Where is the professionalism of home theater design reflected?

Nowadays, home theaters have gradually become a must-have entertainment space for wealthy families. In order to pursue a more extreme movie-watching experience and a more exquisite entertainment experience, many families are full of praise for home theaters. However, some families are turned off by this service after understanding the cost of home theater design. Why does the design cost account for a relatively large proportion of the official service quotations provided by Yingyinhui? Why? Why is the design aspect so important for building a home theater? Is its professionalism worth spending such a large price on?
The first point is that a home theater is different from an ordinary entertainment space. Its main function is to play movies. Why are we not willing to watch movies directly with movies but need to build a dedicated home theater? The fundamental reason is to restore the playback effect of a movie theater, so that the large screen stimulates our eyeballs and the surround sound shocks our ears. Therefore, when designing a home theater, the first thing designers consider is not the decoration style but whether the combination of various equipment can achieve the best working results. For laymen, even if we buy ultra-expensive equipment, we may not be able to achieve the best playback effect. Therefore, designers need to have good acoustic knowledge, which is something that everyone cannot do.
The second point is that after the equipment combination is completed, the designer must also decorate according to the actual space layout to achieve the best communication effect. For example: Try to avoid materials with more ripples in decoration materials to prevent problems in sound propagation. Therefore, the professionalism of home theater design is reflected in many places.
