Detail 01
6 lb per cubic foot density
Dense enough to absorb well into the low-mids, not just tame hiss and sibilance like light foam does.

PrimacousticStratus Broadband Ceiling Cloud Gray
Independent shopping perspective
The Korena take
A 2-inch-thick, 24x48 broadband absorber in an aluminum frame, built to hang overhead. For treating first reflections off a ceiling in a mix room or live room.
Strong match
Who this is for
- Killing the ceiling reflection above a mix position
- Rooms where wall space is already used or unavailable
- Drum or vocal rooms with a hard, reflective ceiling
Consider the trade-offs
When to look elsewhere
- Renters who cannot anchor into ceiling joists
- Low-ceiling rooms where a hanging cloud costs headroom
- Anyone chasing deep bass control below the low-mids
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
2 inch thickness
Broadband down through the midrange. Thicker panels or corner traps still do the low-frequency work.
Detail 03
24 x 48 inch face
One panel covers a typical reflection zone above a desk. Two or three cover a full listening position.
Detail 04
Aluminum frame
Holds the panel flat and rigid when suspended, so it will not sag or bow over the years.
Detail 05
Semi-rigid inorganic glass fiber core
Holds its shape and does not crumble or off-gas the way soft foam degrades over time.
Detail 06
Acoustically transparent polyester facing
The fabric is there to look finished and contain the core; it does not reflect the high end back at you.
Final check
Know before you order
- 01Locate ceiling joists first. A framed 24x48 panel needs real anchors, not drywall.
- 02Measure the drop you want; hanging lower absorbs more but eats headroom.
- 03Plan panel count and placement before ordering. One cloud treats one reflection zone.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fix boomy bass in my room?
No. At 2 inches it works broadband down through the midrange. Low-end problems need thicker traps in the corners, used alongside this.
02How many do I need over my desk?
Start with one directly above the listening position, centered between you and the speakers. Add a second or third to widen coverage.
03Can I mount it flat to the ceiling instead of hanging it?
Yes, though a small air gap behind the panel improves absorption at lower frequencies. Hanging it slightly off the surface is worth the effort.
04Is the gray color the panel or the fabric?
The polyester fabric facing is gray. It wraps the glass fiber core inside the aluminum frame.
