ISO-155 Isolation stands for medium sized speakers and studio monitors The ISO Stands are the latest generation of IsoAcoustics stands designed for studio monitors. The ISO Stands are an updated version of the popular ISO-L8R series and features a lower profile, new frame design and a newer version of isolator for improved performance. The ISO-155 isolation stand is 6.1” (155mm) wide x 7.5” (190mm) depth and is rated for monitors weighing up to 40lbs. Offering 14 variations of height and tilt, the ISO-155 will help you optimize the placement of your monitors and bring your tweeters to ear level. The IsoAcoustics patented isolation system provides superior isolation and decoupling from the supporting surface. The stands are biased to keep all energy in alignment with the speaker cones, providing greater clarity and focus. Specifications Dimensions Short Setting (WxDxH) 6.1” x 7.5” x 3 (155mm x 190mm x 76mm) Dimensions Tall Setting (WxDxH) 6.1” x 7.5” x 8.2 (155mm x 190mm x 210mm) Tilt up to 6.5 degrees Weight Cap Short setting 40lbs (18KG) Weight Cap Tall setting 35lbs (16KG) Quantity 2 Stands (1 Pair) Optimize speaker placement and focus An important aspect of the speaker stand design is the ability to adjust the height and tilt angle of the supported speaker enclosure to optimize its position relative to the listener and eliminate soundwave reflections off the supporting surface. In a typical Desktop Audio Workstation (DAW) configuration, the listener is positioned 3 to 4 feet from the monitors with ear level approximately 20″ above the work surface. Raising and tilting the monitors to the optimum position can be achieved in these circumstances using the IsoAcoustics stands. Exciting the supporting surface The isolators manage the energy of the speaker to reduce vibrations resonating through the supporting surface to eliminate dissonant sounds in the listening area or joining rooms. Reducing internal reflections Internal reflections are vibrations reflecting back up the speaker cabinet which causes  smear . Smear is a result of artifacts replicated in both channels which are perceived to be in the middle, causing the stereo image to collapse. The IsoAcoustics isolators reduce internal reflections to eliminate  smear . The result is an improved stereo image of natural spatial sound.
