I'm a B&W fan boy (though I object to the pejorative sense of that phrase). I love my 603s and 600 and, just like the article states, wish I could afford something bigger and better from B&W (in fact, the only reason I got mine was because I bought the dealer's demo models for a 30% discount)...
But to say that B&W hasn't had a strong entry in the home theater sub market is probably an understatement. This sub, though, looks pretty awesome. The sealed design and resulting small size is gonna up its WAF.
But, bummer, at $2K, it's not gonna end up in my HT rig any time soon.
So, it looks like I'm (when the $ becomes available) gonna have to stick with either SVS or eDesigns as I'd like to spend my $ on American-made / Rust-and-Corn-belt-made products. Nothing wrong with them (as they have their own gangs of fan boys!!!), either. I just like my B&Ws.
Some day, when I win the lottery....
