An acoustic transparent screen allows loudspeakers to sit behind the image area. A standard fixed frame screen keeps the speakers outside the image and usually provides a simpler material approval path. Neither surface is automatically better. The right decision depends on the room layout, speaker architecture, viewing distance, projector geometry, image size and how much material testing the project can support.
Choose an acoustic transparent surface when the design requires a cinema-style speaker wall, a clean front elevation or a very wide image with left, center and right speakers aligned behind the screen. Choose a standard fixed frame surface when speakers can sit beside or below the image, the room needs a predictable wide viewing response, or the project values the simplest installation and replacement process.
The screen is one part of the front wall. Approve the screen, speakers, wall construction, projector and masking strategy as one system. MGF’s fixed frame projection screen range is a starting point for both directions; the exact surface and frame compatibility must be confirmed for the quoted model.
This guide is for AV integrators, distributors, contractors and project buyers who need a documented selection and project-planning path for this topic before requesting a quotation.
Woven surfaces allow sound through gaps between fibres; perforated surfaces use openings formed in the material. Neither construction name establishes the best choice for a room. The proposal needs an acceptable picture from the intended seats and an acceptable audio arrangement behind the screen.
Texture can become visible at closer seats, and a regular surface pattern can interact with the projected image as moiré. Audio needs a separate review because the surface may affect frequencies differently. These are reasons to compare identified candidates under the intended conditions, rather than assign a universal viewing distance or acoustic-loss number. Technical background: Stewart Filmscreen.
| Question | Review condition | Consequence |
|---|---|---|
| Is texture distracting? | Nearest intended seat and real content | Reconsider the candidate or seat arrangement |
| Is a pattern visible in projection? | Intended image size, optical geometry and surface | Investigate the pairing before approval |
| Does the speaker arrangement meet the brief? | Identified material, backing and audio layout | Audio designer reviews that assembly |
| Is the material offered for the screen? | Exact code and complete model | Exclude unapproved combinations |
Assume two candidates look acceptable from the rear seats, but one has distracting texture at the nearest row. That visual result can justify dropping it or reviewing seating. It does not decide the sound result. Similarly, a favourable audio evaluation does not approve image detail from every seat.
Avoid ranking all woven surfaces above all perforated surfaces, or the reverse. Keep the chosen material, screen structure and project conditions identifiable. A standard fixed-frame listing alone does not establish an acoustic configuration, and an unidentified demonstration swatch is not a confirmed supply item.

A standard fixed frame screen places the image surface on a rigid frame while speakers remain visible or are integrated into the wall outside the image. The design is often easier to coordinate with a conventional AV layout because the speaker path does not pass through the screen.
The key decision is not simply “standard versus premium.” It is whether the room benefits more from a predictable image surface or from the architectural freedom of a speaker wall. Review screen gain and viewing angle before selecting a material based on brightness alone.
| Decision point | Acoustic transparent | Standard fixed frame |
|---|---|---|
| Speaker location | Behind the image area | Beside, below or above the image |
| Front-wall appearance | Clean cinema-style elevation | Simpler conventional AV layout |
| Material approval | Requires visual and acoustic testing | Usually simpler visual comparison |
| Main image risks | Texture, moiré or light loss depending on material | Speaker placement may affect sightlines |
| Best fit | Home theater, screening room, premium media room | Training, conference, classroom and standard theater layouts |
| Installation focus | Speaker cavity, surface spacing and frame depth | Wall flatness, frame fixing and cable planning |
Give both teams the same room section. Show the viewing side, screen plane, proposed backing, speakers and surrounding wall construction in order. Use actual project dimensions and applicable product guidance; do not invent one speaker-to-screen spacing for every material.
VIEWING SIDE -> SCREEN PLANE -> PROPOSED BACKING
-> SPEAKER ARRANGEMENT -> WALL CONSTRUCTION
This is a layer map, not an installation layout. Exact positions and any backing depend on the reviewed assembly. A sample evaluated without those relationships may answer only part of the installed-system question.
| Changed item | Review to reopen | Reason |
|---|---|---|
| Material code | Picture and audio | Surface under approval changed |
| Backing added or changed | Picture, audio and installation | Layer arrangement differs |
| Speaker position | Audio and coordination | Earlier speaker relationship no longer reproduced |
| Seats moved closer | Texture and viewing task | Prior viewing observation may not apply |
| Frame or support | Assembly and applicable material approval | Swatch approval does not establish construction fit |
Assume the picture was reviewed without backing, then a dark backing layer is added to address the proposed rear wall. The earlier result does not close the changed assembly. Reopen the affected layer reviews, rather than declaring the material approved or restarting every unrelated part of the project.
The audio designer should select appropriate measurements or listening checks for the brief. Tie any result to material identity, backing, equipment, method and conditions. For the picture, use representative content at the intended geometry and include the closest and important side seats. Keep sample selection separate from acceptance of the completed installation.
Close the decision with the visual reviewer, audio reviewer and exact screen configuration linked. If they evaluated different sections or layers, reconcile that difference before treating their approvals as one system result.
For a standard fixed frame, send visible image size, aspect ratio, wall condition, frame border preference and projector position. For an acoustic transparent build, add speaker type, speaker depth, cavity dimensions, closest seat distance and whether the project uses front or rear projection. MGF can then confirm material availability, frame compatibility and the information required for a controlled quotation. See Factory & Production for production context and the Partner Program for distributor planning.
MGF can compare suitable product directions once the project brief confirms visible image size, aspect ratio, projector geometry, material direction, mounting condition, control requirements, quantity and destination market. The final quotation should identify the exact model, compatible material, drawing and approval information rather than treating a generic guide as a product specification.

It can introduce texture, moiré or some light loss depending on the surface and projector. Test the proposed material at the intended size and seating distance.
No. Confirm fabric dimensions, attachment method, tensioning and frame compatibility for the exact model.
Only when the speaker-behind-screen layout solves a real design requirement. If speakers can sit outside the image, a standard surface may be easier to approve and maintain.
Record the sample identifier, projector, image size, lighting, viewing distance, speaker layout when relevant and approval owner.
Send MGF the projector, required image, nearest seats and speaker-wall section, including the proposed backing. Identify the material candidates or the layer change being reviewed. The enquiry can then address documented material/frame combinations while the audio and picture decisions stay tied to the same assembly.
