FS: 120" 16x9 Stewart Studiotek 100 screen material
Been using one in the store for about a month, very impressed with it TBH.
its very balanced in color once calibrated, it is bright for a DLP at this price but remains in control with the correct balance of color, black and white is amazing also.
processing speed is fantastic at this price point - definitely our number 1 DLP under 10k
anyone in the sydney area who wants to arrange a demo feel free to PM me
Thanks for the reply... I agree with you! I am looking for any sort of actual experience with the Crystal Cube. You are one of the only people online who has any subjective experience with it so far and I would love to hear your thoughts. Would you recommend it over the JVC DLA X500R? I saw a Crystal Cube this week but thought the contrast was a little weak with the blacks not being real black. Once you calibrated it do you think it would out perform the JVC? I plan on using it with a 130" 16:9 Stewart screen vs the JVC with a 130" 2.35:1 Black Diamond...
Thanks in advance,
im gathering you are not using the 2.35:1 on cube becasue of the custom lens mounting solutions or is there another reason ?
personally either way i am not a JVC fan, reliabilty for me has been an issue for us, also i think if you are going to go DILA you may as well visit the Sony range 55ES and above depending on your spend there SXRD is same tech as DILA but i personally feel these are better value for the money and reliability has been 98% for nearly 12 months of sales.
I think I'm going back to demo the Crystal Cube this weekend. The only down side it I've never seen the JVC in action so it's hard to tell...
firstly you cannot get a true 2.35:1 image without a lens - lens memory may work to keep the aspect ratio ok but it does so with zoom affect this is by far accurate in terms of reproduction, and more importantly the projector is using a certain amount of its processing actually shooting the black bars ! if you use an actual lens then there is no zoom affect and all of the projectors energy is dedicated to the actual presentation.
If you are using a dedicated theater i would choose DLP over any other type of projector as they produce the best blacks and whites in a dark room environment, some may disagree but there are reasons why only the best projectors in the world are DLP and not LCD this opinion comes from 8 years experience looking at projectors every day of the week.
If you are not in a dedicated room or you are using the projector as a media projector for many different purposes with low ambient light etc than LCD can work quite while as contrast may help you out here although it usually means a loss in accurate color gammit
you can use a crystal with a 2.35:1 lens we usally make a custom lens mount thats all.
as far as screens go thats a whole different story and i would really need to speak to you at length about your setup further, if you would like to call me and have a chat i would be happy to advise you further.
good luck with it all
As for the Cube, the specs just don't look good. I mean Sim2 is good, but at the price of the Cube, things just don't add up. They rate it at 2500 Lumens, but at that price that's just not going to end well, that's the sort of specage you get with a BenQ W6000, or W7000. Sim2 makes some great stuff, but their "inexpensive" ones just aren't known for being anything special, rather the contrary, quite mediocre for the price.
Like I said, if you want a DLP, look at something like the Runco LS5, Q750i, or a DPI Cine 1000, etc. The LS5 is really still the top of the heap of the sub $10k DLPs. But frankly, unless you've got a specific reason not to go with a JVC (like lag for gaming) I find it hard to recommend anything else for HT these days, they are an incredible value, and among the brightest HT projectors available once calibrated (don't believe the 2500 Lumen BS from HT projectors under $20k, it just doesn't happen unless you don't care if the picture is remotely accurate).
This is really helpful stuff but with the lens memory is there distortion due to zoom effect and isn't the back bars still being processed using a anamorphic lens?
As for the Crystal CUBE, I've seen it in action and it is quite watchable...good brightness and detail...decent contrast, though blacks are not as black as they are on LCOS/DILA. Rather than compensating for the brightness deficiencies of the JVC by using a Black Diamond, I'd consider compensating for the slight black-level deficiency of the CUBE by using a unity gain grey screen. The BD screens are known to suffer from color shift and other irritating artifacts. They're fine for ambient light situations, boardrooms, etc., but not the best choice for a home theater.
I still consider myself an advocate for DLP, but I just have a hard time believing this machine will put out PQ anywhere close to a JVC. Judging from it's throw ratio this is using the smaller .65" DMD which means it's going to take a hit on native contrast and it makes it harder to achieve the same kind of image sharpness normally seen with the larger .95" DMD. The MSRP of $4995 means they didn't go head over heels with the lens and is another reason this probably isn't going to give us that "wow" regarding sharpness we normally get with a 95" DMD + decent optics. I would make a wager the Runco LS-1 $3999 MSRP is going to have a sharper image with better contrast (native and dynamic) due in part because it has an amazing lens for the price and it uses a .95" DMD. So unless you NEED the brightness the Cube offers there's no reason to look at this particular model. There are far better options in terms of overall PQ in this price range in my opinion.

technically it's 'perfect' reproduction of the source using that method. it's the only way you get a 1:1 pixel image. if the projector has good blacks, and is bright enough, zooming to give a '2.35:1' image is totally fine. using a lens upscales the image SLIGHTLY, but then again, the jvc eshift upscales the image to 'uhd'...
black diamond screens are used more for rooms with high ambient light, not for projectors with low brightness. for low brightness, in a light controlled room, you'd want a high gain screen. but I don't think the jvc qualifies are low brightness unless you're wanting an insanely bright image, or shooting 140"+
DLP still seems to have the best ansi contrast, but LCOS definitely has better blacks and on/off contrast. personally, I find the ansi contrast on my x35 to be great, and the on/off contrast is what really steals the show. when the scene gets dark, the image and entire room get scary dark. fades to black are impressive, especially if it's from a bright scene. basically, if the weak point of LCOS is it's contrast with mixed scenes, then it's got no weak points. the jvc though, does have issues with motion resolution. long medium paced screen pans are death on this projector
I would not recommend the black diamond unless you intend to do a lot of lights on viewing
Thanks for the help. I think you're right, no black diamond. I'm set on Stewart studiotek 130 G3 or ultramatte 150 at 130" diagonal in 2.35:1. I know you said 1.0 gain but the studiotek 130 seems to be the reference standard. Do you think the JVC x500R is bright enough for a screen that size?
Thanks in advance!

i have an x35, which i think is the same lumen output? anyway, I've got it showing on a 120" diagonal 1.0 gain screen with the iris fully closed and find the picture very pleasing to watch. i'm quite positive that I would be happy with the brightness, but it's hard to know what others think is acceptable. i'm the kind of guy that turns the backlight down to 20%-30% on an LED because it's painfully bright from the factory...
I own a StudioTek 130 G3, and I would recommend that over a Black Diamond screen. Can you paint the room pastel greys / browns / anything but white? And hang a few decorative dark drapes !
Give me a call or an email for a screen quote. If Stewart won't send you samples, we at AV Science can send them to you, just FYI.
