The practical difference
The numerical gain difference is modest, so room fit and price should carry more weight than treating 0.5 versus 0.6 as a universal quality score. Spectra emphasizes its saw-tooth UST structure and strong overhead-light control.
Choose based on the room, not the logo
If you are choosing between two low-gain fixed-frame UST surfaces, pay close attention to overhead-light direction, black-level preference, projector brightness and whether the exact screen dimensions fit the wall. Strong light-rejection claims are directional, not magic.
Installation and ownership
Both are permanent installations. Confirm actual frame dimensions and mounting instructions for the exact size you buy; the comparison here does not assume the frames are dimensionally interchangeable.
What to verify before ordering
- Your projector is ultra-short-throw and the screen orientation matches tabletop or ceiling placement.
- The image area fits the wall with room for frame dimensions, cabinet depth and speaker placement.
- Your seating positions fit the screen’s viewing cone.
- Your problem light comes from a direction the screen material is designed to reject.
- The current merchant price, regional shipping and return terms are acceptable.
