MartinLogan Dynamo 1000 or B&W ASW 675 - Newbie Needs Help


I have a chance to purchase a couple different subwoofers to add to my home theater, and I am fairly new to all of it, so I was hoping to get a little help. The MartinLogan Dynamo 1000 seems like a great speaker from everything that I am reading, but I can say the same thing about the Bowers & Wilkins ASW 675. It is going to be primarily used for watching movies as part of my other surround system and for listening to music at times. I can grab the AWS 675 for $200.00 and the Dynamo 1000 for about $175.00, which I think is a deal for either one. I enjoy a lot of thump and bass, and I just can't decide which one to get of the two. 


Looking forward to learning from all of you.

I've got the Dynamo 750 wireless and sealed with wireless connect.
Never expected it to be as tight as it is with fairly large output in such a small enclosure. I would think the 1000 would be about the same with more output though.
