The engineer's choice in the Diffuse PRO line — diagonal slats steer reflections off-axis, away from the listening position. Decor-grade oakwood face, M1 foam core, NRC 0.64. Directional acoustic treatment that looks like wall art.
Why Diffuse PRO Diagonal Square is different Install in 4 steps 1Plan the layout Lay panels on the floor. Alternate slat direction (one panel angled one way, the next mirrored) for a chevron pattern, or keep them parallel for unified motion.
2Choose your mount Construction adhesive for permanent installs. Heavy-duty 3M Command strips or Z-clips for rental-friendly mounting (panel is 2.2 lb / 1.05 kg each).
3Mount the panels Press firmly for 30 seconds. Start at the top of the layout and work down. Use a level for grid alignment so the diagonal pattern reads cleanly.
4Aim the slats at the first reflection For mixing rooms: orient slats so reflections steer away from the listening position. This is the whole reason the diagonal version exists. Mark mirror points and angle accordingly.
Made for Mixing & mastering roomsSteers first reflections off the mix position — tighter stereo image without going dead. Asymmetric home studiosSpare-bedroom rooms with weird angles benefit more from directional than symmetric treatment. Listening rooms & home theatersCleans up the sweet spot without killing the air in the room. Design-led commercialRestaurants, hotel lobbies, conference rooms — the diagonal motion reads as intentional design, not soundproofing.

Frequently asked questions What does "directional" diffusion actually mean? A symmetric panel scatters sound roughly evenly in every direction. The diagonal slats on KK1308 are asymmetric — they tilt the scatter pattern off the perpendicular axis. In a mixing room, that means you can aim the first reflection away from your head instead of bouncing it back. Same NRC as the square Diffuse PRO, different geometry, different job. How is this different from the standard Diffuse PRO (KK1247)? Same NRC (0.64), same scattering range (200 Hz – 5 kHz), same materials, same fire class. The only difference is the slat geometry — KK1247 is symmetric, KK1308 is diagonal/directional. Pick KK1308 for first-reflection-point treatment in asymmetric rooms, mixing positions, or anywhere the room shape isn't a perfect rectangle. Will this block noise from my neighbor or the street? No. Diffuse PRO Diagonal is an absorber + diffuser. It reduces echo and breaks up reflections inside a room. Blocking noise through a wall requires mass — extra drywall, mass-loaded vinyl, or a sealed door. Anyone selling a 2-inch foam panel as "soundproofing" is misleading you. How many panels do I need? For most home studios and offices, cover 20–30% of reflective wall area. Rough : small booth or office (8 × 10 ft / 2.4 × 3 m) → 6–12 panels. Mid- studio or restaurant section → 12–24 panels. Auditorium or large room → 24+ panels (multiple packs). For mixing rooms, prioritize panels at the side-wall first-reflection points before filling out the rest of the room. Is the wood face real oak? The face is laminated MDF with oakwood veneer — same construction used in commercial acoustic panels and high-end furniture. Solid oak at this diagonal slat thickness would crack and × more. Veneer gives the same look at a usable and price. Can I install this myself? What about rentals? Yes. Each panel is 2.2 lb / 1.05 kg. For permanent installs, construction adhesive or screws into wall anchors. For rentals, heavy-duty 3M Command strips rated for 4–5 lb each panel, or Z-clip brackets that lift on and off. Mounting hardware is sold separately so you can match the wall. Is this safe for commercial spaces — restaurants, offices, schools? Yes. The panel is M1 fire-rated (Euroclass E), which meets commercial fire-safety code in most EU and Asian markets. Always confirm specific local requirements with your fire marshal or architect before installing in public assembly spaces. How long does shipping take? Handling 1–2 business days, then standard shipping 7–14 days to the US and most countries (free worldwide on orders $99+). Express shipping is at checkout — 7 days or less to most destinations. What's your return policy? 100-day guarantee. If the panels don't deliver the acoustic or visual result you expected, contact support within 100 days for a full refund. Bulk B2B / contractor orders (100+ panels) follow a separate policy — contact us before placing the order. How do I clean the wood face? Dry microfiber cloth for dust between the slats. Slightly damp cloth (water only, well-wrung) for the rare smudge. No solvents, no furniture polish, no spraying — the veneer and the foam core both prefer dry treatment.
