Room is 14' wide at the front. The front row, with the 2 chairs, viewing is 7' and change from the screen. The 2nd row, viewing from the first couch, is 11' and change from the front of the screen. Viewing from the third row is about 16'.
Viewing looks really good from either of the two couches. I prefer the front row, of course, where its total imersion. Because of the angles of the chairs in the front row, its definitely like seating in the front row corners of a movie theater in those two front seats.
The lens is 13'4" from the front of the screen. The cabinet is about 3' deep and the screen is currently mounted in front of the cabinet, rather than inset, and that is giving me a shorter throw ratio than I would like.
My throw ratio is currently at 1.6875 which causes a little bit of distortion, somewhat noticeable with a grid up but not at all noticeable with any kind of image on the screen. When I get my cabinet completed I am going to have it inset into the cabinet and hope to gain over a 1' more.
I contemplated tweaking the mount some to gain more throw, but have determined that its really not necessary at this point. Its good enough to hold me over until I get the cabinet finished.
The RS1 is plenty bright enough to fill the screen, with room to spare, in normal lamp. Like I mentioned earlier, sometimes its a little too bright for me, still.
