In today’s post, we’ll answer the question: “How to design a home theater?” We’ll discuss the various elements to consider when undertaking such a project. Some aspects may seem obvious, while others might surprise you—both in terms of the number of available options and their unique features.
At the outset, it’s worth noting that all the information in this article applies to situations where we have full design freedom, without restrictions like room size and layout.
Room for Home Theater
To create a home theater, an appropriate room is essential. If you are planning a detached house, the task becomes a bit easier, as you can adapt the space to meet the theater’s requirements. In such cases, it’s advisable to avoid windows. The size of the room should match the number of seats and seating rows. Remember to leave space not only on the sides but also behind the last row—especially if you want to install rear speakers. (Later in the article, I’ll discuss aspects related to acoustics and speaker placement.)
If you are adapting an existing room for a home theater, you’ll need to control natural light, particularly if the room has windows. External blinds that provide complete blackout regardless of the time of day are the ideal solution. For visual consistency, Roman blinds in a shade close to the wall color work well.
Projector and Screen
The best choice here is a fixed frame screen paired with a laser projector with a native 4K resolution. Keep in mind that many parameters need to be considered when selecting a projector. One of them is screen brightness, which determines if the projector provides adequate luminance.
Choosing the right screen size is also crucial. Its properties affect image perception—the screen can reflect light differently, influencing brightness levels (this parameter is called the gain factor). While the idea of a large screen may be tempting, it’s not always the best choice. International standards define the optimal screen size based on the viewer's distance. For home settings, a 16:9 screen format is often recommended, as it matches the native format of most TVs and allows for the most content display without compromise. The 21:9 format, widely used in cinemas, is worth considering if you primarily watch movies and want the best visual effects in line with the creators’ vision, as many film scenes are shot in this format. However, choosing 21:9 comes with content availability limitations.
When planning a home theater, it’s also important to determine the main seating position, where the audiovisual experience will be most precise. A viewing angle of 45 degrees between the screen’s edges and this position is considered optimal.
Sound
Sound is another critical element. For a home theater, there are many possible configurations regarding the number of speakers. However, regardless of the number, their proper placement according to the chosen layout is key. In a home theater, we use surround sound, based on object-based audio technology. The most popular systems are Dolby Atmos and DTS:X.
I understand that it’s not always possible to place speakers as recommended, but it’s worth striving for as precise a setup as possible. To allow the speakers to generate effective surround sound, an appropriate sound processor is necessary, typically an amplifier selected based on the number and power of the speakers. In some cases, multiple amplifiers working together may be required.
Room Acoustics
Selecting high-quality speakers, such as those from Bowers & Wilkins, isn’t enough if the space isn’t properly acoustically prepared. Otherwise, even the most expensive speakers won’t reach their full potential (in fact, they’ll fall far short). There are many approaches to creating the right acoustic conditions. Detailed guidelines can be found in the “CEDIA – RP22 Immersive Audio Design – Recommended Practice” guide, though note that this is a 144-page manual requiring English proficiency.
Ventilation and Air Conditioning
When designing a home theater, we consider not only acoustic conditions but also a comfortable environmental setup. A home theater requires proper temperature and air quality control. Ventilation and air conditioning should be planned as a separate system, independent of the rest of the house, to minimize the sound transmission from the theater to other parts of the building.
Finishing Materials
The choice of finishing materials is relatively straightforward: the darker, the better, as dark colors reflect less light from the screen, enhancing the depth of audiovisual content. A dark decor may seem less visually appealing, but during screenings, most interior details become invisible anyway. Most importantly, the materials should be matte to prevent light reflections.
Home Theater Automation
Finally, it’s worth mentioning automation—still a relatively rare practice in Poland, as only a few companies possess the expertise, including ours. A home theater, like other rooms, can be automated. The key is ensuring that, during equipment selection, all devices are compatible within a single system. Popular home theater automation systems include Control4 and Crestron. Automation minimizes the number of remote controls and significantly simplifies daily use.
Is It Worth Building a Home Theater Yourself?
It depends. If you have the time, you can undertake the task. For someone unfamiliar with home theater design, it can take hundreds of hours. Even preparing the design alone takes considerable time, and without a plan, implementation is prone to many errors that can significantly affect the final result. For a technically inclined person, the project is certainly doable and can be very satisfying.
How Much Does a Commissioned Home Theater Cost?
This question is difficult to answer, as costs can vary greatly depending on the quality of materials and equipment. Selecting the equipment requires a discussion with the client to understand their needs and preferences. For example, a projector can cost anywhere from 20,000 PLN to 100,000 PLN. The same budget executed by different companies can result in vastly different outcomes. A good solution is a demonstration in a showcase theater, allowing the client to better understand the discussed aspects and choose the right system elements within their budget. Such a meeting can be arranged with us in Warsaw. If you’re interested, feel free to contact us.
