The Wilson Audio Subsonic is the fraternal twin of the WAMM Master Subsonic. It features the same subwoofer drivers and the same internal volume. The differences lie in the finish details. The metal work in the WAMM Master Subsonic features the prismatic finish that mirrors (no pun intended) the WAMM’s main array gantry. On the Wilson Audio Subsonic, the metal work is from Wilson’s main line finish process—the same level of metal finish that has adorned Wilson products throughout the line.
