Hi, I thought it was about time I shared my second creation with AVForums. I've wanted my own dedicated room for as long as I can remember and having recently moved into a 3 bedroom semi-detached I figured it was time I put my dream into action. The chosen room was the second largest bedroom and measures just over 11' square which was a reasonable size to work with. We would all love to have a bigger room but I can't complain as I at least about to get stuck into the my first venture in a proper dedicated cinema. I actually started buying new kit towards the end of last summer, i've bought 99% of the equipment second hand and saved a small fortune over the recommended rrp. The final kit list is as follows; JVC HD350 Projector Panamorph UH380 Anamorphic Lens DIY 110" Seymour AV centre stage XD screen ADA Cinema Rhapsody Mach ii Processor Behringer DSP1124p Parametric Sub EQ Lumagen VisionPro HD Video Scaler Dune Prime 3.0 BluRay (media) player 5 x Pro Audio Power Amplifiers Jamo D7 Left, Centre, Right (mounted behind screen) M&K S-85 rear surrounds M&K S550 side surrounds DIY 18" Fi audio SSD D2 Sub Sky HD Xbox 360 Demopad (iPad) remote. Global Cache IP2IR The decision to build a 2.40:1 screen complete with anamorphic lens was decided way before the room was started, nothing compares to the true cinematic feel the super wide screen gives... After all who wants to watch the news larger than the majority of major movies? Once I had all the kit sorted it was onto the build. I actually started the room at the beginning of December 2011, I had 3 weeks off over Christmas and my initial plan was to have the whole room done by new year. I now realise that the plan wasn't realistic as I eventually finished it last weekend (Easter weekend) it all went downhill once I hung the projector, I found myself watching my favourite scenes on repeat... Bad move! Anyway I learned some basic acoustic science and read quit a lot on room treatments for the home cinema environment. I eventually decided to fully sound treat the room with Wickes 50mm general purpose insulation slabs which as far as I can remember has a density of 60kg m/3. The entire front wall has been covered 3 layers deep (150mm in total) with bass traps bellow and above the screen. First reflection points have also been sorted floor to ceiling including clouds with a 50mm covering, the rear wall has a 100mm thick covering with a "faced" surface to reflect high frequencies to help liven the room (i didn't want it to sound too dull) the rest of the room has been treated up to ear height with more 50mm slabs. The effect is superb, upon entering the room the whole atmosphere changes and the overall sound is much more controlled without being too dull. The frames housing the acoustic treatments are covered in Maplins felt speaker cloth, the cloth is acoustically transparent so is ideal for this type of application. It's also great if you have a projector as it really does turn the room in to a bat cave . I had originally planned on using Devore but it was going to cost a fortune to cover the room, I may re cover the screen wall in devore at some point but for now it's perfect for me. The screen does hang in a black hole. The front LCR speakers are positioned behind the Seymour AV centre stage XD (acoustically transparent) screen and again offer that true cinema feel. The screen is 110" diagonal with a 2.40:1 aspect ratio. It also has a 40' radius to clear up the distortion "pincushion" that is caused by the anamorphic lens with a fairly low throw ratio. I was originally hoping to put the 36U 19" rack In the third bedroom but in the end it would have been quite a lot of work getting wires to and from the projector/speakers. I settled with the rack to the right hand side of the screen, I did have initial concerns over reflections but in reality this isn't an issue. All the lighting within the room is LED, the ceiling lights change colour slowly on a red, green, blue routine and the low level plinth lighting is a static 3000k white. Both are controlled independently using my iPad. I did quite a lot of reading on DIY subs and I'm glad I did, for the cost of a DIY it out performs an off the shelf item at a fraction of the cost. I settled on the Fi audio 18" dual 2 ohm driver as it was a very good price, it's driven by a Behringer EP2500 amplifier. These are my winISD and Google sketch up designs for the sub, I wanted a fairly easy design as its my first attempt at anything like this. The box is constructed from 25mm MDF. The box is a touch under 165 litres with a Qtc of 0.688, *I wanted more top end punch over lower end SPL. It sure does punch quite well . I also ran REW once the room was finished to see how well it performed.. As you can see it lacked some SPL below 20hz and had a huge peak at 45hz. I added some filters to the Behringer DSP1124p and here is the outcome. The sound is now much more controlled and balanced. It also has good low end output even when playing at reference levels. I may add a second in the future to make it a little more effortless but for now I couldn't be happier. Onto things I would do differently the second time round? Well I would ideally want the room to be a good 5 feet longer so I could move the seating position away from the rear wall a little and also hide the sub behind the screen wall. A black projector would also disappear a little better in the room... Maybe I should upgrade to an X30. Apart from that I'm happy and for my first venture in the dedicated room scene I'm extremely please with the rooms performance. I do however hope to get the JVC calibrated some time soon.
