Auralex 2 in. Cornerfills (Grey, Pack of 36)

CornerFills are sections of flat-cut Studiofoam corner acoustic absorbers that are beneficial in 2 ways.

Aesthetically, they give you smooth, clean edges against which to butt your acoustic wall treatments and bass traps for a more professional appearance.

Acoustically, they smooth out the excess low frequency energy that congregates in room corners.
