I have my 150 mounted up near the ceiling above my screen angeled down right at me. It is mounted to a board that spans a couple of pillers that go from a 3 foot knee wall to the ceiling. It is backed up by the wide open space of the entry way of my split foyer. Myself I can't belive how good it sounds there. I have it crossed at 90Hz and sometimes I hear very low bass comming from it. Very full sounding. Also very clear.
