You currently have a small listening room well suited to the Totem 1 speakers. They may be short on bass but should sound great in that setting with proper amplification, which you have. Most people who know Totems would probably say it's too much speaker for your room. For that reason, I would say adding a fast, high quality subwoofer would be the safest upgrade path for where you live now. That said, there may be integration issues and adding more bass with either the Forest or subwoofer may bother your neighbors. But at least with a subwoofer, you can control the volume or turn off if late at night.
Good luck from a Totem owner.
