The angled Primacoustic RX5a Recoil Stabilizer is a unique speaker mounting device that eliminates disruptive resonant coupling from the loudspeaker to the stand. At the same time the Recoil Stabilizer provides a stable base that reduces recoil from the loudspeaker's forward energy.

Made from three basic components, the Recoil Stabilizer is essentially a platform for the loudspeaker that features a high-density urethane base that isolates the speaker from the shelf, monitor-bridge, or stand. This effectively decouples the loudspeaker to eliminate vibration-borne resonance to the substructure. A heavy laser-cut steel plate is added and sandwiched between the isolation layer and a no-slip neoprene top. The steel plate introduces significant mass to the structure and serves to stabilize the speaker.

By reducing the backward recoil energy as the speaker coil pushes energy forward, initial waveform transients no longer suffer lag and the sharpness of the resulting pulse is more defined. The result is significantly greater detail at all frequencies, with tighter bottom end and improved depth of field.
