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.

The Optimal Speaker Position is Right Behind the Screen

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 channel.

Material Orientation Eliminates the Moiré Effect

When dealing with weaved screen materials, moiré effect is a common issue that can ruin the image quality. Those strange patterns are caused by the screen material texture aligning with the grid pattern of the projector. To solve this, our signature AudioWeave material eliminates moiré by rotating the weave of the material out of alignment with the pixels. Combined with a finer pattern than the projected pixels, it completely eliminates the moiré effect.

Acoustically Transparent for a Truly Immersive Experience

After years of research we’ve engineered a material that allows a complete transparency of all audio frequencies passing through, exactly as they came out of the speakers. Your screen will not distort the sound quality while still delivering reference image projection. Complete audio transparency means that you can hide the speakers behind the screen and without any compromise in quality.

Amazing Audio Meets Perfect Pixel Accuracy with an AudioWeave Screen

Sound distortion will be the least of your worries with our acoustically transparent screen material. After years of research we’ve engineered a material that lets almost all audio frequencies pass through, exactly as they came out of the speakers. Your screen will heighten your sound quality while still delivering great pixel projection. Complete audio transparency means that your audience will enjoy a truly immersive experience, and your content will benefit from true high definition in both image and sound.

Choose AudioWeave for Superior Audio Transparency

The reason competing accousticly transparent screens don’t perform as well as Elunevision AudioWeave is because the perforations are way too large and much too few in number. With over 2000 holes/in2, AudioWeave has over 3x the holes per square inch than common mid-range weave materials and over 33% more holes per square inch than our nearest performance competitor. This graph shows that the Reference Studio AudioWeave 4K follows the original speaker frequency response very closely, with less than 0.35dB attenuation on average – an industry-best.

AudioWeave Delivers Unbeatable Audio Performance

The reason competing accousticly transparent screens don’t perform as well is the perforations are too large and too few in number. With holes size less than 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. This graph shows that the Reference Studio AudioWeave 4K follows the original speaker frequency response very closely, with less than 0.35dB attenuation on average – an industry-best.

As perforation size decreases and the density is increased, 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 similarly priced screens, and over 33% more holes per square inch than our nearest performance competitor, which is more than double the price. At the same time, each of our holes is 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 and video performance.

With unparalleled performance in both video and audio, make the Reference Studio Audioweave your best choice when it comes to total acoustic transparency. Because you shouldn’t compromise on image nor audio performance, spice up your movie nights with an exceptional screen material that delivers high-definition image and sound. The Audioweave was designed to make the most out of your home cinema for years to come.

Reference Studio AudioWeave Features


Reference Audio Performance

During the Research and Development phase of the screen, the key factors that make a good acoustically transparent screen were determined:

  1. Sound Transparency: the ideal screen should not alter the sound signal from the speakers in any way.
  2. 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.
The Solution:
  1. Produce the highest density of sound perforations to ensure lowest acoustical attenuation in the industry.
  2. Minimize the perforation size and total perforation surface area to reduce light leakage and increase image sharpness.
  3. Produce a fine weave pattern that is as smooth as possible.
  4. Introduce an angular shift to the weave pattern, so that the pixels of the projector do not align with the pattern, thus eliminating moiré.
  5. Minimize the thickness of the material without compromising material integrity or video integrity, thus giving maximum audio transparency.
  6. Absorb the minimal amount of light that does leak from the tiny perforations on screen with a sound transparent black backing

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.

The graph above shows that the AudioWeave 4K follows the original speaker frequency response very closely, with less than 0.35dB attenuation on average, an industry-best.


These results show that AudioWeave 4K material in combination with the specially designed black backing shows an average of less than 0.75dB overall attenuation. The attenuation is very linear, as the curves closely match each other. This performance, again, is an unmatched performance on a weave screen with a black backing.

To illustrate further, let’s see how the Reference Studio AudioWeave 4K’s performance compares to what is currently understood as the weave material performance leader (which can be purchased for anywhere from 2.5x to 3.5x the cost of our AudioWeave screen in the same size) as well as a typical “bargain” weave material (which can be purchased for anywhere between 0.8x to 1.5x the cost of our AudioWeave screen in the same size):

Remember, the dB Scale is not a linear scale, so a doubling in dB attenuation is a huge difference in relative % attenuation (for more information, see table below). This above results clearly shows that the AudioWeave 4K material has better performance than both the most expensive/highly rated materials available, which can cost as much as 3.5x the price as the Reference Studio AudioWeave 4K NanoEdge and still have frequency roll-off as we increase in the frequency spectrum, thus causing a great deal of harmonic distortion.

What this means is that simply increasing the dB output of the affected speaker will not get rid of the problem, because the competitors’ material is not simply attenuating the audio source, it is fundamentally changing it by attenuating different frequencies by vastly different amounts. The below table summarizes how the above dB attenuation transfers into linear attenuation. We can see below that the AudioWeave 4K material barely attenuates the whole range of audible frequencies (having a very small difference in attenuation between low frequencies and high frequencies), whereas even the most expensive alternatives do an extremely poor job of passing sound through them (having an over 30% difference in attenuation between the lower and higher frequencies).


This extreme attenuation of middle frequencies will be extremely noticeable, and loss of higher frequencies results in a loss of “airiness” and “sparkle” to the sound. The mid-frequency attenuation will affect the performance of virtually all audio coming out of your speaker, no matter the genre. The high-frequency attenuation will be very pronounced in high frequency instruments such as the violin, piccolo, clarinet, cymbals and piano. Furthermore, a variety of movie scenes (everything from a scene of a busy street in New York during rush-hour to a World War II movie action scene) will sound nothing like the makers of the movie intended. EluneVision Reference Studio AudioWeave 4K is the only material to keep its linearity all the way up to 20kHz (the highest audible frequency by humans) and have virtually no attenuation for a fraction of the price of the supposed high-performance competitors.

The fact that the performance of even the best $3000 – $5000 screens out there is not high enough and means you still have to perform expensive equalization is not acceptable to us, and it should not be acceptable to the consumer. EluneVision is thus changing what was conventionally thought of as a high-performing audio-transparent material – no longer will you have to perform expensive and time-consuming equalization on your speakers in order to get the most out of your audio setup.

The above graph shows that, in addition to having substantially better performance than its peers which cost numerous times more, our AudioWeave material is in a much higher performance class versus materials close to its price-point (0.8 to 1.5x of our screen prices). With the EluneVision Reference Studio AudioWeave 4K NanoEdge, there is no compromise.

The graph above shows the performance of the AudioWeave 4K vs the current performance leader’s weave with the use of each company’s respective black backings, which are used to black out any light that goes through the holes of the weaves. From the above graph, it is clearly evident that the AudioWeave material with its black backing follows the original signal very closely and very linearly, with a slight 0.35dB attenuation – meaning that there is virtually no harmonic distortion.  The current performance leader, on the other hand, suffers even more pronounced problems than it had without the black backing – overall attenuation is higher than the AudioWeave 4K material, not at all linear, and hence suffers from a great deal of harmonic distortion. Once again, the AudioWeave 4K shows that it will outperform any acoustic material, now matter the cost.

Finally, for reference, we include the audio performance comparison of the AudioWeave 4K versus a typical perforated, non-weave material.


We leave it as self evident that whether a competing material is a low-end perforated, a low-cost/low-end or a high-cost/high-end weave material, the EluneVision Reference Studio AudioWeave 4K material stands alone as the best-performing acoustically transparent material. Furthermore, screens featuring the AudioWeave 4K material have a price-performance ratio never before seen.

Testing Methodology: The original frequency response is a ProAC Response 1SC monitor with Classic 16.0 Tube Amplifier, using EL34 Ultralinear mode (Frequency response 8HZ-82Khz, 10W RMS) as the amplification stage. The microphone used is the Behringer ECM8000, which was calibrated prior to testing. Testing was done with 1/24 octave resolution and 20HZ speed tradeoff. The material is 12” from the speaker and 55” from the microphone, and placed in an anechoic chamber.

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 NanoEdge 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.

Speaker Setup

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 NanoEdge, your home theater setup can also easily be used to listen to 2.0 channel stereo music and CDs with flawless audio quality.


Maximum Resolution and Detail Reproduction with Minimum Light Leakage

The EluneVision Reference Studio AudioWeave 4K NanoEdge 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.

Moire Free With All Projection Technologies

Moiré is typically an issue with all acoustic weave screens. The Reference Studio 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 NanoEdge 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 NanoEdge screen 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 NanoEdge screen.

Perfect White Field Uniformity

Reference Studio AudioWeave 4K material provides perfect white field uniformity due to the material’s Lambertian diffuser nature. The brightness will be 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 color reproduction. To achieve this, the material is designed for a completely neutral color reproduction. The Lambertian diffuser property, in addition to a specially designed white base color, maintains color accuracy across the entire color 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 colors and will decrease the color 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 AudioWeave 4K screen material. 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 screen material 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.
