Hi, I am wondering how you like the Dynamo subwoofers. Are these the original ones that can be changed to fire downward or out the front? I'm asking because I am thinking about buying one of those on Ebay. I like the fact that it has speaker level inputs. I've seen lots of good reviews, but I'm a little worried that being so old, it wouldn't be able to keep up with my modern ML tower speakers. I like to listen to fast music and I like to listen loud. What do you think?
