The Recoil stabiliser does this with 4 separate layers that each serve a purpose to eliminate various issues. At the base of the stabiliser is the traditional isolation foam that eliminates resonance through the desk surface. On top is a laser cut steel platform that adds weight and stability to hold the monitor rigid in place. on the front they designed a curved panel that eliminates standing waves. Finally the top has a non-slip neoprene surface that offers grip to the loudspeaker and ensures maximum signal transfer to your ears.
Recoil Stabilisers are available in a number of sizes to suit your speaker size and setup. The RX7-HF is a "horizontal fire" stabiliser for monitors that have roughly 7" drivers.
