I had both 9040's and 9080's. I think with the 9040's yes you could use more bass. The 9080's had enough for my taste in my room. That's the thing, all depends on what you like and how your speakers sound in your environment. That said, I was not super impressed with the supercube. I do love the DT speakers. But did not getin my opinion big bass by adding the supercube so I took it back.
