instance, he talks of the "kick-back" force in all the non-W1 sub cabinets. Well, just out of curiosity, I filled up a 3- liter bottle of water and put it right up beside of against the side opposing the driver on a B5 cabinet during WOTW. Didn't so much as see the water even slightly ripple once. :rolleyes: :p
As for the B5 vs the W2, the W2 will obviously provide more placement option flexibility, while the B5 will also serve as speaker stands, and perhaps slightly better integration as 2 channel, full range, point source speakers, as you said yourself.
I say keep 'em both. :D
