  1. Acoustic treatment.

    Sounds (yes pun intended) like a good solution. How much is this stuff and where do you buy it?
  2. Acoustic treatment.

    Hey bro can you send me a pick of your treatment. Is that ok.? HERE is a link to my blog where I documented my room build.
  3. Acoustic treatment.

    Hey thanks cavx for your response. Appreciate it. When i clap my hands there is no reverb. I think this is due to the big mattress and other stuff in my room. So you think just start with some side and front wall stuff. When you say front wall that always indicates the wall at which you view everything? Do you think the foam stuff from Clark's rubber is fine? Not no reverb, maybe just not hearing anything offensive. If the room has reflective walls, it is going to have some reflection. Whether it bothers you or not is another thing. I never really understood what I was supposed to hear or not hear until I added foam and other sound absorbing panels to walls. Then, when I couldn't hear certain things, I suddenly realized how much I was ignoring the issues in the room. Yeah front wall is screen or LCR wall.
  4. Acoustic treatment.

    How does the room sound when you do a loud single hand clap? Is there much reverb? I'd start with some front and side wall treatments first to reduce reflections and add thicker material as you go. Bass traps are designed to "trap the bass" so that it does not reflect uncontrolled around the room. When that happens, you get inphase and out of phase collisions and this creates the peaks and dips. Adding traps really requires in room measurements. Typically bass traps are big and made from dense materials like fibreglass (the stuff you stick in the walls.) Be careful, I have heard a room that over did it and in the end, they had a suck out in the range most rooms peak (40Hz~70Hz). When I added foam to my corners, I had measured 10dB peaks at 35Hz! Adding foam plus moving the subs a bit and I was able to pull that down to just 4dB. EQ is really the next step for me. I am looking at a mini DSP (EQ and crossover) and 6CH Rotel amp for my LCRs.
  5. Enabling "anamorphic" on JVCX9500

    Great. So can we move on to the problem at hand? How does the owner of the JVC turn on his anamorphic mode?
  6. Enabling "anamorphic" on JVCX9500

    They continue to play a valuable role to this day. Content creators either have gone back to film + A-Lens or used one with a digital camera (to allow them to use all of the imaging chip) for new films. There is a certain look to the image that is favorable. Directors like James Cameron claim not to like them due to a short depth of field, hence why he went with Super35 for his Scope films. In the home projection arena, it is simple maths - 100% Vs 75% of the panel for CinemaScope. I choose 100%. As far as MTF goes, I think plastic projection lenses have done more damage than an all glass, fully corrected anamorphic does. This thread is also asking how to activate how to turn on the anamorphic mode on a JVC. Just because a certain user feels that there is no need to use them doesn't make their existence redundant nor gives him the right to crap all over them or anyone that uses one.

    Not allowing it to scale 2160/60P is as dumb as those older 1080P projectors that could not scale 3D.
  8. Enabling "anamorphic" on JVCX9500

    I'm still in the dark ages 1920 x 1080 here for a while yet.
  9. Enabling "anamorphic" on JVCX9500

    As mentioned, more pixels on screen as you can use the full panel and not throw away 25% of the vertical rez. For 1920 x 1080, that is a difference of about 1/2M pixels. Move to UHD and we are talking about over 2M pixels wasted on black bars! That is more than the whole of 1920 x 1080! Pixels are expanded by 33% in both directions when you zoom. Using a n A-Lens only expands the pixels horizontally. There is also about 14% (measured and documented) light increase over the same sized zoomed image when using an A-Lens. With UHD and HDR-10, you need as much light on screen as you can get. The ONLY thing that makes zooming more appealing is price.
  10. Enabling "anamorphic" on JVCX9500

    Interesting. And here i thought Netflix was a bit backwards with all the program I watched being 1080/60P (and back to 3:2 pulldown) when I streamed this through my OPPO 203D. On my BenQ, both anamorphic modes, VS and HS, worked fine with any refresh rate, so I am puzzled as to why the JVC will only work at 24fps. It may not be a bug, but is seeming to be a bad design. it is about remapping the image and it should not matter that the frame rate is.
  11. A combination of foam cylinders, moving the subs and fixing the crossover on the plate amp made a massive difference. No, not perfectly flat, but better than I had. Having heard a system where the measured (at the seating position) response was flat across from 30Hz, 40Hz, 50Hz and 60Hz with a slight drop at 70Hz and 80Hz was VERY desirable. What I find undressable now is the typical 60Hz "room boom" that most people think sounds awesome. I have a single bed foam mattress that needs a new home and I am curious to see what impact this has on my room if I store it behind my screen. Out of site and if it helps tame that last of those peaks, then a win win.
  12. Help me setup a theatre room

    Thanks, and even after 7 years, I still like it. It is still my chill out place and I actually like listening to music in there. I think the treatments (and they don't need to be expensive, mine were a few hundred) really make the room what it is. After EQ, I got a pretty flat response. Next upgrade is probably going to be ATMOS. If I could change anything, it would be size by making it bigger.
  13. JVC autocal

    As long as you can go in and manually tweak the white balance with a meter taking reading off the screen, I think this would be fine. Each screen manufacture will claim their screen reflects the equal amounts of RGB, but the truth is, the fact that UHP lamps themselves bias the colour of the white light towards green means some external teaking won't go unnoticed. Remember, there is no grey quite like D6500K (x = 0.313, y = 0.329).
  14. Help me setup a theatre room

    You are supposed to roll a base coat and go back and texture. I found that just slapping on a nice thick coat with a 4" wide brush gives the best result. There is a black base pigment added that tends to come out this way. If you do as the instructions suggest, you don't get the black showing through. HERE is my room build.
  15. Help me setup a theatre room

    I used Suede Effects "Pompee Ash" (spelling?), a nice dark grey, for two reasons - 1. I can't paint to save myself, so the rougher the effect the better it looks 2. It is matt finish, but because it is textured, it does not mark like normal matt paints. My first dedicated room was matt black and I would NEVER go there again. Once it was marked, you could not clean it without making it worse.
