Waffle Diffuser Bundle (4 Sets) | QRD-Style Project Kit (Black)

⚡ Complete Project Benefits

  • ✅ Total Wall Solution: Includes 4 full panels to create a massive acoustic feature wall (Approx. 4ft x 4ft).
  • ☁️ Safe for Ceilings: Ultra-lightweight EVA puts zero stress on your ceiling. Won't hurt if it falls.
  • 💰 Bulk Savings: Best value for treating larger areas like rear walls or ceiling clouds.

Where to Place Diffusers? (Pro Advice)

You might think acoustic treatment belongs in front of you, but for diffusers, the magic happens behind or above you.

  • Option A: The Rear Wall (Most Popular): Placing this 4-Set Bundle on the wall behind your listening position scatters reflections, making your small room sound twice as big.
  • Option B: The Ceiling Cloud: As sound bounces between the floor and ceiling, it creates mud. Mounting these lightweight Black panels above your head adds "air" and clarity to your mix.

Design Your Soundstage (Layout Ideas)

With 4 full sets (16 modular pieces total), you have the freedom to design a professional acoustic landscape.

  • The "Big Square" (2x2): Combine all sets to make a massive 48" x 48" statement piece on your rear wall.
  • The "Panoramic Strip" (1x4): Install them in a long horizontal row at ear level to widen your stereo image.
  • The "Checkerboard": Mix these Black diffusers with Foroomaco Absorption Panels for a balanced, high-end studio look.

Why EVA Material? (QRD Technology)

Based on Quadratic Residue Diffuser (QRD) physics, these panels use math to scatter sound. We crafted them from High-Density Black EVA to solve the problems of traditional wood:

  • Ultra-Lightweight: Safe for overhead ceiling installation (Drill-Free).
  • Renter Friendly: Easy to stick with double-sided tape. No damage to walls.
  • Matte Black Finish: A sleek, professional aesthetic that blends into dark studio environments.
