From all the research I have done, there is no place where the actual wattage of the Sonos products are listed officially. The only comparison I can give you is related to the Sonos Play Bar. I had a Samsung Atmos sound bar with surround sound, which was rated at 500 watts. My Sonos Play Bar gets a little bit louder. Now, that doesn't necessarily mean that it is more than 500 watts, because there are other factors that can make it a bit louder than just wattage. But if I had to guess, I would guess that the Sonos Play Bar is close to 500 watts total, and the sub is probably in the 50-100 watt range.
