12 inch Studiofoam corner acoustic absorbers. 12" x 12" x 24" - 1 per box (2 linear feet - not pictured).
CornerFills are sections of flat-cut Studiofoam corner acoustic absorbers that are beneficial in two ways. Aesthetically, they give you smooth, clean edges against which to butt your acoustic wall treatments and acoustic foam bass traps for a more professional appearance. Acoustically, they smooth out the excess low frequency energy that congregates in room corners.
Available in Charcoal Gray, Purple, Plum, Forest Green, Kelly Green, Blue, Orange, Red, Burgundy, and Brown.
