This picture is from a home theater we have in progress in Austin, TX.  We started with an empty room and added a 105in fixed frame home theater screen.  We then added two tower speakers up front.  All speaker wiring was ran through the walls and attic to provide a seem less very clean installation.  In the rear of the room we  ceiling mounted a HD home theater projector with HDMI ran through the attic back to a Onkyo surround sound receiver, Sony WiFi Blu Ray, and HD cable box. The rear speakers are flush mounted into the ceiling giving this home theater full surround sound and a modern look.
