GAIA II is designed for floor standing speakers and subwoofers weighing up to 120 lbs (54Kg). Finished in an elegant machined dark chrome metal housing the GAIA II incorporates IsoAcoustics’ patented design principles to deliver extraordinary acoustic results. GAIA II provides a high degree of isolation while resisting lateral movement and oscillations to maintain alignment with the listening position. Internal reflections from the hard-supporting surface are attenuated resulting in greater sound clarity and openness.Optimal results are achieved by installing the GAIA isolators with the logo facing the listening position or rotated 180 degrees to align the isolators with the speaker’s motive forces. Lift and place the speakers into position as the GAIA lower isolators will adhere to the supporting surface.The GAIA’s are threaded into the base of the speaker or subwoofer to replace the existing spikes or feet. Threading the GAIA’s into the base of the speaker creates a strong connection with the speaker. With the top of the GAIA housing connected with the speaker and the bottom of the GAIA connected to the supporting surface all of the energy is then managed by the GAIA’s internal isolator.The GAIA II includes thread adaptors for sizes M6-1.0 M8-1.25 and ¼”-20.
