This is my first post to this forum. I have been lurking here for weeks and the information provided here has been very helpful in designing and building my home theater. Thank you for all the info. I still have a few questions. First of all, a description of my theater. I am finishing my basement and the dimensions are 13’ wide by 14’ deep, plus an entryway. I have put in the sub floor, framed out the walls, run all the speaker wires and put up the sheet rock. I have not started the spackling yet. I have already purchased the sound system. A Yamaha 5740 receiver with a JBL SCS160SI 6.1 speaker system is including an 8” subwoofer. 1. I am planning to purchase (thanks to this forum) an Infocus 4805 projector. I already ran a s-video cable for it through the walls and ceiling. After my wife spent 3 hours in BestBuy black Friday checkout line, I found that my receiver does not have a s-video output. Only the standard video output. I can get an adapter. Will the adapter work fine, or should I run new wire? I can take down the sheet rock before I finish the walls to do it, but I would rather not. 2. I also already ran the subwoofer wire using standard speaker wire. Will attaching the RCA plugs to the standard speaker wire work for the LFE connection? 3. The 14’ room depth is a little small. How close can, I sit before I get the “screen-door” effect? Will making the screen size smaller help? 4. I am in fear of the “rainbow” effect. I always have to set my computer monitors refresh rate to 85 hertz so I don’t see the screen flickering. There are no stores with-in 2 hours of home that I can preview any projector. Do you think I will see the rainbow effect? 5. I already own a Sony 12” subwoofer. Is there any advantage to using 2 subwoofers? If not, I would keep the other upstairs with my stereo. The JBL has an 8” facing down and the Sony has a 12” facing forward. Thank you again for all your help.
