GIK Acoustics Alpha Series is a new line of acoustic panels and bass traps that combine effective acoustic treatment with stylish good looks. The 4A Alpha Panel Diffusor/Absorber is a hybrid treatment panel with a wood front cut with a mathematical sequence of slots for the one-dimensional scattering/diffusion of incident sounds waves.
Each 4A Alpha Panel measures 23.75 X 23.75 X 4-inches and is a wood-framed panel filled with rigid fiberglass absorption material. The panel is then wrapped in fabric and finished with a blonde wood veneer fascia. The slots in the wood face allow low frequency waves to pass through to the fiberglass panel for absorption.
I installed two pairs of 4A Alpha panels—two each, one above another in the front corners of my Tones 4 $ Studios. I screwed eyehooks into the back of each corner of the Alpha’s and then used tie wraps to secure the panels to eyehooks in the walls.
After measurement with Room EQ Wizard, the Alphas outperformed the old corner treatments with more reduction of the decay below 70Hz. In addition, I was now enjoying extra diffusion via the panel’s front wood faces, and I love the great look of the 4A Alphas panels in my corners.
The 4A Alpha Panel Diffusor/Absorber Panels come in bundles of four and sell for $340.
