Well, I have had my Rumba for a couple days now, and I am very impressed. I have a huge room, and when combined with my MTX SW1212, it really fills the room. The MTX has quite a bit of upper and mid bass, but completely lacks the really low stuff, that's where the Rumba kicks in. The two together really compliment each other well. The do a really nice job of pressurizing the room. For the first time I can say that I could feel the bass. I am definitely going to buy another one as soon as I can afford it. You know what they say, two is better than one.
