B&W ASW 300 Subwoofer

I'm looking for a basic system for my bedroom and plan on a set of bookshelves and a small sub. I'm quite interested in the 300, but my local dealer has none in stock. Anyone have anything good or bad to say about these? It looks to be quite a long throw driver but I'm not expecting room shaking bass from an 8" driver. Thanks in advance

I have the B&W ASW 675, and it is a wonderful sub, if the 300 is half the sub as the 675 is should be great in a bedroom provided the room is not to large. Good luck.
