Their unique male/female configuration helps solve quite a wide range of acoustical problems. Because they offer a significant amount of both low frequency control & broadband absorption, they work well in rooms that don't have corners available for treatment with LENRDs or where you don't need or desire large expanses of absorbent wall treatment. The female Sunbursts are often cut in half & used as mini-LENRDs or to frame Studiofoam-treated areas. Customers love 'em & so will you!
