I can't tell you the exact wattage, but I live in a well-insulated condo and my neighbors (who have a newborn) tell me almost daily to turn the subs down (which is easy to do, there is a dial on the back of the speakers). They do so politely as I told them about my new speakers and gave them my phone number to text any time it's too loud. They say they can only hear the sub-bass, not the highs, and even commented that "they sound great". The sound definitely carries, but if you're watching a movie or TV that's a lot different than slapping hip-hop or other heavy bass music. If I turn the subs dial all the way down, I can keep it at a pretty high volume without disturbing my neighbors.
