Reference Studio AudioWeave 4K Tab-Tensioned Motorized

Screen Features


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.

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.

This results shows 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.

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 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 Positioning

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.


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, 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.


Seamless Video Reproduction with Contrast Enhancing Sound Transparent Black Backing

The black backing is one of the most important aspects of an acoustic weave fixed frame screen. All acoustic weave screens will leak a bit of light due to the perforations in the screen. This light can then hit the surfaces behind the screen and bounce back into the material and thus lowering black levels.

To combat this problem, a specially designed, highly porous and low-density black backing is used to absorb the light leakage and provide better black levels. Not only does this enhance video performance, but as demonstrated above in the audio section, it will not negatively impact the audio performance of your home theater setup.


Reference 2D and 3D Performance

The Aurora 4K UHD series of screens 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 textures. 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

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.


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.


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.

The screens use a two-stage tensioning system. The first stage is composed of a frame tensioning system, where tensioning tabs are placed in between the material tabs to provide the flattest possible screen surface. The Reference Studio AudioWeave 4K series uses no fewer than 20 anchor points to fix the screen material to the frame.

The second stage uses force equalization rods, which are inserted into the perimeter tabs of the material to distribute the tension force evenly across all anchor points. The rods ensure that there is no sagging, creases or V waves in the material.

The Reference Studio 4K two-stage tensioning system means that the screen will be completely flat, and will remain so year after year.


Solid and Luxurious Construction

Professional All-Aluminum Housing

The Reference Studio AudioWeave 4K series screens have a sleek, black aluminum housing that is both durable and attractive. The matte black aluminum frame is made from aluminum and fire-resistant materials.

Support for in Ceiling Installation

The screen is specially designed with RF receiver built into the screen housing. This receiver allows the use of RF remote control and wireless trigger unit. This means that the screen can be hidden away for in-ceiling installations.

12V Wireless Trigger (Optional)

Numerous screens come with a standard 12V trigger port, but the problem with that is a 12V trigger wire will have to be connected from the screen to the projector. This is not only a hassle, but in many cases not a practical solution.

The wireless 12V trigger transmitter is the logical solution to eliminating the cable problem. Simply plug the Wireless stick into the trigger port of your projector, and the projector will now control the up and down operation of the screen. The Reference Studio AudioWeave 4K screen has a built in wireless receiver and will seamlessly integrate with any trigger-port ready projectors. This solution is elegant in that no wires are needed, saving both time and money.

Designed with Installation Versatility in Mind

EluneVision’s Reference Studio AudioWeave 4K Tab Tension screens are designed to be hung from the wall, fixed to the ceiling, using the brackets provided with the screen. Furthermore, all our screens come with remote control, wall panel control and 110V power plug for plug and play operation.

 Remote and Wall Control Offering Ease of Use
