The Varro has never been tested, so no one could tell you except maybe the Varro engineers. Based on the specs, versus the PB-2000 Pro, I would expect it to have a bit more mid-bass but not as much deep bass output. That is just speculation, and it's hard to tell. One big shortcoming of the Varro is that there are no physical controls on the sub, so you are totally reliant on the app to set it up. If there is a problem with the app, then the sub may as well be just a big paperweight. I really don't like that design, and I would steer clear of it for that reason alone.
