The hex panel that scatters sound in every direction at once — triangulated oakwood facets break echo into many small reflections instead of bouncing it back at you in one flat wave. Decor-grade looks, NRC 0.64, M1 fire-rated.
★ 4.86 / 5 from 14 verified buyers — 93% gave it 5 stars. The strongest review ratio in the Diffuse PRO line. Why Diffuse PRO Isometric Triangle Hexagon is different Polyhedral diffusion — triangulated facets inside a hexagon scatter sound on multiple axes, not just one. Absorber + diffuser in one panel — foam core kills echo, wood face scatters reflections. No paired diffuser needed. NRC 0.64 — absorbs ~64% of mid/high-frequency sound energy on contact. Scattering 200 Hz – 5 kHz — works across the full speech and music range. M1 fire-rated (Euroclass E) — meets commercial install code for studios, offices, restaurants. Hexagon tileable — full coverage with zero gaps, or stagger for a feature wall. 10 wood finishes — match the room you actually work in. How it works — polyhedral diffusion, explained ABSORPTION Foam core kills echo M1 fire-class foam behind the wood face captures mid- and high-frequency energy, cutting reverb on contact.
DIFFUSION Triangulated facets scatter sound Each hex contains multiple triangular faces angled in different directions. Sound hits, splits, and scatters on many axes — not one.
TILES SEAMLESSLY Hexagons cover walls cleanly The hex geometry tiles edge-to-edge with no gaps. Build a wall, a feature panel, or a staggered pattern.
Standard foam panels only absorb. Linear-groove diffusers scatter on one axis (left-right or up-down). Triangulated hex diffusers scatter on many axes at once — which is why this design is preferred in live recording rooms, drum rooms, and vocal booths where you need broad-band scatter from a single panel.

What's in the box 6, 12, or 24 Diffuse PRO Isometric Triangle Hexagon panels (selected pack ) 11.8 × 10.2 × 0.4 in / 30 × 26 × 1 cm each Selected oakwood / MDF finish Install (mounting hardware sold separately) Install in 4 steps 1 Plan the layout Lay panels on the floor first. Hexagons tile edge-to-edge for full coverage, or stagger them for a feature wall. Photograph before mounting.
2 Choose your mount Construction adhesive for permanent installs. Heavy-duty Command strips or Z-clips for rental-friendly mounting.
3 Mount the panels Press firmly for 30 seconds. Start at the top of the layout and work down. Match facet orientation if you want a regular pattern; rotate randomly for maximum scatter.
4 Treat first-reflection points For studios and listening rooms, prioritize panels at the first-reflection points on side walls and behind the listening position.
Made for Live recording & drum roomsMulti-axis scatter keeps the room lively without flutter — drums don't ring, vocals don't go dead. Vocal booths & podcast roomsKills flutter between parallel walls; broadband scatter makes the mic capture sound natural. Listening rooms & home theatersCleaner stereo image, no slap-back, no "dead-room" sterility from over-absorption. Modern offices & design-led restaurantsM1 fire class meets commercial code.

Frequently asked questions Will this block noise from my neighbor or the street? No. This panel is an absorber + diffuser. It reduces echo and scatters reflections inside a room. Blocking noise through a wall requires mass — extra drywall, mass-loaded vinyl, or a sealed door. Anyone selling a 1 cm foam-and-veneer panel as "soundproofing" is misleading you. What does "polyhedral" or "multi-axis" diffusion actually mean? A flat wall reflects sound back in one direction. A linear groove scatters it on one axis (left-right or up-down). The triangulated facets on this hex face are angled in many directions, so incoming sound splits and scatters on multiple axes at once. That's why it works better in live rooms and drum rooms where flutter can come from any wall. How many panels do I need? For most home studios and offices, cover 20–30% of reflective wall area. Rough : small booth or office → 6–12 panels. Mid- studio or vocal room → 12–24 panels. Drum room, auditorium, or large feature wall → 24+ panels (multiple packs). Hexagons tile edge-to-edge, so you can build any shape. 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 geometric thickness would crack and × more. Veneer gives the same look at a usable and price. Can I install this myself? What about rentals? Yes. For permanent installs, construction adhesive or screws into wall anchors. For rentals, heavy-duty 3M Command strips, 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. Can I tile the hexagons or do I have to stagger them? Both work. Hexagons tile edge-to-edge with zero gaps for full-coverage walls. Staggered or partial layouts make a feature wall. For maximum scatter, rotate every other panel so the facets point different directions. Will it work on brick, concrete, or textured walls? Yes — with the right hardware. Use masonry anchors and screws for brick and concrete. For heavily textured drywall, construction adhesive bonds better than tape-based mounting. The panels themselves are rigid and flat-backed, so the wall surface determines the mount. 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. 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.
