Private Cinema: Build A Private Movie Theater

Owning your private cinema such as private cinema hire London for example is every movie buff’s dream for a unique experience. A project in which more and more enthusiasts and lovers of the seventh art are embarking to enjoy an incomparable experience with films, series, and video games. 

If the walls of your private cinema room are dark in color, you limit light pollution (reflections) and increase the contrast of the image, which is much more realistic.

The first rule is to create the darkest room possible to achieve a vibrant image with optimal contrast. The very localized lighting and the color of the floor and the walls must be studied to recall the atmosphere of professional cinemas. The installation of a false ceiling allows the embedding of Atmos speakers, LED spotlights, light strips, and a possible very trendy starry sky. The darkness requires guiding the steps of the spectators by placing luminous strips (LED) along the plinths, for example, which contributes to the “cinema” atmosphere of the room.

The following diagram illustrates some lines of thought for designing an ideal cinema room that favors the integration of loudspeakers and also lends itself to the use of conventional and wall-mounted loudspeakers, as in a professional cinema room. Building a wooden frame on a hard wall (stone, brick, breeze block, concrete, etc.) frees up space for thermal and sound insulation, cable routing, speaker recessing, and lighting. 

The concrete block walls are here covered with rock wool and receive a frame in cleats or rafters intended to install a stretched fabric covering. The wall facing the seats accommodates the sound-transparent projection screen and the built-in cinema speakers. Three front speakers supplemented by two side surround speakers and a subwoofer are the minimum required. 

In a large home cinema room, it is recommended to complete a 5.1 system with rear surround speakers to optimize the diffusion of ambient effects. Adding in-ceiling speakers and an additional subwoofer provides even more immersive sound.

A rafter frame is fixed to the concrete block wall to facilitate the integration of the projection screen and the enclosures on the front wall. The latter are isolated by rubber parts acting as silent blocks to avoid any risk of vibration. The projection screen is fixed on the wooden uprights. The three in-wall front speakers are placed on the same horizontal plane behind the screen, their faces flush with the wall. Care should be taken to center the central speaker about the screen perfectly. Also, we will place the left and right speakers near the left and right edges of the screen while ensuring that the canvas hides them.

A sound-transparent fabric allows the front speakers to be completely hidden behind the screen, making it possible to choose a large screen to promote immersion.

The partition receiving the screen must be moved forward about the existing wall to leave enough space to accommodate the speakers, the front face of which should ideally be parallel to the screen’s surface. The space left between the screen and the wall also allows the wiring of the speakers to pass through and can accommodate the air conditioning ducts.

On the side walls, vertical wooden claddings are used here to structure the space and diffract the sound. This piece is very absorbent, with a fabric stretched over the walls (few reflective surfaces), maximizing the performance of the loudspeakers. The floor is covered with a thick carpet placed on an insulating underlay to avoid downward sound reflections.

Once the lights are off and the movie starts, you can enjoy the show like in a real cinema

The video projector is positioned on the ceiling and ideally placed behind glass in a niche in the back wall. It is thus accessible from outside the room as in a real cinema. This makes it possible to limit the annoyance caused by the fan’s noise while offering the possibility of installing an additional air extraction system to evacuate the video projector’s heat.
