Detail 01
2" x 2" cross-section
Small triangular fill. It tames corner buildup and flutter, but does little below the low mids.

Independent shopping perspective
The Korena take
Thirty-six charcoal 2" x 2" x 24" corner pieces, sold as one pack. For someone filling the wall-to-wall corners of a small room in a single buy.
Strong match
Who this is for
- Filling every vertical corner in a bedroom or project studio
- Adding corner coverage after flat wall panels are already up
- Running floor-to-ceiling in a room with 8-foot walls
Consider the trade-offs
When to look elsewhere
- Serious low-end control — a 2" cross-section is small for bass
- Rooms where charcoal gray would clash with the decor
- Anyone needing to block sound from leaving the room

Charcoal
Dark gray only. It disappears against dark walls and stands out sharply against white.
Detail 05
About $3 per piece
Cheap per foot of corner, so overbuying by a few pieces costs little.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How many corners will 36 pieces cover?
Roughly 72 linear feet. At four pieces per 8-foot corner that is nine corners, which covers a typical room's verticals with spares left over.
02Does it come with adhesive?
No. Mounting is on you — adhesive, tabs, or a mechanical mount are all separate purchases.
03What color is it?
Charcoal gray, and that is the only finish in this pack.
04Will this soundproof my room?
No. This absorbs reflections and corner buildup inside the room. It does not stop sound passing through walls to a neighbor.
