I have a 2 year old house with a 21' X 17' X 10'h dedicated theater room on the second floor, painted black including the ceiling, with no windows, sound proofed walls ceiling and floor with two rows of 4 seats with head rests at 12' and 17' from the front wall, with the back row raised 14". I had a custom installer wire my room and connect my old acoustic research high res AR-3 front speakers, surrounds and sub, mounted in a 7.1 channel set up. They are connected to a Yamaha RX-V2400 7.1 receiver which claims around 130 watts x 7 channels. I would like to ceiling mount a 1080p DLP projector behind my back row, maybe at 18' or 19' from the front wall. Also I'd like to use a 110" or larger fixed or possibly a masking type screen. I stopped on my theater because of cost over runs on my house, but I am now ready to finish it. My previous installer wants to finish up with an Optoma HD-81 or Sim2 D80, a 110" or 123" Luxus Deluxe Stewart Firehawk, and a Toshiba HD dvd player. The reviews on the Optoma have revealed several problems including high noise level and the green or blue screen of death on occasion. I am open to any suggestions on projector, screen type and size, HD/Blue ray DVD player and anything else, but would like to keep the projector behind me. My budget for the equipment is around $15k. Any comments are welcome.
