Great forum, have been a long time lurker on here but now after some advice as we are starting to build. We are currently at the slab stage and looking further into our Theatre setup and Smart Wiring etc. Below I talk about the recess wall for this room but are unsure if we are along the right track with this, Framing starts next week and builder said we still have enough time to change this around if need to. Home: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ We are building the Cosgrove 261 As above and after advice for our Theatre Room. We are positioning the 105" Projector screen on the wall to left as soon as you walk in the room. The Recess Wall Dimensions Of Room 4670 * 4200 Viewing Area 4190 * 4200 (480mm Is that area as you walk in the door so guess we dont really want to count that) Height of Ceilings: 8'6 (2590) Depth Of the Recess: 180mm (This is as deep as builder said we could go) Originally when chatting with the builder he suggested a Recess Wall and we come up with measurements of 1440*2550mm and 700mm of the floor centered in the viewing area. I notice when most people talk about there rooms set back like this they talk about Bulkheads but im guessing where the door is situated that was not possible? Anyway to get the same effect I was talking to my partner yesterday and we were thinking something along the lines of the following. New Height: 2290 (Start the recess from the floor and recessing all the way up untill 30 cm from the roof, this leaves 700mm below where screen would start for cabinet and a spare 15cm above) New Width: 3250 (This leaves 40cm inside of the recess each side in case we have tall speakers etc we may want to put in there) Out side of the recess this leaves us 47cm on the right hand side of wall and 95cm on the left and centered of the viewing area) Any Advice? Re: Recess Wall For Theatre Room - Is this the right setup? 2Sep 14, 2010 12:08 pm My question is why do you want to do this? Is it just for appearance? Because floor standing speakers work alot better with space around them. By having them inside a recess either side of the screen you are limited to where they can be positioned and they will be very close to the side and rear walls in the recess. From an audio point of view this is the last thing you would do. It would be much better to leave as shown on the drawing and then the speakers have space around them and can be positioned anywhere you want. This is assuming I understand what the recess is for.

Hi Mozzie thanks for the reply. Yes I guess it is mainly for appearance most cinema rooms I have seen seems to have had it set out in between bulkheads which is the feel we are trying to achieve with the recess. Specialists Showrooms I have seen have had it this way and the speakers back there. Definitely keen to here more thoughts from you on this. Re: Recess Wall For Theatre Room - Is this the right setup? 4Sep 14, 2010 9:10 pm I see where you are coming from as I made the same mistake with my house, however my recess was 500mm which makes it even worse. From a positioning point of view there is a prefered layout for surround sound that based on how far you are from the screen dictates how far apart the speakers should be. Generally the further they are apart the bigger the sound stage feels. The other factor in determining speaker position is distance from the rear wall and side walls. From what I have read it is not ideal to have your speakers too close to the rear or side walls. Also they should never be placed equal distance from both the side and rear wall. Incorrect placement can make bass sound muddy or just contribute to a less than ideal sound. Just about everything I have read advises on not enclosing floor standing or bookshelf speakers and having them further out into the roof with minimal furniture around them allowing for better sound and ideal placement. I have noticed, as you mentioned, that you see countless installations and home theatres where people have done exactly that - located speakers in niches and cabinets. It depends of course on how serious you want your home theatre to be and how much money you are planning to spend. Alot of people are quite content to have a <$2000 budget for an unobtrusive surround system and if thats the case then you may prefer what looks best and apreciate the sound quality for what it is. I can tell you from experience that if you design a recess and decide you don't want it then you will be making a decision based on thousands of dollars of replastering, carpeting, woodwork VS a less than ideal home theatre design. Wall features are very popular in modern houses at the moment but one has to ask if they have any real purpose and if they place limitations on a rooms intended/future use. I'd also see if you can get Rod our home theatre install guru to comment on what his thoughts are. Re: Recess Wall For Theatre Room - Is this the right setup? 5Sep 15, 2010 10:49 am Thanks again for the reply. With your recess being 500mm deep do you think that made a big difference into the quality as our plans only have 180mm deep? Its just interesting and confusing as I see most Showrooms with these bulkhead look and most places have actually advised on the ground floor speakers at the front of the room that you advise not to do? In regards to the system we are looking to spend around $10,000 probably through someone like the Big Picture People but the main thing is just getting the right structures in place first (as I mentioned the framing starts next week) so if I want to make any changes to this recess it has to be done quick. Thanks heaps for your help so far I will PM Rod and see if I can get a reply from him aswell. Re: Recess Wall For Theatre Room - Is this the right setup? 6Sep 16, 2010 11:25 am It depends on if you want the recess just for the screen or an alcove for everything including the cabinet and front speakers. If you can only go 180mm deep then I don't see much point in a large alcove, however if you make a recess for just the screen then this is, even though not done very often (except by real HT enthusiasts), a positive thing to do. Otherwise known as a 'shadow box', if you recess the screen itself (with a minumum of margin around the screen, although you do need some to allow for mounting the screen) into the front wall then this reduces the potential for light from the immediate sides having an impact on the image on the screen. It does also add a little to the look of the setup as well. Floor standing front speakers is a hard option to beat sonically - they typically can handle more power and provide a fuller sound than their bookshelf or In-wall cousins, if that matters to you (how much this matters can differ from person to person - eg. others prefer the look and security of In-walls...). I'm putting a new floor in my kitchen, slate flagging on a standard concrete slab. I have allowed for a bed thickness of up to 20mm to accommodate the different… 0 17541 They using concrete or timber sleepers? Timber or steel uprights? Any drainage behind sleeper? 3 5883 |
