Home cinema ideas for a room 5m x 3.3m

Hi all, I am after some basic information around my plans for a small home cinema in a house I am looking to buy. I always wanted a home cinema but other things took priority. The house we are looking at has a wasted space behind the garage 4mx3.5m roughly and I wondered what I need to consider with a room this size.

I would be looking at erecting either a brick extension on the back of the garage or one of these, certainly not a shed as it is fully insulated, electric connections, network connections, sound proofing, underfloor heating etc

It would be a rectangular room with a sofa one end, projector mounted to the ceiling and then a screen at the other end. Somewhere to relax watching a film/football and the odd gaming session. I will want to connect a macmini/pc and xbox one to them as a minimum.

Firstly what sort of projector do I need to look at, is there anything specific to look out for based on the size of the room?

What sort of size screen could I have?

If we end up buying the house I will be asking for more advice around audio and source info but for now I want to get to know projectors. No real budget in mind as yet.

Thanks in advance

Thats a very closer to square than rectangle room. You would need to be really mindful of standing waves and the hideous bass problems it can cause. Youre always going to have standing waves but in a square room its really bad. You could try and cancel it out with a sub in each corner but the rooms small and you might want space. If you can I would add an extra 0.5m onto the 4m wall.

In terms of projector, that would be one of the last things I would look at, after I have worked out positioning of seats, speakers and if youre properly serious acoustic treatment.
 
So interms of the room shape, I think there is around an additional 0.5m I can add to the length of the room as it will be a custom build, either brick or wooden structure, the rooms only purpose is a cinema room so not got to worry about use of space inside as it can be setup to best suit that need.

I will be looking into the sound deadening options, I know as standard they have double glazing, roof, floor and wall insulation with 44mm double wall.

So are we saying that a room 4-4.5m long is plenty big enough for a projector setup. Can anyone point me to a decent purchase guide for projectors so I can start reading up, are there any particular brands to avoid?

Close to a square and being a square are two different things, as is how low frequencies will act within a home theater system utilising small speakers with a single subwoofer versus a pair of large speakers in stereo.

I think the OP will be fine with a sub/sat package and carefull placement and soft furnishings or even a bass trap or two in a corner.

As for your comment of a projector being the last thing he should look at!

WHAT ARE YOU ON?

He wants to build a small media/entertainment room within a 4m by 3.5mm plot in his backyard for that exact purpose.

OP.
My advice would be to look at 1080p projector reviews and aim for a fixed screen if possible up to 80". But only once you know what image size your chosen projector can manage in your chosen location. So look at projectors, the distance your projecting to, calculate height and width, and if your ceiling is too low and it falls bellow an 80" screen size, consider a large sceen TV instead.

Your main blank wall is C by the looks of it, at 4m your looking at 2m width as you try to maintain a reasonable distance with your left and right channel speakers from side walls, is that the wall you plan to have a screen on?

From past memory, I remember a similar sized room and the best image size available with the projectors throw was only 70". By the time you consider the cost of a 1080p projector, and decent 70" screen and cableing, your getting into 60+" 4K tv territory.

A collegue and I have a huge cinema set up in an industrial warehouse, within an 80ft odd workshop, 7.2. My bedroom also has had two projectors within it's history, I still have an old 720p and 80" screen for occasinal fun in storage, as I stopped using a projector in any situation under 80". In future I plan to simply buy a 60+" 4k tv for any install where the stereo fronts are 2m apart.

I like a 2m minimal distance between L&R speakers, and with a satelite speaker system you can get a reasonable balance of speaker spacing and still use an 80" screen. But also remember to consider ceiling height, overall cost, and convenience!

Edit. What budget do you have in mind for said projector and screen? A simple google search throws up many top 5 and top 10 projectors, but cost varies. As does a decent screen. What resolution are you after? I state 1080 simply because of price and available material, I still have a 720p because with much material on an 80" screen it simply still looks good, and we did upgrade to the 1080p variant at work, then an even better 1080p which I cannot even remember the model number of. The majority of my 720p content came from games consoles and Tivo, hence it still being viable, but for movies BluRay is still top dog at 1080p. 4k content is practically non existant and a gimick so far, but may well change in future hence my TV recomendations.

It makes perfect sense, to first think about seating position and placement of speakers and acoustic treatment of the room in terms of how this can massively effect the quality of the sound. The size and position of the projector will not give him half as much problem as the sound will. Thats not to mention he shouldnt research it, by all means research everything but the biggest problem I see which is glowing to me is the room dimensions and how vulnerable sound can be to its environment. And he will have standing waves in that room, which will be very hard to treat with just some bass traps due to the low long frequency and that he doesnt have much space.

I agree with the satellite speaker system but that doesnt mean you shouldnt demo other speaker packages and also give some thought to what you may want to upgrade to in the future
 
In terms of source, it will be my xbox one, MacMini , blue ray films and Sky HD box.

Layout wise, please ignore the crudeness of the diagram below but gives you an idea of the layout I was thinking about, subject to change of course as I may go for a larger sofa.

Budget for projector lets say £1000 but can be flexible if needs be as not really sure how much the cost is for the average projector.
 
As a side question that may well help the OP anyway; you can now get 1080p 3D DLP projectors for less than £500 when previously they would be over £1k. What truly separates these sub £500 PJ's from one costing £1500 right now?
 
At 3.5m I had a 120" screen at my old place. 16:9 content was perfect, but if anything scope movies could have been bigger. Go for ~120" if your chosen pj/screen combo can power something that size. PJ wise I'd stretch for a JVC or Sony - doesn't have to be this gen - if possible. The latter if you're leaning in favour of gaming, a JVC if in favour of movies. If budget is a concern I'd get the best pj you can justify and paint a cheap screen on the wall. Infact, I suggest going that route anyway as buying a screen and pj at the same time is always a mistake, imho. A screen you can always add later and this is the important purchase you want to get right. pjs come and go - a good screen will last you forever.

Can you treat the room at all? This will make more difference to picture quality than pretty much anything else. I'd rather have a 1k pj in a treated room than a 3k projector in something more standard, for example. Dark carpet, walls, ceiling etc. Black velvet panels coming out from the screen on the walls and ceiling for a meter or two looks smart as hell, can be cheap, and makes a big difference. You've got a nice space to fill there mate - go crazy with it :)

Budget is very flexible so yes I can do what I like to the room, when you say treat it I can choose the finish in the room, I can request dark floors and a plastered finish to the interior. I can then paint and decorate as I wish.

Is the suggest that dark colours across the entire room and black out blinds for the door and any windows?
 
Pretty much. I ended up painting the inside of the door, door handles, radiator etc black. It actually looks very cool when all done and it all helps. Dark furniture too. Even putting tape over the leds on your av equipment will make a difference - it all depends how anal you want to get about it :)

One thing that's very easy and effective is wrapping black velvet around foamboards and sticking them to the ceiling and walls coming out from the screen. I dabbled with this at my last place the difference was considerable. You can see the beginnings of it here: http://forums.overclockers.co.uk/showpost.php?p=28882684&postcount=8 A few meters out is plenty. In my next place the entire room will be done!

Treating the room was actually my favourite part of the whole project. Seeing the picture coming more alive with each change is very satisfying.
 
How high is your ceiling, and will you be shrouding the projector? Light bleed, noise and heat can be noticeable when it is above you.

One of the reasons I did not state a 120" screen is simply because it shoves your speakers into corners and may actually put too much light into the ceiling.

As someone else stated, it is worth trying to get the projector running within the room, and seeing what sizes of image suit the layout. I too advise dark colours and non reflective too. Especially on the screen wall. But painting a screen, well it can be ok if you have a flat surface, our screen area at work was too large and outwith our budget, but we did have a plasterer do an exeptional job on the wall and painted it, but no one I know sees paint as a substitute for dedicated screen material. We also use huge black velvet panels from floor to ceiling to mask reflections, but the ceiling and floor are still highlighted by the light from the projector.

I also recommend having the seating further forward.
 
Get some panels on the ceiling, sastusbulbas :) They're the ones that made the biggest difference for me. My last screen was under a foot from the ceiling but the panels sorted any reflection issues. Re. a painted screen - if you're careful sanding things down then the results won't be far off cheap paid for option. The flexibility of being able to play with different sizes more than makes up for it. PLay around with sizes and give the bulb a chance to dim over a few months and then settle on a decent fixed frame jobbie.
 
What are you on?

It makes perfect sense.

No, it makes no sense to put the projector last when deciding to make a dedicated space for using a projector.

But then again, it makes no sense when it's with regard to a possible room that may get built and we are all just generalizing.

And room dimensions need to include height too, also contruction to some degree, you can build the perfect golden ratio shaped room, but with a suspended chipboard floor, stud partition walls and a suspended tile ceiling your still going to have issues.

Bass nodes, well it really depends on what he actually installs does it not, and how much freedom there will be with speaker choice. The fact that there is already talk of 120" screens on a 3.5m wall without even discussing ceiling height or speaker choice and placement tells us all we are jumping in too quickly anyway.
 
Get some panels on the ceiling, sastusbulbas :)

Our system at work is a little more complicated, as the room has a suspended tiled ceiling fitted which is lower than we would like. And the majority of the set up is mobile.

We have recently dropped to smaller speakers though, previously we used cerwin Vega V-152's but have now moved to JBL JRX112M pole mounted for the rears, JBL JRX225 for L&R and a pair of JRX215 wired parallel for front, using a Denon DN-500AV processor with five Yamaha stereo power amps for a 7.2 speaker set up. Subs are just DIY, with another project having been on hold for a few years.

But this all has to be portable as the room is in constant use through the day, seven days a week. and we only set up occasionally for movie nights. We do have the room cabled for the set up, we just wheel it all in, plug it up and away we go.

Edit, it did start as a beer budget set up for two men who last their home cinema set ups after having families, hence the eclectic mix of kit, but due to the size of the room, speaker size had been an issue, hence the choices.

Optical quality, size of lens (light throughput), real contrast ratio, ability to focus more evenly across the screen, less drift of focus as the projector warms up, better video processing and motion handling, the type and composition of the colour wheel and whether it is designed for brightness or colour saturation and accuracy. There's also things such as the colour wheel speed which is also linked to the capabilities of the driver technology that "writes" the image to the chip. These are just the things I can think of off the top of my head and I haven't even touched on fan noise, light leakage, software and whether the projector has CMS etc etc.

Single chip DLP projectors span a price range from around £300 to £20,000+ (yes, a two followed by four noughts), so projectors in the £500-£1,500 price range are in very much the shallow end of the pool, but that's not a criticism; it simply highlights that not all single chip DLPs are alike. I'd go further and say that while you can have a lot of fun with a sub £500 DLP, upping the budget to £1,000 does deliver an appreciable jump in the potential of the products. For example, until fairly recently Benq's W1070 model has been the entry-level product of choice for first time projector buyers simply because their low prices made them very accessible. It came in around £600-£700 when most home cinema projectors were over £1,000. The paper spec looked good: bright, 1080p, 3D and even a limited amount of lens shift. All that ticked a lot of boxes for folk. What was harder to convey on a spec sheet though were where the corners had been cut. Most notably that was in the video processing. The projector had limited powers to resolve small moving items.

Somewhere to relax watching a film/football and the odd gaming session. I will want to connect a macmini/pc and xbox one to them as a minimum.
I think that if you're going to the trouble to build a room especially for projection then you should dispense with the idea of a TV altogether and make it a dedicated projection space. You'll have TVs in the house for casual viewing. This space should be something special. It should have a real 'wow!' factor that makes going in there an event in itself. To that end here's what I'd do if given the space...

(1) colour scheme - give this some though before you plan anything. Furniture isn't available in every shade under the sun, so it's much easier to pick the furniture colours first and then use that as a starting point for room colours.

There's value in the screen wall being black as it will deliver the highest contrast with the picture when all the lights are off, but that doesn't mean that the whole room has to be black to match. There are plenty of other matte tones that work almost as well for light absorption and still allow some artistic expression and design pizazz so that even when not in use the room still makes a statement that enhances the property. As examples, look at Dulux colours such as dragon's blood red, venetian crystal or bitter chocolate as a starting point for multi-tonal colour schemes. You could even go with tones of grey.

(2) put in good lighting, and lots of it! When a room is colour designed to absorb stray light then iot will do exactly that with any room lighting you use. Also have a think about some decent light control gear. Something that can handle three or four circuits and be programmes with lighting preset patterns as well as allowing manual override really is a solid investment.

(3) build a false wall and go for a fixed screen on it. The false wall will give you the space to hide the speakers behind the (acoustically transparent) screen or simply behind cloth covered panels beneath the screen so that sound appears magically from the screen itself. The benefits here extend beyond copying what's done in commercial cinemas. The area inside the wall can be lined with foam to become sound absorbing as well as being a useful way to hide some wires. This means the front speakers will have an easier job of producing intelligable sound and so you can (if needed) dial back the speaker budget a little. It also allows you to go for a larger screen.

(4) spec a projector with the right sort of throw ratio that will do 21:9 and 16:9 in your room; then spec a 21:9 screen to match it.

From the description you'd like the room to fulfil a few different roles: Gaming, TV viewing, streaming and serious film viewing. When doing the first three on that list the image will be 16:9 in most cases. Sometime the image quality will be great. At other times it will be less than stellar. Your consistently best quality image will be Blu-ray movies. But when watching films on a 16:9 screen you'll lose part of the screen area above and below to the black bars. This means your best quality source ends up giving the smallest picture, and your lowest quality sources give the biggest picture. That's a bit backwards when you think about it. Projectors have zoom lenses; they can reduce or enlarge the picture from a fixed position (such as a ceiling mount). This means that you could have the projector zoom up Blu-ray to the biggest screen size the room and throw will allow, and then zoom down for sports viewing, TV and gaming where the more compact image concentrates the light more so that you can run with some room light on, and the smaller image is more forgiving of poorer quality sources, and your gaming experience is enhanced because you're not trying to take in a 3m wide view when playing CoD or GT6. The other thing is that 21:9 screens just look so damned cool. Every house has 16:9 tellies. How many people do you know with a 21:9 cinemascope image?

(5) add some device to control everything (or as much as can be controlled) but don't use a tablet.

This is about winning over your partner/wife/significant other and the rest of the household if applicable. While the room might be your domain, very often there's someone else involved in financial decisions of this kind. That's important because when it comes to upgrade time it's much easier to get the green light if the rest of the household have really enjoyed using the space too. The way that happens is by making it so easy that it's foolproof. That means no calls when you're bombing down the motorway "How do I put a film on/watch TV/set up a game for the kids?" Tablets are cool and we all like them and enjoy finding new ways to use them, but despite a plethora of programs and apps promising to be able to control stuff the bottom line is these things are still a bit of a gimmick until you start spending some serious wedge (£1,000+).

There are two other issues. The first is usability. Tablets go to sleep and engage the screen lockout. If you just want to pause the film of change the volume do you really want to unlock the tablet and then make sure it connects to the Wi-Fi and then wake up the app and perhaps even scroll through a couple screens looking for the right control page. Wouldn't it be easier to pick up a remote that controls everything and just hit pause or the volume?

The other issue is the temptation to stay connected with social media etc. You can't check out the news feeds or log in to Facebook or respond to Twitter/Snapchat/WhatsApp because they're all push notification applications that keep nagging for attention.

Handheld system remotes seem like something of an indulgence. Why spend money on yet another remote to do what all the remotes already do that came with the bits of gear? On the face of it that's a difficult thing to argue against, except when you're trying to tell someone over the phone which buttons to press just to watch a movie off Sky. The other common problem they solve is to remedy an attack by the button pushers. These are the times when someone came in to the room, tried to make the system work but failed because they changed all the inputs and settings. One simple press of the remote can cure all that. As a starting point have a look at Harmony remotes. They're relatively inexpensive and have enough power to take care of small to medium sized systems. If you want something more bespoke with a bigger touchscreen area then there are other products on the market.

Youve got an amazing opportunity here to build a brilliant little home cinema. Most people are stuck with the room that is already built and have to work around barriers to the best setup. I know youve only just started to look at this but if you can move that seating position off the rear wall as bass will accumulate there. Some people advise about an equilateral triangle from the main speakers. Also there is a theoretical 38% rule from the rear or front wall for the best listening position. Once you think you have that roughly figured out put some thought into where the first reflection points of the speakers are. This is where the sound bouncers of the side walls and reflects back to the person and can really distort the sound. Then you want to put some acoustic treatment in that spot which I personally have heard to make average stereos sound amazing.

If you are aiming for the best cinema experience you can acoustically treat your room for not much if its a DIY job using rock wool slabs for broadband absorbers or using wood for sound diffusers. A really nice projector is great but the sound is what really immerses a person into the film.

EDIT:

No, it makes no sense to put the projector last when deciding to make a dedicated space for using a projector.

Just read your post, which I completely agree with. There are so many factors to take into consideration but I still think acoustic properties of the room is a big starting point. You get the room right, it will save a lot of bother down the road when choosing what to install in it.

This picture is from the website of the installer that I'm going with for my cinema room and may give a few ideas for your room too.

I think the pelmet running round the top corner of the room allows for some good lighting design with down lights and an LED strip running round the edge to add the wow factor. It also provides a good discreet place to put the projector.

My room should be done by end of January so I'll be posting some pictures of it on here, but it's going to look similar to this picture.
