Our theater room

Santy,

The laminate is 1.4 gain, BOC is about 1.1 to 1.2. Other than that, the picture quality is similar initially, but BOC is known to become bit pale/yellowish over time. But both are comparable.

Also, for bigger screens, BOC gets wavy as the material elongates due to its own weight. No issues there for laminate.

as for if its better than the laminates in India, I don't have much idea. But make sure the color is flat, little bit texture (not viewable for 2 ft) is okay. Matte White does the trick, you can go on bit grey side if needed.

If you don't have much info on these, then I suggest taking some samples of different laminates and compare those against BOC, side by side. That should help out with the decision.

Thanks Manoj. Already ordered for this lam 1209MF from Virgo

Its of matte white with a tinge of grey and totally flat without any texture. Hope this would suffice.

Nice. let us know how the picture looks when you get it.

Now, some screenshots from my handheld camera. They don't give much idea, but are fun to post and see.

Hi Manoj,

You system is good from where did you buy JBL Speakers for center, left, right and sourround speakers and which amplifier you are using to connect that speakers.

This is right screen window. The front 4 ft is covered in acoustic screen and then the next 8 ft is horizontal is also treated. I left the wall on top open because to match the left side which has a window.

I am planning to setup a home theater at my house and I wanted to know if this arrangement of adding acoustic dampening for just approx. 2 feet from the floor works in absorbing the base from the woofer, or is full wall dampening necessary for lowering the amount of base reaching the adjacent rooms??

thanks

Viral, Thanks.

All JBL speakers are bought locally, as used from other people. The surrounds were JBL 8330, liquidated from a movie theater. Since they had odd shaped, I ended up taking the drivers and cross over out, then built same volume cabinet for it.

I have updated my equipment/setup in last few months. I now use Sherwood R-972 receiver and Adcom GFA-7500 5 channel amp. Speakers are still 7.1.

Sound absorption for acoustic reasons and sound isolation are two different things. I think what you are looking for is the sound isolation. In this case, your aim is to not let the sound escape to outside and the focus remains on doors, windows and any structures to nearby rooms. I think you need to post this questions in the Room acoustics thread, there are people with better knowledge and first hand experience with it.

As I said above, my setup has changed quite a bit. I do not have any room treatments near the floor anymore. I had treatments there because speakers were on the ground. I have changed the screen to acoustic transparent. so the speakers are behind the screen, at room height. I have now treated my entire front wall and two front corners with bass traps. It's just based on how the speaker layout is.

Here are some of the pictures of our dedicated theater room. This was actually a family room, built by previous owner. We converted it into the dedicated theater room. Room is 13 ft wide x 20 ft long.
The screen is 2.37 aspect ratio, 12 ft wide, approx 58" height.

The speakers are put below the screen. Less than ideal, but these speakers have tweeters on top, and they are tilted up. If looked at the speakers from the seated position, the tweeter are pointed exactly at face. That's the compromise because I could not go for Acoustic Transparent screen. I built a frame and covered it with black speaker grill cloth. There is no grill on the speakers inside. So, only have the frame grill to cover it. This hides all the speakers, subwoofer and cables. Presents a clean view and also helps with immersion while viewing.

Below is the view on the left of the screen. You can see the red blackout cloth curtain covering the window. The front 4 ft from the screen and below the window are the acoustic treatments. Black color reduces the reflections on the screen.

Now, some info on the system. Projector is Infocus 777, used with Panamorph UH-380 anamorphic lens.

Speakers - 7.1 speakers
Left, center and right - JBL 4410a.
Surrounds - JBL 8330 x 4.
Subwoofers - Chase 18.1, sealed subs, 2 nos. Equalized by Behringer feedback destroyer.
receiver - Onkyo 605. (oh yes. )

Nice set up and I think you would enjoy the experience in this room.

Hi Manoj - Few quick questions. What are the dimensions of the screen and how far from the screen is the projector placed and at what height?

Sreejith,

Our theater and equipment went for a complete change. Now we have a 16:9 aspect ratio, 150" screen. Screen is 131" wide. We have two rows - Front row is at 11.5 ft from screen, second row is at 17.5 ft. Projector is mounted at 9 ft high, 17 ft from screen.

 

[mdharan]

Hello Manoj'
Congrats for your complete change in your HT...

Thankyou...

Thanks for the reply manoj. why i had asked these questions is because , i am also planning a similar setup(though not decided when ...i have few constraints on the room width (And hence the screen width) and the place to keep the projector. i am actually planning to just convert a living room to also work as a HT room setup.

the place where the projector will be kept is 18 ft away from the screen. This is fixed and cannot be changed. It will be placed 8.5 ft above ground. the width of the screen that can max be placed in 10"10' (This is the distance between the walls on the left and right of the screen)....so assume i use a max screen width of 10 ft....

1) My worry is ...will keeping the projector so far away, will the image go beyond the screen width (10ft) while projecting?
2) In your case, since u have placed the projector 17ft away, can u plz let me know whether u can adjust the projector settings to bring the image size to less than 10 ft wide in 16:9 format?
3) Which is the projector that u have used and what wud be its approx price in US?

Thanks,

Kurups, most home theater projectors have zoom capabilities which allow you to adjust the size of the image. Some more than others but I doubt any one of them is going to have too much difficulty projecting a 10 feet wide image from 18 feet.

But if you have a limited budget and go for the cheaper led projector (commonly known as data projectors), there's a good chance that you won't get any zoom option. For those you have to place them at a fixed distance to get a certain image size. Led PJs also won't be anywhere close to the HT PJs in terms of picture quality but still are good vfm due to lower initial cost and longer bulb life (upto 20000 hours compared to HT PJ's 3-4000 hours).

What's your budget for the PJ? If its 20-50k, you'll probably have to settle with a led PJ with no zoom and ceiling mount it somewhere in the middle of the room. If its closer to 100k, then you won't face any problems.

 

[abhilash220]

Nice setup Manoj!
I noticed that you have a Panamorph and changed the aspect to 16:9. Anything in particular that you did not like about 2.35?

i was actually thinking of something around 50-60k max. now it seems i will have to almost double it...anyway its a little long term plan...thanks for the detailed writeup.

Nice setup Manoj!

Abhilash,

2.35 setup was working fine. But the 16:9 aspect ratio was quite a small screen at 119", compared to 2.35 diagonal size of 152". Since there is lot of content including movies in 16:9, I felt its quite a small screen. So, decided to go with 16:9 (150" diagonal) and that also gives 2.35 at 142". Best of both worlds.

 

[abhilash220]

Thought so. I am using 2.35 126" inch screen and I agree that it's too small for 16:9. But its hard to give up that widescreen.
So right now your's is 142" from 11.5 feet. That must be some experience.

Which 150 screen did you get it?

Fixed or motorized?

Yes, it appears quite big. In 16:9, with added height, it simply is outstanding.
