Dean, Thank you kindly for your review of your setup as this is invaluable to me at this stage. Sounds like you are very happy with your Dalite. Did you A-B the Dalite with the Stewart Cinema perf?? If you did, was the image so close in comparison that the cost of the screen was the deciding factor? What are your thoughts comparing the Dalite to the cinema perf?
Lee: I hope this doesn't confuse you,
First, my projector is the Dukane 9015,mated with the ISCO. Together they measure at 18inch. (1.5ft)
Second, I would like a 120inch wide 16:9 (10ft wide[not 10ft diag])perf if possibe
Now the proposed calculations: Given Mark Foster's recommendations of 3.5 times the image height (67.5inch) this would yield a throw distance of 236inch. Now add the length of the 9015/isco yields 254inch(21ft). So, it appears I require a total of 21ft of space between the screen and the back of the 9015 to be able to use a 10ft screen.
I don't have a dedicated room for this HT, So I'm using my family room.
The distance between the front wall (where the screen will go) and the rear wall (back of sofa) is 224inch (18.7ft). Looks like I'm just over 2ft short. I havent foregotten the required space for the front speakers-fortunately, I have three evenly spaced large art nitches BEHIND the front wall where I can house my M&K S-150's flush with the wall!
Our viewing position while sitting in the sofa to the front wall is 192inch (16ft). Well, maybe I can use the cinema perf!
I don't know how much space between ceiling and second floor-I guess it would be about 12inch?? My ceiling is 10ft tall. I will be using an electric roll-up screen.
Now that I have done this exercise, I see clearly (no pun intended)that I can use the cinema perf. Now my other problem to attack is that throw distance. If I use the 10ft wide screen, just how much pincushing/distortion will I see with the 9015 set at 3.05 times the image height (as apposed to the recommended 3.5)?
I know I can go with a smaller screen......but I already have a big screen TV! http://www.avsforum.com/ubb/wink.gif
Thanx a million.......Jaime
