IsoAcoustics ISO-Pucks package of two
Iso acoustics ISO-Pucks are designed to be used in multiples to match the weight of each speaker. Each unit is rated for up to 20lbs (9kg) so multiple units can be placed under each speaker. For smaller studio monitors 3 ISO-Pucks can be used, 2 front and 1 back. For heavier speakers and guitar amps, 4 or more units can be used.
The ISO-Pucks are designed to be used with the logo facing forward, as the isolators have been tuned to resist lateral movements resulting in greater clarity and focus.
