Easier? That's an understatement. Even an SUV has no more space than a walk-in closet. You better be prepared to spend a ton of money to get that kind of bass output and pressurization in a room. LOL
And that Paradigm DSP-3100? It's most likely going to have less output than the PB-1000.
You might want to peruse this database: http://www.data-bass.com/systems. Look at the Rythmik, PSA, SVS, and Outlaw Audio subs. I think these are 2m ground plane measurements. Click on the sub name to go to a page that links to more measurements.
