Best Acoustic Transparent Projector Screens Canada 2026 — Woven Screen Guide
Acoustic transparent (AT) projector screens allow sound from speakers placed directly behind the screen to pass through without meaningful loss of audio fidelity or image quality. For home theatre enthusiasts in Canada, placing the left, centre, and right speakers behind the screen is widely considered the gold standard — sound originates from exactly where the on-screen action occurs, creating a completely immersive cinematic experience that no speaker-beside-the-screen setup can replicate.
Why Speaker-Behind-Screen Is Superior for Home Theatre
In a commercial cinema, every speaker is behind a perforated screen. This is not an accident — when dialogue, effects, and music originate from behind the image rather than from speakers sitting beside or below the frame, the brain processes the audio as part of the visual scene rather than as a separate element. The result is dramatically higher immersion, reduced listening fatigue, and a more natural soundstage for movie content. With an acoustic transparent screen, you can replicate this experience exactly at home, even with large-format screens up to 150 inches and above.
How Acoustic Transparent Screens Work
Sound transparency in a projector screen is achieved by one of two methods: a woven fabric structure or micro-perforations. In both cases, the physical gaps in the screen material allow sound pressure waves to pass through while the projector's optical image is formed on the front surface.
The key engineering challenge is balancing transparency for sound with opacity for image. A screen with very large holes or a very open weave will transmit sound extremely well but will also show diffraction patterns — visible rainbow-like artefacts — when displaying a bright image. A tight weave or very small perforations are better for image quality but may reduce high-frequency sound transmission at very long distances.
Modern woven AT screens have advanced to the point where, at normal viewing distances of 10 feet or more, the weave pattern is invisible to the naked eye, and high-frequency roll-off from the screen is negligible for the vast majority of home theatre audio systems.
Woven AT Screens vs. Micro-Perforated AT Screens
Woven Acoustic Transparent Screens
Woven AT screens are constructed from interlaced optical fibres or threads that create a continuous fabric with microscopic gaps between each thread. The weave is engineered to be optically uniform — no single gap is large enough to create a visible hole pattern at viewing distance — while collectively providing a significant open-area ratio for sound transmission.
Benefits of woven AT screens:
- Virtually invisible weave pattern at viewing distance — no hot-spot or diffraction artefacts
- Even, smooth image surface without discrete hole visibility
- Excellent broadband sound transmission including high frequencies
- Easier to clean than micro-perforated screens (no holes to trap dust)
- Higher tensile strength — less prone to sagging on large-format frames
Micro-Perforated (Micro-Perf) AT Screens
Micro-perforated screens use a solid screen material — typically a PVC or polyester base — with thousands of tiny discrete holes punched or laser-drilled through the surface. The holes are small enough to be invisible at normal viewing distance but allow sound to pass through the gaps.
Benefits of micro-perforated AT screens:
- Can be manufactured in a wider variety of surface materials (including some ALR or grey-base materials)
- High peak white gain possible on a per-hole basis
- Easier to inspect for damage than woven fabric
Limitations: micro-perf holes can occasionally be visible at close distances (under 8 feet) on bright scenes, especially with 4K content where the eye resolves fine detail. The holes can also accumulate dust over time, requiring more careful cleaning.
Gain and Material Considerations for AT Screens
Acoustic transparent screens are almost universally available in matte white with a gain of approximately 1.0 to 1.1. This is for a fundamental reason: the open structure required for sound transparency is not compatible with the directional optical coatings used in ALR or high-gain screens. The micro-gaps that allow sound through would disrupt the angular-reflective surface needed for ambient-light rejection.
This means AT screens perform best in dedicated home theatre rooms where ambient light can be controlled — ideally a room with blackout curtains or a basement media room. In a bright living room, an AT screen will not deliver the ambient-light rejection performance of an ALR screen.
For gain, the sweet spot for AT screens is 1.0 (unity gain). Screens with gain above 1.2 on a woven structure are uncommon, and high-gain variants tend to introduce narrower viewing angles that compete with the wide seating layouts common in home theatre rooms. A good 4K projector with 2,000–3,500 lumens paired with a 1.0-gain AT screen in a light-controlled room will produce a beautiful, cinema-quality image.

Installation Requirements for AT Screens
Proper AT screen installation requires planning both the screen and the speaker placement together:
- Gap between screen and speakers: A minimum of 12–18 inches between the screen surface and the face of the front speakers is recommended. This gap prevents the speaker cabinet from appearing as a shadow through the screen and allows adequate sound dispersion behind the screen before it reaches the viewing area.
- Speaker positioning: The tweeter of each front speaker should ideally be at or very near the vertical centre of the screen, and the left/right speakers should be positioned at screen-edge or slightly wider. The centre channel speaker is typically mounted at screen centre height on a dedicated stand or shelf.
- Screen frame depth: Fixed-frame AT screens require a frame deep enough to mount the screen at least 3–4 inches proud of the wall, allowing the cable and speaker stands to fit behind. TrueThrow's fixed-frame screens include deep-profile frame options suitable for AT installations.
- Room acoustics: A room with AT screen speakers benefits from acoustic treatment on the wall behind the screen (absorptive panels) to manage early reflections from the rear wall that could blur the soundstage.
AT Screen Comparison Table
| Feature | Woven Acoustic Transparent (TT-WAT) | Micro-Perforated AT |
|---|---|---|
| Sound transparency | Excellent (broadband) | Good to excellent (depends on hole density) |
| Image sharpness | Excellent — no visible weave at distance | Very good — micro-holes invisible at 8 ft+ |
| Visible hole pattern | None at viewing distance | Can be visible under 8 ft on bright scenes |
| Cleaning | Easy — microfibre wipe | More care needed — holes trap dust |
| Price (CAD) | $$$ | $$–$$$ |
How to Choose an AT Screen
Room Type
AT screens are designed for dedicated home theatres, media rooms, and light-controlled spaces. If your room has significant uncontrolled ambient light, consider whether a standard ALR screen with speakers beside the screen frame would better suit your environment. For rooms where you can draw blackout curtains or where ambient light is minimal, an AT screen with speakers behind it is the definitive choice.
Speaker Size and Depth
Measure your front speakers before selecting a screen. Tower speakers (floor-standing) require a screen frame at least 6–8 inches in front of the wall to allow them to stand freely. Bookshelf speakers on stands are more flexible. Ensure your speaker depth (front-to-back) plus the minimum 12-inch air gap fits within your room's available screen-to-wall depth.
Projector Requirements
With a matte-white AT screen (gain ~1.0), ensure your projector is rated for the screen size at your room's ambient light level. For a 120-inch AT screen in a dark room, a 2,000-lumen 4K projector is sufficient. For a 150-inch screen, 3,000–4,000 lumens is recommended. The AT screen itself does not add gain, so projector brightness is more important here than with ALR screens.
Budget
Woven AT screens at the TrueThrow TT-WAT level represent the highest-quality home theatre screen technology. If budget is a constraint, a smaller size (84″–100″) woven AT screen paired with quality bookshelf speakers behind it will outperform a large perforated screen with lower-end construction. Quality of execution matters more than screen size for a true home-cinema experience.

Frequently Asked Questions
How much does an AT screen affect sound quality?
A quality woven AT screen introduces a loss of less than 1–2 dB in the high frequencies (above 8 kHz) at normal home theatre listening levels. This is inaudible in most home theatre contexts and easily corrected with a minor EQ adjustment on your AV receiver or processor. The immersive benefit of speakers behind the screen far outweighs any marginal high-frequency roll-off.
Can I use an AT screen with a Dolby Atmos or DTS:X system?
Yes. An acoustic transparent screen is fully compatible with any home theatre audio format including Dolby Atmos, DTS:X, and Auro-3D. The AT screen applies only to the front L/C/R speakers placed behind the screen. Height and surround speakers are positioned conventionally in the room and are not affected by the screen.
Will the speakers show through the screen?
At a minimum 12–18 inch gap between speaker and screen surface, and with the screen properly tensioned in a deep-profile frame, speakers will not be visible through the screen during projection. Dark-coloured speaker cabinets (black or dark grey) behind a lit screen image are invisible to viewers.
Do I need a special projector for an AT screen?
No. Any standard long-throw or short-throw projector works with an AT screen. The matte-white surface is compatible with all projector types and technologies including DLP, LCD, and laser. UST projectors are not recommended with standard AT screens because the steep throw angle and non-directional matte surface will cause hot-spotting — for laser TV with AT, a specialised UST woven screen is required.
What sizes does the TrueThrow AT screen come in?
The TrueThrow TT-WAT Woven Acoustic Transparent Screen is available in 84″, 92″, 100″, 110″, 120″, 135″, and 150″ diagonal sizes in 16:9 format. Custom sizes may be available — contact TrueThrow for enquiries. View available sizes →
