A SKU-first catalog of reflection filters, bass traps, monitor isolation pads, vocal booths, and panel kits. Every product ships with a serialized frequency-response card, an NRC rating measured at 125 Hz–4 kHz, and a 30-day in-room money-back guarantee. Filter by room size, frequency band, and absorption rating — not by lifestyle photography.

Every RMuff panel is tested at 125 Hz–4 kHz against ASTM C423 in a third-party NRC-certified chamber. SonicCore™ posted 3.2× the broadband absorption of standard foam in 2023 validation — and we publish the curve with every serial number.
RMuff supplies 380+ commercial studios in 14 countries, including 11 Dolby Atmos-certified rooms. Trade accounts get tiered pricing from 5 units, white-glove install coverage in the NYC tri-state area, and the lifetime re-cover program: every acoustic panel can be refaced at our NJ shop for $0 in materials, for as long as you own the room.
NRC (Noise Reduction Coefficient) is the average absorption across 250 Hz, 500 Hz, 1 kHz, and 2 kHz per ASTM C423. It tells you how much energy a panel removes inside a room. STC measures sound transmission between rooms — useful for walls between apartments, mostly irrelevant inside a single control room. We publish NRC for every product because that's the metric a mix engineer can act on. RMuff panels range NRC 0.65 to 1.20.
Use our free Room Analysis Tool: upload a phone frequency sweep, answer six questions about your room dimensions and primary use, and we return a custom treatment plan in under four minutes. As a rule of thumb, bedroom studios under 15 m² need 6–8 m² of treatment, project studios 15–30 m² need 10–14 m², and control rooms over 30 m² need a measured plan plus bass-trap coverage at every trihedral corner.
Every panel ships with printed install docs and a torque-spec card. Wall panels mount with the included AX-Series brackets and standard drywall anchors — most bedroom and project studios install in under three hours. For the NYC tri-state area we offer white-glove install through our NJ shop. Trade-account integrators get co-branded install documentation for client sign-off.
Order any RMuff product, install it in your room, and listen for 30 days. If the measured performance — verified by a before-and-after frequency sweep — doesn't match the published NRC card for your SKU, we pay return shipping and refund 100% of the purchase price. No restocking fee. No "customer must ship in original packaging" fine print. The pro-line panels also carry a 10-year performance warranty against delamination and absorption drift.
