Brett_A Posted June 13, 2020 Share Posted June 13, 2020 (edited) Firstly, sorry for another advice thread but this may be a little different. I am turning a shed storage area underneath the second story of our house into a Theatre room 80%,/ man cave 20% Room dimensions are 8.8m*3.8m*2.7m. The walls - masonary block construction which are all below ground level, except one longer side (8.8m) which is the laundry and staircase on the other side The floor - concrete Ceiling - concrete suspended slab. Colour - low sheen black straight out of the taubmans black base. however right side wall has a graffiti mural starting from approx 3.2m (hence seating distance mentioned later) There are no windows within the room and the access door is via an external timber door, lined with carpet. This access is within a shed, so essentially a sealed room. My current system is paradigm monitor 11 fronts, monitor center 3 and Ultracube 12 sub. I am planning to add an SVS PB-4000 as the main sub and move the ultracube as the second/rear. The seating area will be located approx. 3m (this is approx where the mural begins so didnt want a speaker sitting over it) from the Length side of 8.8m and I am looking at using an Epson tw-9400 as the projector. The screen size I am considering is a 120" fixed frame screen. I plan to add a few big rugs and bass traps for reflections. My questions: Is this projector ok, or should I be looking at something more affordable like the tw-7100, given the size and no external lighting to compete? What surround and rear surround should I be looking at to compliment this system, with the idea that in the future I will be upgrading the fronts and center? Are the front and center currently big enough to compliment the room? Is the PB-4000 overkill to be used with the ultracube12? Any other suggestions more than welcome. I have never done this before, nor have I had a projector. Thanks in advance. Here is a dodge panorama photo of the room.

Same with the walls re clad with frame and insulation and plaster as a convention house does. can use this to also put channels in to run cables. floor can use good underlay and carpet will sort that out 18 minutes ago, Brett_A said: he seating area will be located approx. 3m from the Length side of 8.8m and I am looking at using an Epson tw-9400 as the projector. The screen size I am considering is a 120" fixed frame screen. 8.8m is a very long room, i wouldnt suggest use all of it for room given room is 8.8m*3.8m*2.7m. thats too long for how wide it is .... suspect that will drop to 3.5m wide by say 8.5m with a 120" screen that puts main seating at 3.65m. I would reduce overall room to 5.5 - 6m the rest you can either put in a false wall or use as a bar- study media storage room have all the gear etc in which will leave the actual room itself clean of all that and the gear should be aiming for 7.1.4 setup in something like this ! I wouldnt go less than the epson 9400. even consider with a complete light blocked out room and at clean slate stage if going something like a JVC as given blank canvas you can treat room and will be stunning for contrast and PQ qualities of the JVCs. dont have to go a latest one a previous gen one will do which should be able to pick up for about price of a new epson. 1 Link to comment Share on other sites More sharing options...
Brett_A Posted June 13, 2020 Author Share Posted June 13, 2020 So the main reason I cant put in a false ceiling is that all the services for the house are hanging from the ceiling (toilet, and shower) and would like to keep open to identify any leaks that begin from any tap washers/piping before they get bad an risk possibly destorying speakers and ceiling gyprock. I was planning on hanging some heavy curtains along the Left hand side 8.8m long wall and running good bass traps/dense foam on the right hand side 3m section before the mural. I was planning to place the projector at roughly 4.5m and only have one seating area also? Link to comment Share on other sites More sharing options...

I was planning on hanging some heavy curtains along the Left hand side 8.8m long wall and running good bass traps/dense foam on the right hand side 3m section before the mural. I would VERY much still do it. you are probably not aware but most houses upstairs down stairs have all this in the in-between ceiling space. if you do it carefully you could incorporate as a bulk head with access panels if need be - sections you can jsut remove for inspection service what ever (think of ceiling panels most commercial spaces have ..... with regards speakers in ceiling spaces you just use back boxes... many in ceilgin speakers come with those. takes care of protection with regards moisture dust etc. need to do something with that ceiling it is one huge expanse of concrete slab that will add to that bunker effect. same with the walls please dont just think adding some traps are going to fix it. think of what it is missing vs a conventional room with plaster frame and insulation tend to have... all this helps dissipate bass... rather than reflect that all that walls floor and ceiling will do as a bunker right now.

Brett_A Posted June 13, 2020 Author Share Posted June 13, 2020 The ceiling is now virtually impossible. If sheeted off with gyprock, the ceiling height would be a maximum of 2.2m because of how lov the services are and covering a substantial part of the wall feature. Is it possible to line completely with sound absorption foam? I’m prepared to make up huge frames filled with pink bats and spandex outer layer type material? do you think it would work with the left side done in gyprock and the right side left as block? I can roll out carpet on the floor, no problems. Link to comment Share on other sites More sharing options...

Sorry, I appreciate your feedback and take it on board I just spent a lot of money on the wall mural and am worried about the height only being 2.1/2.2m 1 Link to comment Share on other sites More sharing options...

There to dissipate rather than reflect which is what all concrete will do ps not sure seen the jvc x7500 listed. With a cage room like this I’d be getting a contrast monster like this and be much better than epsons not only in contrast but also in pure picture quality stakes Link to comment Share on other sites More sharing options...

I was just looking through images then and seen quite a few people running 2 bulkheads down each side about 1m in from the walls.. I might look in to this option. Im thinking the cable tray I was going to run overhead with downlights might rattle like hell from the PB-4000 too... I was just doing some reading on the JVC. Sounds like a good thing! 1 Link to comment Share on other sites More sharing options...

Being your room have all the license to be creative make what want it to be. Indeed bulk heads are very usefull things. Lighting, treatments, cables in ceiling speakers etc all easily incorporated ! the jvc very rarely come up. I’d grab it before gone Link to comment Share on other sites More sharing options...
