Abdou arra
Yep, im designing a home theater and I need to know everything, from speaker placement to why should I get it really? EVERYTHING YOU KNOW.
Answer
There are really a lot of considerations to think about. I would start by looking at examples of what others have done. The AVS forum is the place for that... http://www.avsforum.com/avs-vb/forumdisplay.php?s=&daysprune=&f=19
I'll list a few things and leave it to you to do some research...
1. Consider doing a "CIH" system, that is Constant Image Height. For this you need a 2.4:1 or greater aspect screen, video scaling, and an anamorphic lens. I like Prismasonic lenses because they are adjustable. http://www.prismasonic.com/account/order_form.php Movie aspect ratios vary quite a bit so this lens allows you to adjust for this.
2. Consider a curved screen. This can correct for distortions in the lens and can improve brightness uniformity just a little by slightly reducing the maximum off axis viewing angle. Btw, you can build your own screen relatively easily using DaLite material from http://store.cousinsvideo.com/cut-to-size.html
3. Draw the layout of your room, from that determine viewing distances, off axis angles etc. You will need to know all these things for choosing a projector, screen material etc. I used a 1.3 gain material, it's a good solution for most typical dedicated home theatre applications but you need your room drawing to determine if it's right for you.
4. Think about equipment location. You may want to build a control closet attached to the room.
5. Paint the ceiling flat black, you won't be sorry. Also a neutral gray is good for the walls but it needs to be very flat. Also don't hang glass covered movie posters on the walls in your theatre, these belong outside in your theater lobby area.
6. You can use a Receiver if you go with a high end one but I would suggest using external amplification for the main LCR channels. A lot of people argue this isn't necessary but I've always found it to sound better. Your best approach is not to use a receiver but a preamp processor. The advantage of the receiver is that it eliminates the need for external amplification of the surround channels. Usually the receivers built in amps are good enough for surrounds so it's a convenient package to have all that built in. It is still a compromise over going with a preamp processor however.
7. I don't know what to tell you on speakers. I've been building my own since the mid 1970's, actually early mid 1960's if you count mounting old TV speakers in card board boxes when I was about 6 years old. After so many years experience and the good fortune of influence by many speaker designers far smarter than me, I simply can't get excited about any of the commercially available speaker systems out there. I can only say don't go too small. If a speaker is operating in a range where it becomes stressed at typical play levels then it's not going to perform very well. Get something capable of far more output than you need and then at least it will have a more "effortless" or "easy of delivery" sound. Some people use commercial cinema speakers in their home theatre. While these don't produce the most refined or musical sound in my opinion they can certainly be a lot better than a lot of the mass market non sense out there.
When I was developing my theatre I did a lot of googling. I would just type in "Home Theatre" and click "Images" or sometimes just a normal web search. I looked at every example I could find! I had never head of an anamorphic lens before at that time. Before any ground was broken for the house the theater evolved from a combination game room/theatre with a 100" 16:9 screen to a totally dedicated theatre with stadium seating using Berkline electric recliners, a 144" 2.4:1 42' radius curved screen with anamorphic lens... So google away and find every example you can!
Edit: Grumpy Mac, I think you have Abdou wrong. His previous questions do not suggest he is a troll. His answers are short an to the point... too short in fact usually 2 or 3 words. I think just not a man of many words! Abdou, it really would help if you told us more of your plans. Of course when I started dreaming up my system I could not place a fixed budget on it. I didn't know enough about what I wanted to know what budget to put on it. I ended up spending almost $50K and I'm still going.
If I had put that number on it up front I wouldn't have let myself start. So I can understand if you don't know what budget to place on it but we really do need to know at least some idea. Also not just budget but more about room size plans, dedicated room or not... etc etc etc...

http://www.amazon.co.uk/Sony-VPL-HW15-Full-Projector-60000/dp/B002PLLZKG/ref=sr_1_3?ie=UTF8&qid=1288306399&sr=8-3
Is it any good, ? we dont want to spend to much and also i have found this screen, :
http://www.amazon.co.uk/PCW106GE-Projector-Screen-Glass-Beaded/dp/B0026RO1OG/ref=sr_1_3?ie=UTF8&qid=1288307315&sr=8-3
so can you tell me what else i need and are these screen's and projector's any good and if not can you tell me some other good onces thank you please help !! ???
Answer
There are a number of things you should consider when designing a home theater system and doing it right. First thing is figuring out the best layout of the room, for acoustics and seating. If you have attic access to the room then it will be no problem pulling wires to where you need them but if you don't then you should strongly consider getting all the necessary cabling, electrical, and venting you will need. Ideally its nice to have a equipment room off the main theater, but you will need to have easy access to this room to load your software. You want to make sure you have adequate power and ventilation to dissipate heat generated from the equipment. You will need cable or Satellite, and internet pulled to this location as well. Then there is speaker and video cables pulled from the equipment room to the where your going to have your speakers and projector. You will also want a cat5 cable pulled to the front location to control the system from your remote control.
Also don't forget power to your projector as well. So there is a number of things to consider and anyone one of these that are not prewired before drywall is closed will compromise the use of the system.
When pulling power to all locations make sure you pull dedicated 15 amp lines all pulled from one side of the electrical panel as this will assure proper phasing and eliminate any potential ground loop issues. Another nice option is instead of running speaker and video cables to the locations is to run 3 inch plastic conduit so you can pull or change out your own cables as needed.
As far as the projector and screen, the projector is pretty good, there are better options at this price. As for the screen this is not a good screen, the screen makes a big difference in the picture quality so do not underestimate the importance of the screen. You will also want to choose the best size and aspect ratio for the sitting distance and projector.
Stewart Film screens & Da-lite are making the best screens right now. I prefer Stewart Film screens my self and use them exclusively in all my home theater projects. Right now the hot setup is doing the 2:35 to 1 aspect ratio screens so that you can display all the wider aspect ratio movies in full screen. This will require masking for standard 1:78 to 1 and 4:3. This can be accomplished with motorized masking or curtains.
As for projectors, you can certainly get some good information from Projector Central. Runco, JVC, Panasonic, & Barco, I feel are making the best projectors right now. The Sony model you mentioned is not bad but I favor this manufactures for resolution and service.
I would strongly suggest going to your local independent hi-end audio video store as they carry the better brands of equipment and can help you design and choose the right equipment for you room and budget. You can also get some good information from some of the better trade magazines like Perfect Vision, Stereophile, and Widescreen Review. I have also written articles which you might find helpful your welcome to read especially in choosing speakers.
