Hi all,\n\nI am planning to build a dedicated HT with a 7.2.4 setup. My room size is 21 ft x 15 ft x 9 ft. I will use the room for movies, music and games (33% each)\n\nMy final components are as follows:\n\n Projector JVC DLA NX7 \n Screen Elite AR150H2-AUHD \/ Elite AR135H2-AUHD\n Receiver Marantz 8012 \n Power Amp Emotiva XPA-3 Gen 3 \n Woofers (x2) Rythmik F18\n Speakers LCR B&W CT 7.3 LCRS \n Speakers Surrounds B&W CWM 7.5 \n Speakers Atmos B&W CCM 684 \n\nAs we can see, I am confused between going for a 135 inch or a 150 inch screen. What would be the ideal viewing distance for both the sizes. I have researched quite a bit on this and have found varying opinions. I was thinking of going for 11 feet for the 135 inch and 12 feet for the 150 inch. Would that be too close\/far? Kindly help thanks!
