In the building process at the moment and currently speccing the HT room.
The room we have for HT use is 6m X 4m, in a room this size would you recommend placing the screen along the 4m wall or the 6m wall and what size screen would you recommend in a room this size? (Keep in mind the doors leading into the room are along one of the 4m walls).

My HT room is approximately the same size - you definitely will want to put your tv/projector screen along the 4m wall.
If you put the screen on the 6m wall, by the time you set up your entertainment unit with TV, and put a nice comfy couch opposite it, you're barely 2.5m away from the screen.
In my setup, even with the couch as far away from the 4m screen wall as I can get it, I still reckon it's too close

If you are sitting at/near the back of the room, say 5-6 metres away you could comfortably go a 120" 16:9 screen.

We haven't moved in yet so at the moment it's just a bare plaster wall waiting to be painted.
I have a motorised 120" screen from my last house, but I'm thinking this time I'll make it almost the entire width of the wall - when we move in, I'll setup some chairs and the projector and spend a few weeks adjusting sizes before decided on what size screen. That way you get a real-life experiment of what works for you and what doesn't, rather than deciding/buying on your projector screen before the room is done, and finding it's too large/too small
... not that "too large" is in my vocabulary

You need to remember to leave enough room either side of the screen to allow for your speakers.
I reckon you already have the right sized screen, and even better that you don't have to spend any more money on it - money that can go into something else in there...

Hi, sorry to hijack your thread but I also have a room that is 5.8m by 4m. I have the TV position on the 4m wall. According to THX or Dobbly standards, they quote rules in terms of angles for both viewing min 26degrees to max 40degrees, and sound approx 25 for front, 100 for side and 135 for back. The problem is I can't fit both viewing and sound at the same time. Should I be going for 5.1 or 7.1 for a room that size? Will a TV that is around 50" be sufficient or should I go larger with projector?

You don't have to completely comply with a standard if it really doesn't work for you (or is physically impossible). Viewing angle would be the last consideration in a room that is longer than it's width, anyway (IMHO).
If you are going to be sitting at or near the back of the room then even a 60" flat panel TV is not big enough for a Home Cinema. You can be looking at a 120" 16:9 screen at that sort of range...

An updated and was hoping to get some advice as we are now ready to start working on the room.
As mentioned above e have a 4m X 6.2m room. Here is the plan of the room to give you an idea where windows placings will be. http://www.globalagencies.com.au/layout ... cinema.jpg (Red and blue lines are markings for walls and opening or walls and doors.
I guess my questions are:
1. We are looking at building a wall to **** the room off. Either 1m wall each side with a 2m opening in the centre to be covered by curtains - sliding doors.
2. Cover the entire wall in and have double doors in the middle.
I guess id like to know what you think the best option would be and based on that where the screen should go.
Thanks in advance.

Hi there Toohey,
Looks like you are going to have a nice space there. 6m x 4 metres is certainly a good space to install a very nice 5.1 or a 7.1 system. I guess the most important question that you need to clarify is whether you want a media room or whether you want a dedicated Home theatre? I media room is more of a multi-purpose room that can be used for TV viewing and movies, music listening etc. If you are after a dedicated Home theatre, that, in my humble opinion, is something totally different and calls for a different approach.
You have cut the rest of the floor plan off so I cannot see what rooms adjoin the media / HT. If they are bedrooms, then soundproofing is going to be of significant importance. If you like to listen to your music / movies loud, again sound isolation should be high on your list of priorities. This is something that can be a bit expensive, depending on the results required, proximity to neighbours, listening habits etc. I see that the room is open now to the hallway? If this is the case, I would recommend that you close the walls in and have just a single door to enter the room. Doors are a major contributor to sound leakage. If you are going to have a door/s, make sure that they are solid core exterior grade doors. Not that much more expensive and will significantly reduce sound leakage from the room. Raven manufactures a range of seals that are inexpensive and quite effective. Available from Bunnings.
If you are interested in good sound isolation, I would recommend that you look at products such as Green Glue Whisper Clips, Green Glue (a product that bonds and reduces sound between double sheets of gyprock) and making sure that all gaps and joins are sealed with an acoustically rated sealant. Sound is like water. It will leak out of any gaps in your room. Double the gyprock will mean extra cost but if done properly, will result in greater control of sound within the room and reduced leakage of sound outside the room.
My guess is that if you are looking at a 5.1 or a 7.1 system, you are planning to run your system fairly loud. That being the case, sound isolation is a must. Happy if you want to PM me and I can point you in the right direction.
Have you considered an acoustically transparent screen? This would mean that you could have the builder fabricate a simple stud wall approx 60cm off the screen wall and then you can mount all of your speakers behind a specially manufactured screen. This allows for a much tidier setup and keeps all of your speakers out of sight. It also gives a more realistic sound / Image combination. The sound appears to come from the picture, rather than from artificial locations as dictated by placing speakers around the screen. Most guys I know manufacture their own screens and simply purchase the material from overseas. There are a number of suppliers here on the Forum that supply high quality screens so worth checking out. Selby Acoustics are one of them. Good products, great service and nice people to deal with. However, should you wish to consider an acoustically transparent set up, PM me and I can point you in the direction of some photos and also suppliers of the material. Building a screen is simply a matter of making a fairly simple braced rectangular frame, stretching the material over it and stapling it to the frame.
With a 4 metre wide wall, you could easily look to go for a cinema scope type arrangement. this would mean that your aspect ratio for the screen would be 2.37:1 rather than 1.78:1 (typical widescreen or more commonly known as 16:9). The 2.37 format will give you a true widescreen experience and need not cost the earth. You can buy projectors now that can give you a cinemascope image without expensive add on lenses. Two examples are the Panasonic PT-AE4000 and the Mitsubishi HC6800/HC7000. There are others as well. I think the BenQ W6000 may have this feature. Rodda may be able to clarify this. I think he may even stock the projector. Most movies that you watch at the cinema are in cinemascope format and this is the format that many blu-rays and DVD's are coming out in. If you intend to watch mainly TV on the screen and gaming, I would suggest just go for a standard 16:9 screen.
Just a few points you may like to consider. Happy to help out more if you like. PM me.

Hey Greg, thanks for your huge reply - a lot of food for thought in there.
I guess you have hit the nail on the head there, i will be using it for Movies and Music so it will probably be a Media Room rather than a dedicated theatre.
The rooms backs onto the passage which backs onto the alfresco and then a few meters before the boundry and neighbours house - biggest worry is if left as it is now the speakers would be angled directly at their house and i dont think a glass sliding door would do much to prevent the noise getting outside. I was hoping a wall and some solid core doors would help with this. Bunnings seem to have Hollow, Semi Solid and Solid doors and assumed the solid ones would be the best bet. Have PM'd you a plan to look at.
Got a wall guy coming to the house tonight so will see what he thinks will work best for that and hopefully he can let me know about 1 vs 2 doors. Id be happy with a single door on the rear side of the room but other half wants open plan so i figured double doors would be a good comprimise. Will defintely have a look into that rubber stuff you mentioned.
If money permits it will be a 7.1 system, got the fronts all sorted, just need to get the rears. Heard some good things about Selby Acoustics so will defintaely be contacting them when i need cables and the screen.
Thanks for the screen specs and projector recommendations, havent even started looking into screens and projectors just yet.

Well i decided to get the room walled off. The wall is up (steel frame with gyprock and sound insulation in), waiting on Bunnings for Double doors to come in then can finish it off.
Just wanted to check something in terms of screen size, for a wall 4m wide would you recommend a 120" or 150" screen or should someone look at getting a cinemascope screen instead, a bit confused about that one.
Also am trying to decide what projector to buy, any recommendation for under 3k that can project that size from around 2-5 Meters back?
Thanks in advance.
