I am running Forests in a space smaller than yours: 15 x 13 x 8'. Have the speakers along the long wall - no choice. The Forests take a while to break in and intitially I was concerned about LACK of bass so had them ~12" from the wall. If you visit the Totem web site, this is the minimum recommended distance for the Forests. After a few hundred hours, I now have them ~18" from the wall and slightly toed in. I am sitting only 7' away. I don't find them boomy in the least - bass is well controlled (witness Fagen's Morph the Cat). Overall they are very musical and balanced with excellent imaging and detail. FWIW - my amp is a JoLida 502B 60/65W per channel. I don't think you will have any problem enjoying the Forests in your larger space.
