Stereo and Home Theater Systems questions, answered by experts

The cost is influenced by the brand and quality of components, the room size and shape, and installation complexity. Custom systems and advanced professional calibrations are typically more expensive but can provide better sound quality.

For movies, television, and games that feature surround sound output, no other setup than true 5.1 or 7.1 surround is capable of matching the fidelity and presence they offer. If, however, music is your audio priority—or you tend to favor older movies and broadcast television that’s unlikely to include surround sound output—you might be better off putting your money toward two high-quality speakers designed to reproduce stereo sound.

Installation typically takes 1-2 days, depending on wiring and equipment setup.

For optimal sound distribution, position the front speakers equidistant from the TV, the center speaker below or above the screen, and the rear/satellite speakers behind or to the side of the listener. The subwoofer can be placed anywhere but may sound best in corner areas.

Costs depend on speaker type, labor, home layout, and whether custom wiring or mounts are required.
