Your door is treated. Your walls are next.
Treating the door alone is a great start. But sound bounces off every hard surface — and walls are the biggest reflectors in the room. The Wall Kit PRO is the natural companion to the Door Kit PRO: same quality polyester fiber, same peel-and-stick install, designed to match. Twenty minutes and your walls go from reflective to absorptive.
🛡️ 100-day guarantee 📦 $99+ 👥 300,000+ customers How it works 🎧 Absorption, not blocking The panels soak up mid- and high-frequency sound reflections from your walls. The result: less echo, a shorter reverb tail, and a cleaner room sound. It's not about blocking outside noise — it's about controlling what's happening inside.
📐 Coverage beats perfection You don't need to tile every inch. 30–50% of your wall surface in a smart pattern delivers most of the acoustic benefit at a fraction of the cost. Start with the wall behind your desk or behind the speakers.

👥 300,000+ customers worldwide · ⭐ 4.7 / 5 rated Frequently asked questions How is this different from the Door Kit PRO (KK1244)? The Door Kit PRO (KK1244) is engineered to treat your door: thicker panels, higher mass, STC-rated for blocking sound at the entry point. The Wall Kit PRO (KK1259) is designed for your walls: thinner, lighter, optimized for absorption and coverage area.
They're complementary — door blocks, walls absorb. Together they give you a complete room treatment.
Can I use these without the Door Kit PRO? Absolutely. They work as standalone wall panels in any room. The Door Kit PRO connection is about completing a full room treatment — it's a recommendation, not a requirement.
Will these stop noise from the apartment next door? No. These are absorption panels — they reduce echo and reverb inside your room, not noise passing through walls from an adjacent space.
For soundproofing between rooms you need mass-loaded vinyl, resilient channel, or full wall assemblies. These panels won't help with that.
What does 30–50% coverage mean in practice? In a 12×12 ft room, 30–50% coverage is roughly 52–86 sq ft of panels. That's 2–3 packs of 24 placed thoughtfully: primary reflection points, behind your desk, and behind your speakers.
You don't need every wall tiled. Smart placement beats full saturation every time.
Will the adhesive damage my paint? On flat painted drywall, panels are removable with care but may pull paint after extended time — especially if the paint is old or thin. On textured, wallpapered, or bare drywall the adhesive won't grip reliably.
For those surfaces, use double-sided mounting tape or hook-and-loop strips instead of relying on the built-in adhesive.
Can I paint or dye these? No. Paint or dye clogs the polyester fibers and kills acoustic absorption — the panels need open fiber structure to work. Choose your color at order time. 7 options are .
Are they fire-rated? Polyester panels are treated to resist ignition. For commercial installs — offices, schools, professional studios — request our certified lab report. Fire code requirements vary by jurisdiction, so confirm your local spec before ordering for commercial use.
Can I cut these to fit corners or outlets? Yes. Scissors or a utility knife, straight edge optional. Polyester cuts cleanly without fraying. No special tools needed — just mark and cut.
What if my room still sounds bad after installation? Try these three things first: increase coverage toward 50%, focus panels on primary reflection points (the wall your speakers face, the wall behind your desk), and add something in the corners — bass traps address low-frequency buildup that wall panels alone won't fix.
Still unhappy? The 100-day guarantee is real — return for a full refund.
What's the smell when the box arrives? A light factory smell that airs out within 24–48 hours. Polyester panels are non-toxic with no harmful off-gassing — it's just new material in a sealed box. Leave them out in a ventilated room overnight and the smell is gone.
