I received my new Captivator S2 last week and I am blown away. Earth crushing, powerful, tight. And I currently own dual Seaton Submersive HP+. I am using the Dspeaker Anti mode 8033S-II which has tightened up the bass appreciably. My room is 14'x25'. I am in bass heaven!
If you are on the fence about purchasing the S2 let me tell you that this thing is incredibly well made, like a bank vault. Imagine sitting right next to a car falling into your movie room and you get the idea of the sheer impact it produces.
One thing I do notice is that I get a lot more vibration into my kitchen below. Not sure if this is due to the higher output or if it is due to the fact that the Seaton's have the dual 15" opposed woofer design that cancels out vibration transfer though my floor.
I will try some of the Subdude type isolation platforms to see if that helps. Wife is not thrilled that her kitchen feels like it is under siege from giants during guy movie night.
