Vividstorm S Pro P vs Spectra Projection Phoenix Floor-Rising ALR
Compare Vividstorm S Pro P with Spectra Projection Phoenix motorized floor-rising UST ALR screens by gain, size, surface design and room priorities.
The headline difference is published gain—0.6 for the S Pro P versus 0.7 for the Phoenix configuration we reviewed. Do not treat that as a winner by itself: higher gain can trade against black-floor and ambient-light behavior depending on the optical surface.
| Feature | Vividstorm S Pro P | Competitor |
|---|---|---|
| Format | Motorized tensioned floor-rising UST ALR/CLR | Electric floor-rising UST ALR |
| Published gain | 0.6 | 0.7 Vantage UST surface on current Phoenix spec |
| Published viewing angle | 170° | Not stated in the current Phoenix product spec we reviewed |
| Published sizes | 72–120″ at linked merchant | Current Phoenix family includes multiple sizes; 72–120″ dimensions are published on 120″ page |
| Surface | UST ALR/CLR lenticular | Vantage UST 0.7 |
| Acoustic detail | 0.4 mm perforated lower black border | Do not assume acoustic transparency unless confirmed for the exact Phoenix configuration |
| Key tradeoff | Lower published gain, acoustic lower border, broad control set | Higher published gain on current Phoenix spec |
What actually decides this comparison?
Spectra’s Phoenix product pages identify the floor-rising model as electric with a Vantage UST 0.7 surface and 4K support. Published dimensional tables cover a range of common UST sizes.
1. Room geometry before brand preference
Measure the full case, not just the diagonal image. The case must fit the cabinet or floor location, and the UST projector still needs its own throw distance and height relationship to the image. A screen can be technically “the right size” and still fail the room if the case or projector footprint collides with furniture.
2. Light direction matters more than an ALR percentage alone
UST lenticular surfaces are directional. Published ambient-light percentages are not always measured the same way across brands, so they are poor cross-brand scores unless the test method is identical. Use them as manufacturer claims, then prioritize independent measurements where available.
3. Acoustic design is not binary
The S Pro P specifies a perforated lower black border. That is different from a fully acoustically transparent image surface. If your center channel or soundbar sits behind the bottom border, the feature may be useful; if your speakers sit elsewhere, it may not matter.
Which buyer profile fits each screen?
Vividstorm S Pro P profile
- You want a UST-specific rising screen with 0.6 gain.
- You value smaller size steps down to 72″.
- You can use the perforated lower border for speaker placement.
- You want app/voice/trigger controls described in the current Vividstorm spec.
Spectra Projection Phoenix Floor-Rising ALR profile
Prioritize the competitor when its exact size, surface characteristics, control system, case dimensions or current delivered price suit your room better. Compare the exact SKU rather than assuming brand-family specs carry across every variant.
Our decision rule
Start with room fit, then screen surface, then automation, then delivered price. If the S Pro P fits those first three constraints, it becomes the product to price-check.
