In March 2026, we completed a project of oversized acoustic projection screen customization for a high-end commercial theater. As the core equipment in high-end audio-visual scenarios, Acoustic Projection Screens, especially the high-end commercial theater acoustic projection screen, have far higher requirements for sound transmission effect and picture flatness than ordinary scenarios. Customized oversized models even test the all-dimensional capabilities of design and production. The client needed an oversized screen of 20 meters in width and 8 meters in height this time, which not only had to be compatible with 8K projection, but also ensure no sound field attenuation, and the on-site installation had to be completed within 3 days, becoming the core demand of this customization.

This high-end commercial theater is located in the core business district of South China. Previously, its audio-visual upgrade plan was shelved many times due to technical difficulties of oversized screens. The supporting capacity of conventional screen frames is insufficient, and sagging and deformation are prone to occur under oversized dimensions. Moreover, the perforation design of ordinary acoustic projection screens will lead to excessive attenuation of medium and high frequency sounds. This is also a common problem encountered by most high-end theaters in Acoustic Projection Screens customization. The following are the core requirements and corresponding difficulties of this project, which are also typical pain points in customizing oversized acoustic projection screens:

In response to these problems, our technical team formulated an exclusive solution around three core directions: acoustic projection screen frame structure design, acoustic projection screen material selection and modular assembly. The key design points are as follows:

1. In terms of frame design, we use aviation-grade magnesium-aluminum alloy to make customized keels, add four transverse reinforcing ribs, and adopt a triangular mechanical structure for bottom support at the same time. Each keel has passed the latest static load test in 2026, and its load-bearing capacity is 60% higher than that of conventional frames, eliminating the sagging and deformation of Acoustic Projection Screens from the structure.
2. In terms of material selection, we match an 8K micro-hole acoustic projection screen and accurately control the perforation rate at 2.9%. Detected by the acoustic projection screen audio attenuation test, the attenuation value of sound after passing through the screen is stably within 2.8dB, which is fully in line with the sound field design standard of the theater. At the same time, the diffuse reflection coating of the screen can improve the color reproduction of 8K projection.
3. In terms of assembly engineering, we adopt the concept of modular design acoustic projection screen, split the entire screen and frame into 8 independent modules, complete the whole process of pre-assembly and debugging in the factory, and make precise laser splicing marks for each module. Only splicing and flatness calibration are needed on site.

Actually, factory pre-assembly is the key to the efficient implementation of this project. We completed the screen stretching, frame splicing and preliminary test of sound transmission effect in the workshop, and solved all possible problems in advance. The 3-day installation period estimated by the client was finally completed by us in 2 days. After on-site debugging, both the picture flatness and sound transmission effect of the screen far exceeded the client’s expectations.

After this customization service, many clients consulting about oversized acoustic projection screen customization have asked several core questions. We have sorted them out for the reference of more partners with audio-visual customization needs:

Q1: How to avoid deformation of oversized Acoustic Projection Screens after long-term use?

In fact, the core lies in the mechanical structure design and material selection of the frame. Aviation-grade magnesium-aluminum alloy has stronger rigidity. Combined with triangular support and transverse reinforcing ribs, it can offset the tensile force caused by the self-weight of the screen. Our customized frame will also undergo anti-aging tests to ensure no obvious deformation for more than 5 years.

Q2: What core indicators are referred to when conducting the acoustic projection screen audio attenuation test?

We mainly look at the attenuation value of medium and high frequency sounds. The standard for high-end commercial theaters is generally within 3dB. At the same time, we also need to detect the penetration uniformity of sound to avoid uneven sound volume in different areas of the screen. This is also the reason why micro-hole acoustic projection screens are more suitable for high-end theaters than ordinary ones.

Q3: Will the modular design acoustic projection screen affect the overall flatness of the screen?

No. Our modular splitting is designed according to the stress points of the screen, and the splicing joints of each module adopt laser positioning technology. The gap error after on-site splicing can be controlled within 0.1mm, which will not affect the overall effect of the projection picture at all, and can also greatly reduce the difficulty of transportation and installation.

From receiving the demand to the final implementation in March 2026, our Acoustic Projection Screens customization service has always been based on the actual scenarios of customers. From demand communication and scheme design, to factory production and pre-assembly, and then to on-site installation and debugging, each link is followed up by professional engineers throughout the process. In fact, the screen customization of high-end commercial theaters is never a simple size enlargement, but a dual precise adaptation of picture and sound.

If your commercial theater or large audio-visual venue also has the demand for oversized acoustic projection screen customization, or has special sound field and picture requirements for the high-end commercial theater acoustic projection screen, you can let our technical team make an exclusive feasibility assessment for you, so that the Acoustic Projection Screens can truly match the ultimate audio-visual needs of the scenario.
