A good home theatre is more than the sum of its parts. With a few small tips, the display, AV receiver and surround speaker set deliver an optimal result. The picture and sound of a home theatre system depend heavily on the individual conditions of the room. The factory settings of the devices usually already deliver a solid result, but still, leave room for optimization.

The positioning around the TV
As a rule of thumb, the distance to the screen should be three times the screen diagonal in order to be able to see the entire picture at a glance. The various presets in the TV presets, such as "Cinema", "Neutral" or "Movie" are usually already a good basis for a suitable picture, but you should then adjust it to your own preferences and spatial conditions in the detailed settings. Calibration DVDs or Blu-rays, which many professional publications offer for little money, are practical for this. The discs usually guide you step by step through the correct picture settings and include test pictures, videos and samples.
For the best surround experience, place all satellite speakers on an imaginary circle around the listening position, which is rarely achievable in reality. Modern AV receivers equalize the individual channels to compensate for distance and sound differences. You should not blindly rely on the programs, but correct them in the manual settings if necessary.
The right setting for the bass is just as important: The crossover frequency between surround speakers and subwoofer depends on the model and is described in the respective manual. A crossover frequency that is set too high or too low distorts the transition between bass and mids and thus quickly leads to either booming or thin voices.
What role does the size of the room play?
The positioning of the speakers and the subwoofer also affects the sound. Depending on the dimensions of the room, sound waves are reflected in the room and thereby exaggerated. By experimenting in different locations, you can quickly find the optimal position of the subwoofer.
Troubleshooting
If the home theatre doesn't sound good despite all the experiments and measurements, the room acoustics are often to blame: bare walls, tiled floors and glass surfaces reflect sound very strongly. Remedies include high-pile carpets, upholstered furniture or shelves that absorb or deflect sound.
