In my limited experience the Krell Resolution 3 is the most dynamic monitor i have personally auditioned and has very good bass. (updated nodel is the Krell Res 4) That being said it is still a monitor with limited extension and you have a large room, so it will sound as such. What are you trying to accomplish? Do you have a sub?
