iQSE ByBee on the ceiling

I already have 2 ByBee QSE , one under my CD/ DVD Player, one under my integrated amp.  Regarding my iQSE, I never really find a place that really improve the music.  I recently have find that iQSE can be use as room treatment on the floor, wall and ceiling.  I try it on the floor between speakers and listening chair, with surprise.  Then I move it up above at the ceiling.  On the next day, my music is much more with timber, depth, instrument separation, and great stability.  Have you ever experiement iQSE not inside or under a component, but into the room, walls, floor and ceiling, let me know your experience.  Thank you
