Loudspeakers have special demands. Acoustic System's loudspeaker supports are constructed similar to the component supports, but they are trimmed to meet the needs of speakers. They will replace the speakers' standard spikes. The potential sound improvement is astonishing.
Effect: Even more contour in the bass, increased transparency and precision, more "swing in the hips".
