**THX Tips: Optimizing Your Home Theater Setup**
[Home Theater Network HDAV.com.cn]
THX was originally created to ensure a high standard of performance in commercial theaters, but over time, it has expanded into home theater and private AV systems. Recently, AVS had the chance to speak with THX’s Chief Technology Officer (CTO), Scott Francis, about the key techniques used by THX to optimize display, speaker, and seating setups for the best possible audiovisual experience. Today, we’re sharing the full interview.
Scott Francis shared his insights on how to get the most out of your home theater system. He emphasized that while technology plays a big role, personal preference is equally important. “The best settings are those that provide the best experience for you and your family or guests. Don’t be afraid to make adjustments based on your taste. As long as the technical foundation is solid, you can enjoy your time.â€
One of the first topics discussed was the ideal placement for the monitor. “From the main viewing position, the center of the screen should be at eye level and directly in front of you,†he explained. “A slight horizontal or vertical angle of 10–30 degrees isn't too bad, especially with modern displays that have wide viewing angles.†However, he warned against placing the monitor too high, such as above a fireplace, which could cause uncomfortable neck strain. “If you usually watch from an angled position, that setup might work well for you.â€
When it came to speaker placement, Scott stressed the importance of symmetry. “Once your display is set, speakers should be placed symmetrically around the center. Most rooms aren’t perfectly symmetrical, so some adjustments may be necessary. If the left and right speakers are not equidistant from the center, it could affect the image and create strange sound effects.†He also mentioned that the center channel should be close to the display, either above or below the screen, to enhance immersion, especially for dialogue-heavy content.
For surround and height speakers, he advised ensuring they are positioned to deliver sound directly to the listening area. “Symmetry in the path length is crucial. I often see people place them randomly, which can lead to uneven sound distribution.†Regarding subwoofers, he noted that while bass is omnidirectional, their placement can still impact the overall sound. “Using two subwoofers can help reduce issues like standing waves. Experimenting with placement and delay settings can also improve the bass quality.â€
Regarding seating, Scott said, “Choose a spot where you can clearly see and hear everything.†He encouraged viewers to consider the room’s acoustics, including reflective and absorptive surfaces. “Avoid placing furniture in positions that block the sound path. Also, think about the angle of sound reflections and how they interact with your seating.â€
For sports viewing, he recommended using the “sports†preset on your display. “These settings are designed for fast motion and often include features like edge enhancement or motion prediction. However, not all monitors handle these features well. Some may produce a ‘soap opera effect,’ which can be distracting during live events.â€
As for sound settings, he suggested using modes like “stadium†for a more immersive experience, especially for sports like basketball. “A slight treble cut can make the audio smoother and more enjoyable.â€
