Hi All,
Today I was playing around with the Submersive and have it sounding pretty darned good without touching REW or my DSP-30. I decided to listen to a Tom Petty concert I had saved on my DVR (when he was live in Florida on Soundstage). The impact of this sub literally gives my wife goosebumps. I saw something moving around the sub and thought it was a rat or something but it wasn't. It was the speaker cover

Check out the quicktime file. Not as impressive as real life due to the low resolution but you get the point. I want another one......
