Experience reduced echoes and enhanced speech clarity.

Zintra Quadratic sticks are designed to enhance acoustics through the innovative use of a quadratic residue sequence. Variable heights strategically enhance sound absorption while minimizing reverberation, ensuring a more evenly distributed sound energy throughout the room.

Each pattern comprises 8 sticks, repeating systematically to optimize outcomes.

Suitable for both ceiling and wall applications, Zintra Quadratic Sticks redefine acoustic performance with precision engineering.

Available in narrow width and a variety of finishes tailored to your aesthetic preferences.
