This solution results in a multifaceted surface. Each acoustic panel has six angled grooves, and milled half grooves along the outer edges. This results in continuous straight grooves at the joints between panels, and an elegant combination of angled and straight grooves.
If the panels are installed in offset rows, you can choose to have some of the angled grooves continue between rows. You can also freely vary the offset, or turn some panels 180 degrees, to give the design a different rhythm.
