EluneVision Reference Studio AudioWeave 4K Fixed-Frame EV-F3AW-115-4kModel: EV-F3AW-115-4k
Through over a year of research and development of an acoustically transparent material, EluneVision has developed a material that meets our standards in minimal texturing, hole size and the highest perforation density in the industry. During the entire design process, two things were paramount: produce a material capable of both displaying the full detail of 1080p and 4K resolution video sources with minimal light loss and produce a screen that is completely transparent to sound.
The material is an extremely fine and yet acoustically transparent material that has over 2000 holes per square inch, which now sets the bar for the entire industry. Each sound perforation is only 0.0026" by 0.0035" in size.
The other engineering challenge was to deliver all the advantages of our Reference Studio 4K 100 material to the AudioWeave 4K. This meant designing a screening that has no texturing, no hot spotting and with perfect colour uniformity.
During the Research and Development phase of the screen, the key factors that make a good acoustically transparent screen were determined:
Sound Transparency: the ideal screen should not alter the sound signal from the speakers in any way.
Video Transparency: The ideal screen should match the performance of our Reference Studio 4K 100 material, which does not degrade the video source in any way.
Produce the highest density of sound perforations to ensure lowest acoustical attenuation in the industry.
Minimize the perforation size and total perforation surface area to reduce light leakage and increase image sharpness.
Produce a fine weave pattern that is as smooth as possible.
Introduce an angular shift to the weave pattern, so that the pixels of the projector do not align with the pattern, thus eliminating moiré.
Minimize the thickness of the material without compromising material integrity or video integrity, thus giving maximum audio transparency.
Absorb the minimal amount of light that does leak from the tiny perforations on screen with a sound transparent black backing.
Reference Audio Performance:
Unmatched Acoustic Transparency
Audio Transparency is the most important aspect of any Acoustic Weave screen. The ideal scenario is to have the screen material let all of the audio frequencies pass through it with zero attenuation. Of course, this is the engineering ideal, and cannot be achieved in actual practice. However, with careful design, a very small and inaudible linear attenuation with no comb filtering is possible. This is what the Reference Studio AudioWeave 4K material achieves.
Superior Audio Transparency Explained
The reasons for the inferior performance of the standard perforated material is that the perforations are too large and too few in number. With a holes size of 0.05” in diameter (1.27mm) and only 36 holes per square inch, physics simply dictates that frequencies above 1000Hz will begin to roll-off and certain frequencies will be cut off more than others, with a prevailing pattern of more attenuation as frequency increases.
As perforation size decreases and the hole density is increased, the audio transparency improves. This is where the EluneVision Reference Studio AudioWeave 4K material excels. With over 2000 holes/in2, our material has over 3x the holes per square inch than common mid-range weave materials which roughly match us in price, and over 33% more holes per square inch than our nearest performance competitor, which costs an astonishing 2.5x to 3.5x the price of our Reference Studio AudioWeave 4K screens. At the same time, each of our holes are about 85% smaller than common mid-range materials, and 25% smaller than the highest-end offerings, which allows our material to offer the best audio performance, while taking absolutely no performance hit in video performance.
The other reason is material thickness. The greater the mass of material in front the speaker, the greater the sound attenuation and distortion. Our material was engineered to be as thin, smooth and light as possible without compromising on video quality or material integrity.
The end result is that our material is truly audio-transparent, while other high-end offerings still require expensive and time-consuming equalization.
The most important speakers in a 5.1 or 7.1 audio setup are the front 3 speakers - the left, center and right channels. The center channel is the most important channel out of the three. Most of the dialogue in movies comes through the center channel; therefore it is imperative that the sound quality of the center channel is at its best. Typically, most center channels are located above or below the screen, which compromises their sound quality by lowering horizontal dispersion. The ideal scenario is to have the center channel directly in center of the screen flanked by the left and right channels.
Whether going with a 5.1 or a 7.1 speaker setup, the center channel's optimum position will always be in the center of the screen, at ear-level. Moreover, in a projection home theater, where the screen is typically much larger and wider than a traditional TV, the left and right speaker's optimal position are often behind the screen as well. This makes EluneVision Reference Studio AudioWeave 4K screens the ideal choice for any projection home theater.
Due to the transparency of the AudioWeave 4K material to sound, the only compensation required is to increase the SPL of the front speakers by 0.35dB (or 0.75dB if black backing is used) to compensate for the slight attenuation. The fact that this is the only compensation is important, as it is extremely simple for anyone to do. There will be no equalization required as the mid-range frequencies are not filtered out by the screen, and there no loss of the sound or “sparkle” on the high-end frequencies. Equalization poses a problem, as it is often time-consuming, and requires the use of expensive, trained professionals - this makes our AudioWeave 4K material the best, as it is the first material where absolutely no equalization is required. With the Reference Studio AudioWeave 4K, your home theater setup can also easily be used to listen to 2.0 channel stereo music and CDs with flawless audio quality.
Reference 4K Video Performance:
Maximum Resolution and Detail Reproduction with Minimum Light Leakage
The EluneVision Reference Studio AudioWeave 4K is engineered as very finely weaved material with holes that are only 0.0026 x 0.0035". This means only 1.8% of the surface area of the screen is actually composed of empty space. The finer and smoother weave pattern minimizes texturing and viewing distance, resulting in the capture of every detail from 1080P to 4K. Furthermore, the reduced light leakage means that more of the projectors light is returned to the viewer and not wasted, ensuring a crisp, bright image.
Above, we have a comparison of two images, with the same frame of the same movie being shown on the Reference Studio 4K 100 material and the Reference Studio AudioWeave 4K material from 8 feet away. This particular frame was chosen for a special reason: the whole image has the whole range of brightness, from the deepest of blacks, to the brightest of whites. These photographs illustrate very clearly that a premium was placed on making the Reference Studio AudioWeave 4K material not only the best material for audio-transparency, but also one that will not make the user have to choose between the best audio experience versus the best video experience. The Reference Studio AudioWeave 4K handles this any dynamic colour range with ease, without degrading resolution or image performance. The material is definitely a no compromise material from a video performance perspective.
Moiré Free With All Projection Technologies
Moiré is typically an issue with all acoustic weave screens. The Reference AudioWeave 4K material completely eliminates this issue. Moiré appears when the pattern of the weave matches the grid pattern of the projector. To resolve this issue, the material pattern is 15 degrees off the vertical so to completely remove moiré. Furthermore, the pattern of the AudioWeave 4K is so fine that it is often smaller than the projector pixel pattern, meaning yet another layer of protection against moiré.
The Reference Studio AudioWeave 4K material has been tested with LCD, DLP, D-ILA and SXRD projectors to ensure a moiré-free picture at various throw distances and viewing angles.
To the left is an example of how moiré can impact picture quality. When you zoom in, you see that the competitor's screen creates moiré on the woman's dress, causing artifacting patterns that are not supposed to be on the image. This is due to the fact that their weave material is not rotated by 15 degrees, so the pixel structure is too closely aligned with the material's weave. Furthermore, the moiré pattern also causes discoloration, as green hues are introduced on what is supposed to be a completely blue dress in the competitor's image.
Reference-Class 2D and 3D Performance
The Reference Studio AudioWeave 4K material is designed to maximize detail, resolution and uniformity for both 2D and 3D projection. To get the best 3D immersive experience, the screen must be free from artifacts, hot spots and as texture-less as possible. Any flaw in the material and in the reproduction will contribute to a loss of immersion and viewer fatigue due to increased cross talk.
Engineered for Active 3D and 2D with 1.15 Gain
With a gain of 1.15, one of the highest gains for acoustic weave materials; the Reference Studio AudioWeave 4K delivers high contrast images without any of the drawbacks of high gain screens such as hot spotting, texturing and graininess. The higher gain helps with brightness of the projected image and counters the loss of brightness due to active 3D shutter glasses.
Near-Perfect Lambertian Diffuser Viewing Surface
The thread used to weave the Reference Studio AudioWeave 4K material is chosen for its Near-Perfect Lambertian Diffusing properties. The end result is that you get a screen that is has a full 180 degree viewing angle and does not suffer from the effects of hot spotting, graininess, or texturing. The screen under proper usage conditions (viewing distance greater than 8 feet) will remain a near perfect canvas for the projector.
The surface of a material exhibits lambertian reflectance if the viewer sees the same image or brightness regardless of the viewer’s angle. From a more technical perspective, this means the incident light is scattered in all directions equally. A good example of this is an unfinished block of wood, where no matter what angle you view it, the luminance is roughly equal. In contrast, finished wood with a glossy coat of polyurethane exhibits specular highlights, which are areas of brighter luminance when viewing at different angles. While this glossy finish may be beneficial on furniture, it is the cause of numerous problems in projection screens.
Extremely Fine and Smooth Weave to Maximize Detail Clarity
At EluneVision, much effort was spent designing a projection material that is as smooth as possible. The Reference AudioWeave 4K uses a specially designed ultra smooth and fine weave that maximizes the picture sharpness while minimizing light leakage. This fine weave preserves the pixel structure, thereby giving the highest detail clarity, sharpness and definition of any projection screen released to date. This means, simply, that the geometry of each projected pixel remains as the projector manufacturer intended.
To illustrate this point, see the screen material texture comparison below, showing our Reference Studio AudioWeave 4K material beside the industry’s best materials.
From the above demonstration, it is clear that the EluneVision Reference Studio AudioWeave 4K material beats materials multiple times higher in price, and is far superior than materials even 50% higher in price.
Near Perfect Pixel Geometry
The extremely fine woven weave leaves pixel geometry perfectly intact. Why is this important? With 1080p projectors now standard and 4K projectors on the horizon, EluneVision’s material ensures that the effective resolution remains at 1080p, while other (more expensive) competitors degrade the pixel geometry to the point that the effective resolution is no longer even close to 1080p. Due to the fact that there is near-zero texturing and perfect preservation of detail clarity, the EluneVision Reference AudioWeave 4K material will perfectly resolve 4K resolution in both today’s high end and future 4K projectors, saving you a screen upgrade.
No Sparkles or Graininess - Complete Invisibility of Screen Material
Due to the use of a smooth and near perfect lambertian diffuser material, the screen has absolutely no sparkles. The screen was purposely engineered to disperse the light evenly in a hemispherical distribution, creating a perfect reproduction, as the director intended. The Reference Studio AudioWeave 4K material will easily pass any of the common sparkle tests, which include bright scenes in movies as well as sports such as hockey, football, etc. This means that viewer will always see the image displayed on the screen as the projector manufacturer intended, and will never see the annoying imperfections present on competitors’ screen materials.
Absolutely No Hot Spotting - 100% Screen Transparency
A big problem that you see with all but the best screens is an issue known as hot spotting. Hot spotting results in an area at the center of the screen with high glare and light, surrounded by a comparably darker image at the top, bottom and sides of the screen. As seen below, this results in a very unnatural image. This is not a phenomenon that only cheaper screens suffer from - there are countless examples of significantly more expensive Reference screens from competitors that suffer greatly from hot spotting, serving as a testament to EluneVision’s engineering efforts in perfecting the Reference Studio AudioWeave 4K.
Perfect White Field Uniformity
Reference Studio AudioWeave 4K material provides perfect white field uniformity due to the material’s lambertian diffuser nature. The brightness is even across the entire screen and there will not be areas of the screen which are brighter or dark to the viewer at any viewing angle. When projecting a pure white scene, the white level will be even from edge to edge, with absolutely no hot-spotting or texturing, demonstrating a reference level of performance and image quality.
Colour Neutrality and Accuracy
EluneVision’s new Reference Studio AudioWeave 4K material is designed specifically to achieve the highest level of colour reproduction. To achieve this, the material is designed for a completely neutral colour reproduction. The lambertian diffuser property, in addition to a specially designed white base colour, maintains colour accuracy across the entire colour gamut. Many other projection materials in the market today will exhibit a shift in hue, either to the blue, green or red. This creates an unnatural balance to the colours and will decrease the colour uniformity and vibrancy.
Above, we see a demonstration of this phenomenon. The top zoom-in shows the competitor's screen versus our EluneVision Reference Studio 4K screen. Note the color shifts that the competitor exhibits, as well as the minimization color shifts of the EluneVision Reference Studio AudioWeave 4K material. This results in the color accuracy of the whites and the reds you see in the EluneVision Reference Studio AudioWeave 4K image.
Ultra Wide Viewing Angle
Due to the near perfect lambertian diffuser properties of the Reference Studio AudioWeave 4K material, the viewing angle is a full 180 degrees, allowing seats to be placed off axis without any changes in brightness or white field uniformity. The image on the Reference Studio AudioWeave 4K material is consistent from edge-to-edge at all viewing angles.
To demonstrate this, photos were taken and posted below (the images were not re-touched). The first one shows a projected movie in a front view, while the second shows the movie at fairly extreme side view. Though the user would not normally sit this far off center, the photos below demonstrate the fact that in any way that you decide to arrange seating, the screen will perform with perfection from any view-point. This performance extends to the height and location that you decide to mount the projector. Whether ceiling mounted and centered to the screen, or table mounted to far to the left/right of the screen, the image the screen projects back to the viewer will not degrade.
Perfectly Flat Screen Surface
EluneVision Reference Studio AudioWeave 4K Screens use an easy to install snap on pre-calibrated anchor tensioning system. Each side of the frame has 5 to 20 anchors, providing a perfectly flat viewing surface.
Solid and Luxurious Construction
High Density Velour Pure Black Finish
During the engineering and design process of the Reference Studio AudioWeave 4K series screens, one of the goals was to improve upon the already excellent velvet frames of the Elara series. The specifications were to increase light absorption, as well as overall fit and finish. After researching different possible ways to accomplish these two objectives, an answer was found. By using a high-density velour material, the new velour achieved an increase of 40%+ in light absorption and managed to achieve a high end, plush and luxurious finish.
Installing the screen is a snap, literally. With our snap on tension system, your screen will be ready for primetime within 1-2 hours. Our screens also come with movable mounting brackets which allow greater versatility of where to place the mounting screws. With a few simple tools you’ll be watching all your favorite movies and sports in no time.
4. Our Commitment to Quality and Value
Long Term Durability
A screen is something you want to use for many, many years. It is key to purchase a quality screen so that it will outlast many generations of projector upgrades. The projector’s screen is like a painters canvas - a quality screen is needed to show the full performance of today’s and tomorrow’s projectors. The material itself is extremely strong and cannot be easily torn by hand. The screen material can be cleaned easily with mild soapy water and a sponge.
The performance of the Reference Studio AudioWeave 4K series screen material is equal or better than the best purposefully designed HD materials in terms of audio-transparency, sharpness, resolution, detail clarity, white field uniformity and viewing angle. The screen also does not suffer any of the drawbacks such as comb filtering, harmonic distortion, graininess, texturing and hot spotting that lesser-name screens suffer from. The Reference Studio 4K 5” frames single-handedly beats much more prestigious brands which only offer 1.5” to 3” frames, far too narrow for a screen of the EluneVision Reference Studio 4K caliber.
Five Year Warranty
The EluneVision Reference Studio AudioWeave 4K Fixed-Frame Screen is backed with a 5 year warranty against manufacturer defects.
The value of the Reference Studio AudioWeave 4K series is far superior to that of competitors. We offer better audio and video performance with much greater quality frames for about a third of our competitors prices. In terms of value and performance, the Reference Studio 4K line stands alone.
