Quiet your room in one afternoon

KK1471 is Arrowzoom's Series PRO pyramid foam — engineered for home studios, podcast rooms, drum rooms, and gaming setups where thin 2″ foam doesn't cut it. With NRC 0.92 across the speech and music bands, it absorbs reflections that cause echo, flutter, and that boxy "small room" sound. Pick the 4″ (10cm) tile for vocals and speech, or step up to 6″ (15cm) when you need to tame low-mid bass build-up.

How acoustic foam actually works

Sound waves carry energy. When they hit a hard wall, most of that energy bounces back into the room — that's the "echo." Acoustic foam converts that energy into a tiny amount of heat inside its open-cell structure. The thicker and denser the foam, the lower the frequencies it can absorb. 1″ foam handles high frequencies only. 4″ handles mids. 6″ reaches into the low-mids where bass guitar, kick drum, and male vocals live.

What NRC 0.92 actually means

NRC (Noise Reduction Coefficient) is a single-number score from 0 to 1 — the fraction of sound energy a panel absorbs. Higher = quieter room.

NRC 0.30–0.45 — cheap 1″–2″ foam. Slight high-frequency damping only.
NRC 0.92 (KK1471) — studio-grade. Removes 92% of reflected energy in the test band.
NRC 0.95+ — professional broadband absorbers (4× the price).

Why KK1471 beats $19 Amazon foam

Spec	KK1471 (Series PRO)	Typical $19 Amazon foam
NRC rating	0.92 (tested)	0.30–0.55 (often untested)
Thickness	4 in / 6 in (10/15 cm)	1 in / 2 in (2.5/5 cm)
Density	30 kg/m³ (1.87 lb/ft³)	8–12 kg/m³ (0.5–0.75 lb/ft³)
Fire rating	Class B retardant	Usually none
Bass control	Yes (6″ reaches 125 Hz)	No — thin foam ignores bass
Color options	8	1–2
Guarantee	100 days	None or 30 days

Translation: Two cheap Amazon packs cost the same as one KK1471 pack — but absorb half the energy, ignore bass frequencies entirely, and aren't fire-rated. KK1471 is the panel professionals reach for when "good enough" isn't.

Install in 5 steps

Unpack and rest. Lay tiles flat for 24 hours so any compression marks from shipping decompress.
Mark the wall. Identify the first reflection points (front wall, side walls at ear height, ceiling above mix position).
Apply adhesive. Spray adhesive or 3M Command strips on the back of each tile. For renters, use removable strips.
Press and hold. Press firmly for 30 seconds. Work in a grid for clean alignment.
Test the room. Clap once at your mix position. If the slap-back is gone and your voice sounds dry, you're done. If not, add more panels at the corners.

Made for

Home recording studios and vocal booths
Podcast and streaming setups
Drum rooms and rehearsal spaces
Gaming and YouTube content rooms
Home theaters with bass-heavy systems
Karaoke rooms and music practice rooms

Frequently asked questions

How many tiles do I need for my room?

Cover 20–40% of total wall surface for speech and podcasting; 40–60% for music recording and mixing. A 10×10 ft (3×3 m) room typically needs 24–48 tiles, focused on the first reflection points around the listening position.

What's the difference between 4″ (10cm) and 6″ (15cm)?

4″ handles speech, vocals, and high-mids — best for podcasts and voice. 6″ reaches into the low-mid bass band (down to ~125 Hz) — choose it for drum rooms, mix rooms, and any space where bass build-up is a problem.

Does this soundproof my room from neighbors?

No — and no acoustic foam does. Foam controls echo *inside* the room (absorption). Stopping sound from leaving the room is *soundproofing* and requires mass: drywall, mass-loaded vinyl, decoupled walls. KK1471 will not stop your neighbor from hearing your drums; it will make your drums sound dramatically better inside the room.

Is the foam fire-safe?

Yes. KK1471 is Class B fire-retardant and self-extinguishing — it will not sustain flame after the ignition source is removed. Always follow local building codes when installing on commercial or rental properties.

How do I install it without damaging my walls?

Use removable 3M Command strips or peelable adhesive squares. They hold the tiles firmly and remove cleanly when you move out. Avoid permanent spray adhesive on rented walls.

How long does shipping take?

Handling: 1–2 business days. Standard shipping: 7–14 days to the US and most countries (free on orders $99+). Express: 7 days or less.

Can I cut the tiles?

Yes. Use a sharp utility knife or electric carving knife. Cut on a flat surface with a straightedge. Pyramid tops can be trimmed flush for tight corners.

Will the color fade?

Polyurethane foam will yellow over years if exposed to direct sunlight or strong UV. For rooms with windows, the Black and Gray options hold their color best. Pearl White and Yellow show aging soonest.

How does this compare to Auralex or other studio brands?

KK1471 matches NRC and density specs of $4–$6/tile name-brand studio foam at roughly half the cost. The trade-off: those brands have larger US distribution and faster local replacements; KK1471 ships from our US warehouse but offers the 100-day guarantee instead.

Is it safe around kids and pets?

Yes — the foam is non-toxic. Install tiles above pet reach to avoid chewing; loose foam pieces are a choking risk for small animals and toddlers.
