This pair of IsoAcoustics ISO-L8R130 Small Studio Monitor Isolators prevent the transfer of speaker cabinet energy to surrounding surfaces, effectively isolating the speaker. By allowing the speaker to perform in free space, it's able to sound the way it was intended.
The height and tilt angle of the ISO-L8R130 are adjustable to optimize speaker positioning relative to the listener. The 2 included sets of height tubing along with 2 sets of end-plug pairs provide 14 steps of height adjustment. The different combinations are used to tilt the speaker up and down. The stand can be assembled and reconfigured repeatedly to establish the ideal position.
The ISO-L8R130 isolators are designed to support small monitor speakers no heavier than 20 pounds. They can be set to raise your speakers either 2.5" or 8" from the supporting surface.
