The sub reminds me of some of Def Tech (like the 6000), however, the Martin Logan is much less expensive.
I like the remote on the Dynamo.
I know this thread is about a year old now, but I just picked up a new one for $545.00 plus tax. I think I got a great deal. It helps that I work with one of their (Audivisions) old (and respected) employees. And got 2- Motion 15's for $655.00 plus tax. The dynamo sounds fantastic. Wish it had a remote though.
