Royer Labs RSM-SS24 is a patented Sling-Shock suspension shockmount designed for microphones approximately 38 mm (1.5 inches) in diameter, with a tolerance of +/- 1/8 inch — including the Royer SF-2, SF-24, and SF-24V, and other cylindrical microphones of similar size. The RSM-SS24 is the mid-size model in Royer's Sling-Shock line: the smaller RSM-SS1 handles 1-inch diameter microphones (Royer R-121, R-122, SF-12), and the larger RSM-SS251 accommodates 2-inch diameter microphones (Telefunken ELAM 251, Neumann U-67, U-87). Like all Sling-Shock models, the RSM-SS24 completely eliminates rubber and elastic suspension elements — replaced by a system of non-resonant nylon cord and damped steel springs. Hand-built from aircraft-grade aluminum at Royer's Burbank, California facility.
Nylon and springs instead of rubber — isolation without material degradation
Conventional shockmounts rely on elastic bands or rubber supports that degrade over time, lose tension, and require replacement — with loose mic retention creating fall risk in the process. The RSM-SS24 addresses this at the design level: the nylon-and-damped-steel-spring suspension does not age, requires no maintenance, and needs no replacement parts. Isolation covers vibrations transmitted through the stand (appearing as rumble and broadband disturbances), physical shocks, and mount self-resonance — the last problem being particularly relevant in high-SPL applications, where mechanical resonance of the mount itself can introduce intermodulation artifacts into the recording. A built-in cable clip reduces additional vibrations conducted through the microphone cable. The adjustable grip with a knurled lock-down knob allows secure, precisely positioned retention; the chamber interior is lined with felt or soft cotton to protect the microphone's finish.
Compatibility and position in the line
The RSM-SS24 accommodates cylindrical microphones approximately 38 mm (1.5 inches) in diameter, +/- 1/8 inch. Dedicated Royer models: SF-2, SF-24, SF-24V. The Royer R-10 can also be mounted in the RSM-SS24 after removal from its threaded swivel mount. The shockmount fits other microphones of similar cylindrical diameter as well. The RSM-SS24 is compatible with standard microphone stands (European stand adapter included where applicable). Unconditional lifetime warranty.
