    CURVE diffusors™ - Phase-Coherent diffusion, built in bass trap, mid-high internal absorber

    The CURVE System™
    Natural Sound. Architectural Style. Acoustic Precision.

    The CURVE Diffuser System™ offers an elegant and high-performance solution for designing acoustically accurate spaces. All three models of industry leading diffusors seamlessly blend acoustic performance with design flexibility—making them ideal for studios, listening rooms, performance spaces, commercial interiors, and high-end residential environments.

    The Curve Diffusor is an innovative, phase-coherent design with a constant-radius curve that ensures natural, even diffusion without the phase grating or distortion common in traditional quadratic-residue diffusors. An integrated mass loaded vinyl membrane bass absorption extends its performance into low frequencies, addressing both mid-high frequency diffusion and low-end control in one elegant unit.

    Product Benefits:

    • Dual-function acoustic control: Diffuses mid-to-high frequencies (300Hz–20kHz) and absorbs low frequencies (40–300Hz) via built-in mass loaded vinyl membrane
    • Safe, sustainable materials: No fiberglass or foam; filled with recycled cotton acoustic core
    • Flexible configurations: Modular 42" height allows stacking or alternating orientations on walls and ceilings
    • Architecturally refined: Available in a range of standard colors, premium fabrics, and wood veneers to match any design aesthetic
    • Easy installation: Comes with mounting cleats and hardware; optional floor stands available
    • No compromise in performance: Eliminates flutter echo, standing waves, and phase distortion

    Curve System Components:

    • Curve Diffusors (with vinyl diaphragmatic absorber membrane):
      • Small: 1" wide x 42” tall × 5" deep (custom options available, call for details)
      • Medium: 21"wide x 42” tall × 7" deep (custom options available, call for details)
