EluneVision screens - Page 33

I actually answered in post 954...the projector you have is similar in the brightness department...in many cases, people find the need to turn it to Eco mode - not to save the lamp hours, but just because it's a very bright projector. You're going to have no problem with the brightness. A higher gain screen will just give you too unneeded brightness at the cost of hot-spotting, placement problems, seating flexibility problems.

Remember, you're not going to get much of a brightness increase with higher gain screens (but you'll get all of the negatives associated with higher gain screens) unless you place close to viewer eye level, and center it to the screen. This is a challenge for most people from a practicality standpoint in a dedicated HT room, as you can't just snug it up to the ceiling. In a multi-use living room environment, it's an even greater challenge, and an even bigger inconvenience.

Milosh, thanks I looked right past that post. I would have never even known about these screens without the forum. Once I get it, I'll post a thorough review. Already impressed with the customer service!

Update and initial review/impression

I ordered my 120" electric reference screen on the phone with Dave on Wen the 12th and it arrived on Monday the 17th and the shipping was very reasonable. I bought a remote trigger I can't use with my projector (acer H9500BD), guess I should have checked that first. The screen was very well boxed, with doubled boxing and plastic wrap, although most of the plastic had come off. There was a small 2" scratch on the front of the casing (didn't happen during shipping) but you can't really see it when it's mounted.

Mounting was easy enough and it comes with a long power cord so getting to power isn't a problem. There are 3 screen retention plates on the bottom for shipping that have to be removed before use. I almost missed the one in the middle. The motor makes some noise and I've seen guys posting about various screen motor-noise levels...I couldn't care less as long as it works. There are some waves/wrinkles in the bottom, just right of center that go up about a foot. I'm assuming these will flatten out on their own or I'll have to make an adjustment to the tensioning. I'm going to call before I touch anything. I didn't really notice it once the projector came on.

I was worried that since I'm using my living room with some ambient light and the screen has no gain, I might be wishing for a brighter screen. With the holidays, I've only used it twice. The screen drops down in front of my 63" plasma, which has an outstanding picture. In a word....wow. Beautiful colors, sharp clear picture. It looks amazing. We watched Total Recall last night. Great blacks, perfect contrast and I'm only using the preset cinema mode on the projector. Once it's dialed it, it's surely going to be awesome. We watched just 20 minutes of 3d and it's darker as expected, but I wouldn't say too dark either. But you really need to control ambient lighting for 3d. And the 3d is amazing. We'll be watching the Avengers in 3d tonight!

Edit. Dave shot me a note and asked me to simply give the corners a little pull while holding the bar with the other hand. Seems to have worked perfectly. Screen is as flat as glass.

Hi

I have sent you a PM to fix that small wrinkle, very easy, takes about 5 seconds to fix.

Thanks

It'll be nice if you can share the info here.

I'm looking for a screen to pair with the Epson 3020. I'm totally newbie and lost into projector world.

The projector is in the basement with complete lightning control. I would like to watch movies in dark but capable to watch TV with some ambient light too. Also, the 3D is very important and video games too. I'm looking for a fixed screen between 120" and 135". My throw distance will probably be 18' and seats 12-15'.

I looked at the Elera II Silver who seams great, but the Reference 4k too. But these two are not in the same price range... Will I really see a difference with the Reference 4k over the Elera II Silver with the Epson 3020?

The selling point to the Reference 4k is the texture free. Is it like tiny squares all over the screen? Could the Elera II Silver produces some texture?

Hello

Anyone here have Elunevision Reference Studio Tab-Tensioned Motorized 4K Screen who have a problem of waves even if the tension cable is adjusted?

Anthony

Does anyone recall the Black Friday/Cyber Monday promotion that Eastporters was having for a JVC projector + 4k screen? Specifically, I'm trying to remember what they adding as an incentive. Currently they're offering a ceiling mount, spare lamp, 2 free glasses and an emitter. Thanks.

Hi,

I am planning a theater room in my basement. I'm looking at one of the combos at Eastporter and wanted to confirm a few things.

Room size is 7.7' tall, 13.2' wide, and 33' long. I'd like to put a couch somewhere halfway down the room, say 15'-16' back from the 13.2" wall. Room is sufficiently dark, as the only two windows will be covered.

I will have B&W DM604 speakers on either side of the screen, so that gives me roughly 9' gap between the speakers.

Would I be correct in saying a 100" screen with a 105" tension bar length give me the best fit for the room? I'm considering the Reference Studio 4k Motorized.

Thanks,

With the description and sizing of your room, that sounds like the screen size you should be getting!

Thanks,

Milosh

Thanks Milosh!

One other question - where abouts in the ceiling should I have the electrician locate the electrical box for the plug-in? Left/right wall or the middle?

It would be on the right side.

Thanks,

Milosh

Hi,

Does anyone have compare the Reference 2.4 pure bright with the High Power ?

I already have a Reference 100 fixed frame but will like to buy a electric 2.35:1 screen to go on top of the 16x9

Just look at the Elunevision web site and there is no Pure Bright electric screen.

Hi Rick

We are starting to do very small batches of those screens, look for official release later this year. Let me know if that's something you need right away.

Thanks

I'm a new poster here, but I have been reading you guys for the last couple of days and I would like to thank you for providing so many answer to my questions, I just ordered an Elara II silver 106" screen from eastporter to match my not yet received Benq w1070.

I am not new to projector, I had 6 of them in the past, both high end and bargain priced but, god only know why, I purchased a 70 inch Sharp LCD last summer and got rid of my mitsubishi HC4000 and painted over my 100" diy goo-screen. All was good for a week or two but then I started hating the big LCD and I knew that this TV would not be in my living room for much longer, I tough LCD tv were better and more accurate than a projector but I was so wrong, can't stop looking at the bad clouding effect from the edge-lited LED and the over saturated colors.

So the TV was sold last week and here I am back to the projector world, after loosing 3 grand in this mistake. I notice that there is not that much video and picture about the installation of those screen, so I will document my install and post video soon for the would be buyers. All in all, the projector, the cables, bracket, screen and cable raceway cost me about 40% of the Sharp TV price, and I already know it will blow it away.

I need very soon... So I will send you a PM....

Unfortunately the shipping cost for the elunevision ended up to be too high for my remote town in Labrador west border. But I must say that eastporter were very helpful and offers me to cut their margin profit to subsidies the shipping fee a little. Their communication is top notch and I was refunded even if it was late at night. I will stop by their warehouse later this summer and will buy the screen directly. Until then I will be back to painted screen, I don't want to buy another screen elsewhere and they just prove to me that they are trustable and they care about the customer.

I was qouted under 2k for 160 pur bright 2.4.. that's $600 more thana Da-Lite HP 2.4 CineWhite...

Hi all! I come to the forum. I just bought a 4K screen elunevision Studio Reference 4k Tab-Tensioned Motorized 100EL - 1.0 Gain White Material 120".

Wanted to ask if this model comes with a white screen for the back area and if you see the image projected on the back. I ask because the other screens I have seen, have the back black and as usual is not the image that is projected on the back screen statements.





greetings and thanks

Hello,

I am possibly looking at a Elunevision Elara screen and looking for some advice as to which one I should consider. I have an epson 8345 ceiling mounted (7.5 ft) about 12 feet away. Seating is 13 ft away and is in a narrow room. Screen would either be 106 or 120. I have no ambient light and controlled pot lighting but ceiling is a white drop ceiling (8ft) and the walls are a light green colour.

Any input would be appreciated.

Thanks.

I would go with the EluneVision Elara II screen with your lighting and room conditions. From 13 feet away, I would personally stick with the 106" screen myself, but if you like your screens a bit bigger, you can go for the 120".

Thanks,

Milosh

best screen for an epson 5020UB ?
HT room is almost totally light controled.

For sure the Reference Studio 4K 100 is the way to go with the Epson 5020. Projector companies put a lot of money into making the projector colour-accurate, sharp, etc. The Reference Studio 4K will preserve the colour accuracy perfectly, have zero hot-spotting, no texturing, etc.

Has anyone had a chance to compare the Audioweave 4k material to the Seymour XD screen material?

Elune will send you a sample. I have samples of the Audioweave and XD. I havent done any formal testing (nor will I), just casual viewing with both samples stuck to my wall. (black backing under both)....along with two other weaves, an Enlightor 4k sample, and two micro perf samples. I have some more samples comming

IMHO, they are very close in functional look....XD *might* have a slight edge in gain. The Elune weave is just *slightly* less visible than the XD...but not enough to make a decision either way. Most say the XD weave is visible at 12' and less. I basicly agree with this. I'm sitting at 12' and I can still see the weave in both (XD and Audioweave) in bright white/lightish color sections. It's not distracting, but I can see it. For reference, I have 20/15 vision and I'm looking for the weave.

Nothing is even close to the tight weave of the Enlightor 4k.

EDIT** See my post below. I retested with each sample side by side, the Audioweave is less visible than XD allowing you to be 18" - 24" closer. XD has slightly higher gain **EDIT
Edited by Yzfbossman - 2/21/13 at 6:23am

Thanks for the feed back Yzfbossman, I have larger samples on the Audioweave, XD and Enlightor-4k materials coming in. I'm trying to figure out if its worth paying a premium for the Enlightor-4k or go with either the XD or Audioweave material.

Hi All

To clear up some things about the Weave Materials

I have the Seymour XD, and also tested the Enlighter 4K. The differences between the Seymour XD and Reference Studio 4K AudioWeave is basically that the Reference AudioWeave is a smoother material, so there is less texturing and less chance to see the texture, this also reduces moiré as well. The AudioWeave 4K material is more colour-accurate material on top of that. Generally, the people that come to the showroom can’t see the weave pattern until they hit closer than 7’. The person above has better than 20/20 vision, so while everyone’s mileage may vary, I can comfortably say that 95% of folks out there will not see the weave pattern from 9’ or 10’ away, just from dozens of viewings per month at the demo room.

More importantly, the sound transparency is very different between the materials. The Seymour AV's material has material attenuation starting 2kHz, there it is measured to be 1 – 1.5dB or so and getting as large as 3dB after 12kHz. It is this large differential in attenuation that is exactly what a screen is supposed to prevent, and our AudioWeave 4K does a much better job of it. A 3dB difference represents a 50% drop in power, so once you take this into consideration, these seemingly small dB differences actually make a huge difference. The Reference AudioWeave material has 0.5dB attenuation, essentially in the entire sound frequency range. If you put our screen in front of the speaker, you will not hear any difference versus the original sound source. The same is not true with their material. It’s going to be nearly impossible to judge this with a sample material, so realistically, don’t expect to get any audio information from the samples, only the video part can be properly compared from the samples.

The Enligther 4K, being a more extremely tightly woven material, will actually have worse sound performance than both Seymour and our materials. The holes are simply too small and it severely impedes the movement of air across the material. This results in large attenuation as we move to the higher frequencies of human hearing. We actually experimented with very tight weaves during our design and development stage. We decided against extremely tightly woven weaves as it conflicted with our No Compromise design principle. Our design goal was to create a material that did not compromise video performance over audio performance or vice versa. The holes were essentially microscopic and just simply too small for the air to move properly. This resulted in 4 db of attenuation. Furthermore, the linearity of the material is also not very good, as the response curve of the material does not follow the response curve of the speakers. This means you can’t simply just increase the volume to compensate, certain frequencies will be too loud and some too quiet. Also, remember, when you boost the volume you are also increasing the distortion of your audio system.

You can actually see the audio performance of the Enlightor 4K material in the image below, this is pulled from their own test results:



You can see from the curve that the difference varies from 0.5db to over about 5db as the frequencies increase. Average is about 3 db. Another thing you notice is that the material is that even for frequencies even less than 1kHz, there is 2db of attenuation, where as with our material, frequencies under 1kHz, there is essentially zero attenuation. This is because lower frequencies with longer wavelength pass through materials much easier. Also you notice the lack of linearity from the graph. You can see that at about 4-5kHz, the gap actually narrows and the difference becomes zero, this shows that the material is actually non-linear and causing certain frequencies to peak and others to get lower. You can see especially in the midrange frequencies, the difference between the red and blue lines changes quiet rapidly showing non-linearity.
With no perceivable difference in video quality and far degraded audio quality, we did not go in the direction of super tightly woven materials. Instead we designed our material to be tightly woven with a high density of very small holes for audio performance.

To get a better understanding of this, visit this link:

http://elunevision.com/audioweave-fixed-features.html

I know it is pretty, technical but it will give you a good understanding of just how the materials work.
So really, in conclusion, we designed a material that is the best balance in terms of audio and video performance. From realistic viewing distances of 7’ or more, you cannot see any difference between the perfectly smooth Reference Studio 100 4K material and the AudioWeave 4K.

If anyone has any questions, feel free to ask me.
Thanks

Thanks Dave for your detailed  post. I really appreciate you taking the time to be a part of the forums.

After reading your post, I decided to do a more dedicated side by side of Audioweave and the XD material. First I cut down the XD to the same size as my Audiowweave sample. I put them side by side with 6" of white heavy card stock between them.  (I don't have any sold screen samples to use) And I pulled down all other samples so we weren't distracted. Both were on top of black backing.

I called in my wife and 9 year old. I asked them to rate the three samples at 12' then 10' with no other instruction.  They both rated the same way from both distances.

1) Paper (with weave you have to give up something...they could tell)
2) Audioweave
3) XD

I then asked if they could see the weave. Neither could from 12'. And in this test nor could I. At 10' my wife & I could find it, my daughter could not.

So, my revised conclusion is that Audioweave will give you 18" - 24" closer viewing distance than XD.

Audioweave is now in the lead for my screen material over XD.

I'll update my post above.

Dave, quick question, what's the real world gain? It is clearly a bit less than the 1.0 gain XD

Thanks!
