At Galaxy Home Theater, we understand that designing a custom home theater can be a daunting yet exciting experience. To help you make informed decisions, we’ve compiled some useful tips, resources, and insights into the essential components of a home theater system: projectors, screens, televisions, and surround sound audio technology.

Projection & UHD TV Screens

When mounting your projector, consider the throw distance and screen size. Ensure adequate distance from the screen to avoid any distortion.

Choosing the right screen to match your projector is crucial. Select a screen material that matches your room’s lighting conditions—either reflective for brighter rooms or a darker, matte finish for controlled lighting environments.

Audio

Dolby Atmos technology adds overhead sound, creating a more three-dimensional audio experience. Look for systems that support Atmos for a breathtaking soundstage. 5.1.4 and 7.1.4 setups: These configurations offer an excellent balance of traditional surround sound and overhead audio. Choose a receiver from brands like Yamaha or Marantz that supports these setups for optimal performance. Systems that are THX certified ensure that the audio quality meets strict standards. Consider using THX-certified speakers to enhance your movie nights.
