It's all about expectations... but you can do it.

I'd say you probably limit yourself to two recliners or a loveseat. So that's one row of seating for two. There won't be room for a second row, IMO. Working from an acoustic perspective, I'd suggest the seats should go about 2/3 back in the room, or putting your ears just over 9 feet from the screen. That leaves about 4 or 4.5 feet behind your chairs. You might get creative with bean bags or stools, but that's going to be tight.

So with a viewing distance of 9 feet, THX would say the screen height should be 1/3 to 1/2 that. So we're talking about a screen height of 36 to 54 inches. I'm a fan of scope, so I always start with that assumption. 36" high means (36 x 2.35 = 84.6) a screen just over 7 feet wide - plus borders. That only leaves 1 ft on either side, which will be a problem for speaker placement unless LCR go below or behind the screen. 54 inches high would make a scope screen wider than your room. So if you want the height, you end up with a 16:9 screen, which is fine, but I think we've shown here that the width will be your limiting dimension. (potentially, the projector will limit, actually - I'll come back to that)

The general wisdom, if I've read correctly, is to avoid sitting in the center of a small room - so keep that in mind, as if you're like me you're still thinking about scope, but just sitting closer. Or actually, going AT (acoustically transparent) and bringing the screen a little closer to you, putting the LCR speakers behind it.

The other thing that's bothering me here is getting away from the surround speakers. If you put them at ear height, they'll end up too close to you, so they'll probably end up a little higher, and a little to the back. In that case, 5.1 would probably be plenty and I wouldn't fool with surround back channels.

I haven't looked too closely at projector specs lately, but with a projector throw of 12 or 13 feet (maybe less) many projectors won't put up a huge image. You'll want to look at the calculators for projectors in your price range and see what they're capable of at those throws.

I don't see why you wouldn't do this, unless only having two seats is a non-starter.

Where's the door in this room? What about windows?

as for floor I highly recommend sub floor Dri Core from HD I am about to install with my HT but I am just starting probably take a while to that stage. You can also carpet tile which you can do it yourself.

HT should be about sound but everyone want the screen as big as possible. I would suggest inwall speakers behide screen since your room is too small to build a false wall. With that you can go with 90+ screen.

First thanks for answer my questions,my room have no windows and the door is in the center of one of the 14' side wall,let me post the equipment I already have for this project:

speakers:I have this http://www.pinnaclespeakers.com/bd1000.html

with http://www.pinnaclespeakers.com/bd600.html

with this sub. http://www.pinnaclespeakers.com/babyboomer.html

I don't have rear speaker yet so how about in ceiling speakers?

AV receiver Yamaha RX-V65 : http://usa.yamaha.com/product_archiv..._u/?mode=model

Samsung Blue Ray DVD

I planing to DIY the screen but if I have to I can buy one and for sure I need read a lot more about screen dimension and scope (not too clear to me)

I don't have a projector yet so I need a suggestion in this topic

For seats I was planing to use 2 rows of a classic cinema chairs but I can live with the Kmart cinema seat (if still available) and bean bags(like this way thanks)

what do you guys think?

tdong: excuse my ignorance,can you explain me more about the sub floor dry core?

Two rows in going to be very tight in a 14' room...but if you are planning for just regular cinema chairs and not couches or recliners, its do able.

As far as a projector goes, there are lots of great options, but we need A: what your expectation are for the projector and B: How much do you think you are willing to spend on the projector.

As far as building a screen VS, buying, either is fine. Building is cheaper and provides more flexibility, buying is more convenient...it basically boils down to that.

As far as Scope vs. Non Scope, with a room that is only 9' wide, I can say with a fair degree of certainty you'll want to go NON scope. I have a 12.5' wide room with a 9' wide (approx) scope screen and sit really close (about 8') and i wouldnt want to go smaller. you've only got 9' total so you'd have to go even less for some clearance on the sides.

This is just my opinion, but Im guessing most people here, if they only had 9' of width to work with are going to go for a 1.78 screen vs. scope.

Dri Core is THIS

since your floor is concrete. to avoid "floor bounce" the sound the subfloor also help with bass and make your room warmer from the concrete.
