Thanks for the response... I don't need a ton of features, looking at the Marantz now it seems to have everything that I would use. The main question is the power, I would like to be able to blast these things and not worry about the receiver not having the power to supply. The room I am in is about 30 feet by 15 feet, straight rectangle. And do you think dual subs is going to make a difference worth that much extra money in this size space?
