Independent shopping perspective

The Korena take

A 2-inch semi-rigid fiberglass ceiling panel for treating first reflections overhead in a mix room, vocal booth, or conference space.

Product studyPrimacoustic Stratus Broadband Ceiling Cloud Black

Strong match

Who this is for

  • Killing the ceiling reflection between your speakers and mix position
  • Rooms where wall space is already used or unavailable
  • Adding broadband absorption without eating floor footprint

Consider the trade-offs

When to look elsewhere

  • Blocking sound between rooms — absorption is not isolation
  • Deep low-end control; 2 inches only goes so low
  • Renters who can't anchor into ceiling joists

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 01

6 lb per cubic foot density

Denser than common 3 lb panels, so it keeps absorbing further down into the low-mids instead of only taming highs.

Detail 02

2 inch thickness

Effective through the mids and upper bass. Below roughly 200Hz you'll still want thicker traps in the corners.

Detail 03

24 x 48 inch face

One panel covers the reflection point for a single listening position. Wider rooms or multiple seats need several.

Detail 04

Aluminum frame

Holds the panel flat when suspended horizontally. Fiberglass alone would sag and shed over a ceiling mount.

Detail 05

Acoustically transparent polyester facing

The fabric doesn't reflect highs back into the room, and it contains loose fibers so the panel isn't shedding overhead.

Detail 06

Inorganic glass fiber core

Won't feed mold or rot the way some foam and natural-fiber panels can in a humid basement studio.

Final check

Know before you order

  1. 01Find your ceiling reflection point with the mirror trick before deciding placement
  2. 02Suspension hardware has to hit joists — drywall anchors won't hold this overhead
  3. 03Confirm the mounting kit and panel count you're getting before ordering

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01How many do I need for a home studio?

One panel over the mix position handles the main ceiling bounce. Two side by side is common in rooms wider than about 12 feet, covering more of the reflection zone.

02Will this stop my neighbors hearing me?

No. Absorption panels reduce reflections inside the room. Stopping sound from leaving requires mass and structural isolation, which a hanging panel can't provide.

03Can I mount it flat to the ceiling instead of hanging it?

It'll still work, though suspending it a few inches below the surface leaves an air gap that improves low-frequency absorption.

04Is 2 inches enough for bass?

It handles low-mids well at this density, but true bass control below roughly 200Hz needs thicker corner traps. Treat this as reflection control, not bass trapping.
