My basement recreation room is:

22'9" long, 10'6" wide, and 7'4" high.

As you can see, it is long narrow, and the ceiling is a little bit low. I am thinking of putting seating in like this








Do you think a DIY projector would be workable in this amount of space? Could it be ceiling mounted? I was thinking of a screen maybe 72' x 54" or 80" x 60 ".
I am thinking of using chesterfields rather than armchairs because if there is a single person watching they could sit in the middle. The width of the room only seems to allow for two arm chairs side by side which would mean no one could ever sit straight on in the middle. I would be interested in hearing from anybody to tell me if this is looking feasable, ar any advice you would like to give me.

Thank you,

Where would you projector be? seems like with that room height you would have projector only 8-9 feet from screen. and to low for ceiling mount and you would need your projector in the center of room.

Either of those screen sizes, means the projector will be 7-8 feet from the screen. That is a little too close, do you agree?

The projector can naturally be ceiling mounted. I would first, set my screen as high as it can go (a few inches from the ceiling). This reduces the amount of down angle you will need on the projector. Second, I would get a real good idea of the line of sight for the rear seats. You would want to hang the projector as low as possible, once again to reduce the amount of keystoning you will need to do, but you don't want it interfering with the view from the rear seats.

But I don't think you are going to have the projector back far enough to stay out of view (or are you waiting on the zoom lens?). If you are going to be using the standard optics, available now, I'd reccomend using a larger 16.9 screen, and having the projector on a track perhaps, so for those instances in which you really really have to use 4.3 ratio, you can slide the projector on the track and get a small image that will fit entirely on the screen. (Wow, 60+ words in one sentence.)

Are you a Lumenlab customer? Ah first post, joined up today eh? Welcome! You will get more responses I think from one of the member only forums (aka Help).

I have lots more info/ideas/suggestions, but I've no time.

Later.

How dare you post before I do? Now I have to recheck my math to see if my numbers add up, as we got different answers.

funny, don't forget he's talking about height not width of screen for the 1:1 ratio..

ttfn, Joe

Here's my standard answer for long rooms; put the projector in a box between the first 2 seats such as this:

i agree,
i have mine floor mounted and it is really nice.

ok who took a picture of my movie room??????

Oh, BTW don't forget to vent the fan exhaust of you will get complaints from the back row. you can just vent it under the rear riser section with no problem.

With a room that long, would it not be a better idea to rear project the image on to the screen? I know that means a specialised screen material, but it would solve all the positioning problems.

Well the room's only 20' and with the standard optics you'd need 10' of throw for a 10' image. So by rear projecting you'd use half of the room.

Brain, Chevy's got us confused. That 1:1 ratio is for the diagonal? (Sounds like he was trying to say it was for the height in an earlier post.)

It is for the diagonal.

I paid the fee and joined up to LumenLabs. Thank you for the responses. I think I get the idea about the room and checked the 30 to 35 deg THX viewing angles and I am pretty sure that the room will be OK. I think I can go bigger, maybe even a 96" x 54". The PJ would go down low in front.

I am getting my bearings here as to how the HT all hangs together. So far I am under the impression that the DIY PJ needs to be fed from some type of TV box such as a Viewsonic N6 or a Kworld or a PC with an All-In-Wonder Video card. Is that right?

I am not sure how it would all hook together. My sources will be

1) VHS VCR
2) DVD player (I will be buying a new one)
3) Cable TV provider ( it is a regular analogue cable service but I would want the HT setup to be ready for the future when the Cable service switches over to all Digital. They do offer digital TV now, I just don't want to spend the extra money for it yet).
4) maybe a Sony Playstation 2


Lets assume I get the N6 box going to an LCD panel. Is the following illustration correct? Maybe the DVD and the VCR are supposed to go to the receiver first, then there would be just one cable to the N6? If I am buying a new DVD player then what output would I be looking for? My VHS VCR has a coax ouput and the RCA Red/White Audio Out with the RCA Yellow Video Out.

You definitely want component on the DVD player. The lcd panel has VGA input (computer monitor). In your illustration your DVD would connect to the N6 with the component hookup. The VCR with composite or svid. The cable into the N6 coax. The Playstation can be svid, composite or component with component being the best choice, but you will need a PS2 to component adapter.

OK so the Cable coax goes straight to the N6 therefore the N6 must have an audio out, correct? I changed my drawing - does it look correct now?

Thank you,

Dwight

couldn't you just throw one of these on before the N6 ?

N6 has audio out.
