Not sure about the exact distance, but I have the energetic pyramid from Twisted Sage and it certainly exudes palpable energy. Frank is Not My Name, Angelgnome, CE Shawn and others on this forum also have experience with their tools.
Thanks to Sapien’s tools, I don’t have any ghosts or entities in my space, so can’t really vouch for how well these tools work with entities. I remember Brenda from Twisted Sage recommending Wings of Tok for entity related issues. In sessions with her, she seems to frequently use the King’s Chamber within the pyramid to release entities (I understood the significance of this chamber after OM explained the details).

The De-Inhabitor Trio + Curse/Spell Removal Audio and throw in an occasional Deep Aura Cleaning audio, you should be squeaky clean in space, body and mind.
