1.5x is a bit too far, feel like watching a big TV oni. I sit between 1.2 to 1.3 for that immersive cinema feeling. Have no problems with screen door. Thumbs up to the Epson TW700, actually no screen door from 0.8x. But if you are really sensitive to screen door then I recommend Panasonic projectors, even at 0.3x cannot see the pixel. But ultimately its ur choicelah....

Jason

Bro,

What about the unmotorised wall mounted screen with the same specs? How much does it cost?


Also,

Could you pm me your shop address n contact number as I will most probably drop by your shop one of these days..Could you do the HD65 projector demo at that time so that I can measure the size of the display for my home and check whether the screen size is suitable for me or not.

Thx

Hey Jason, I want to ask you about your speaker wires. I plan to get some as well for my home theater setup. Can you tell me where you bought it from and how much you paid for it? I have people quoting me RM 8 - 9 per meter for some cheap a$$ monster and belden cable.

I bought it from US thru an online retailer. I posted the information here. Don't forget to add in shipping charges is u take this route.

When choosing the cable, look at the size of the conductor and not the insulation jacket. My final advise is not to go too thick, arbout 14-16AWG should do nicely. I used 12AWG and almost regretted is during installation coz theyr are just so hard to work with!!! Accoustic Research sells 14 and 16AWG cables at quite reasonable prices.

Btw, Belden are good cables, you can buy an entire reel from a wholesaler rather than getting a shop to sell by the meter. For the other cheap a$$ monster cable (I assume u are not referring to the US based Monster Cable Company), I would give that a miss unless u can get it real cheap.

Hope this was helpful.

I reckon 1.2-1.3 is too near and you need more eye movement, 1.5x-1.6x will be good for 720p and 1.8x -2.1x for wga

Your reasoning to sit at a given distance due to eye movement and projector resolution seems to be flawed.

Assuming the screen size is the same, whether you have a 720p, 1080p or WGA projector, the amount of "eye movement" is the same for a fixed seating distance. So for a 100" screen, if you sit 130" from the screen, your eye movement is the same for any projector resolution. When determining the seating distance, there are a 2 things to consider:

1. Keep a viewing cone of about 30degrees. More or less up to you, as long as you are comfortable. For me, I sit at about 1.3x screen width which works out to be a 40degree viewing cone.

2. If screen door bothers you, ie u don't like to see the pixels, then you will have to sit further back until you can't see it. The lower the resolution the further back u need to sit, ie 1080p can sit nearer, 480p may need to sit further back. This has nothing to do with eye movement.

So even if you decide that 1.3x is the best seating distance in terms of viewing cone, but because of screen door, you may need to sit at least 1.5x.

Hope this clears it up.

Bro, the cost of normal screens depend whether it is a fixed screen or wall screen (roll).

wow....i wish i stayed at ur home!! haha...

Jasonlky,
First of all, congratulations for a project excellently executed!! It's absolutely marvelous.

I have a few questions though..

1) Your wall panels; what kind of material do you use? acoustically treated? fiberglass wools? How thick is it?
2) I'm thinking of using either curtains, wood panels or some other padded materials to cover the walls. Any advice?
3) Your floor; solid wood? wall-to-wall carpet?
4) The cabinet to house your electronics; build-in cabinets or purposely made hi-fi racks? materials?
5) Can I give you a visit? I need some ideas to do mine.


Thanks

Sounded wierd the first time I read..... scarylah


Thank you for the compliment.

1) Wall Panels are made of 2inch foam glued to a ply wood backing. Then covered with fabric. All normal off the shelf stuff used, no special accoustically treated stuff.
2) What are you trying to achieve with the curtain/padded material? If you are trying to reduce reflection, then heavy curtains would do or something similar to mine would do just fine.
3) Floor is solid teak.
4) Normal MDF boards used for the cabinets, nothing special. This cabs are used to houe the Home theatre systems only. My audiophile stuff will be placed on the floor and special patforms just in front of screen near the ESL speakers.
5) I live in Bukit Rimau shah Alam. Drop me a PM if you are in my neighbourhood and I'll try to accomodate you.

Jason

Thanks Jason,

I don't quite like curtains.. would probably go for your approach.
Will definitely drop you a PM soon

Sure thing, look forward to it. I have been showing off the AV Room and my DIY projects every weekend since Begining of the year. Hope it will slow down a bit.

Jason

good point about bringing up the viewing cone, I notice the discussion trend especially in AVS is that the wider is better, obviously that means, moving to 1080p at sitting nearer distances to the screen... i.e. using more elite equipment...

Added on February 4, 2008, 1:52 pmyeah panny ones with smoothscreen have no SDE (screendooreffect) but at 720 (my AE900) if sit like 1x screen distance (diagonal)... you will start to notice the pixel structure instead of the main movie images...

Wide is better in most cases, coz fills your field of view and thus gives you a very immersive experience. However you want to avoid sitting too near when watching movies like "The Blair Witch Project" and "Cloverfield"... . Halfway thru the show I could not take it, vomited and then slept immediately!!

Jason

those are "shaky hand home video camera" technique mah... different style of artistic camera work..

I cldnt take it too. Too dizzy to watch

You've been very kind to entertain the visitors. I've not even made an appointment to see your setup.

In order not to inconvenience you too much, perhaps you should nominate a date so that those interested can show up. This way you can demo to several people at once (and also avoid repeating answering the same questions individually). Also helps you to know when people are coming (rather than surprise call on a weekend).

Cheers and Gong Xi Fa Cai to you!

I am not so sure about organising such a day... I am happy to accomodate any visitors if I am free.

Jason

jason,

your wall panel. As u mentioned its a plywood then covered with fabric. Is it DIY? No acoustical treatments/certified right?

where u get it? price?

how does it perform? better insulation/absorptions?

me looking for a some kind of studio foam for my HT room. But quite hard to find lah.

My wall panels are made of ply wood backing with 2 inch foam covered with fabric.

I am sure that you have your reasons for needing studio foam. I have been in a recording studio before and it is not a condusive environment for listening to music, recording yes, but not listening. Music tend to sound dead and unappealing.

Before any renovation, my room was accoustically ok. Even with the new glass cabinets, I find no untoward sound reflections or vibrations. The panels are made by the contractor that built the entire room for me, no acoustical treatments.

As I mentioned my room was accoustically fine before the renovation, with the wall panels, some of the high frequency reflection/prominence has been reduced. Mids and lows remain unchanged.

I have no way to compare my wall panels to commercially available insulation/absorption materials. So I cannot tell how it performs. If you are having trouble finding studio foam, try Ebay.

Jason
