Power corresponds to the size of the column itself. "Wow" in this regard, do not wait. For a room 18 sq. M. with disgusting soundproofing in the apartment is enough . that's it. I do not recommend the product. Even for $99 you can find something worthy, but only if you are not interested in creating a "smart" home (I can't say anything about it). The photo shows proof that I have it, at least.
