[QUOTE="marantz123, post: 944590, member: 16849"] Consider the condition of the surrounds, esp since being unused for an extended time, be it foam or rubber, they go through changes, either hardening or becoming softer and sticky and this also occurs unevenly such that you have an uneven mechanical response which could cause a distorted pistonic movement of the coil/motor section. Check if they run a bit better in a horizontal position rather than a vertical position, and rotate the driver in the vertical position to see if the noise clears up at a point. If they are paper surrounds, then this may not be applicable. [/QUOTE]
