Trying to control the amount of “boominess” on stage from bass guitar, kick drum, big guitar amps, synth basses, and the like?
Call your Gramma! The Auralex GRAMMA and Great GRAMMA (the Great Gramma is sized for bigger rigs, up to 300lbs.)4, that is. These two units are isolation platforms intended to stop the transfer of low frequencies from a speaker (or speakers) into the floor or stage they’re sitting on.
