    IF just reducing level solved the problem great, though shock and vibration are separate issues.
    Because the woofer itself transfers energy to surrounding structure:

    There are techniques for suppression; shock mounting and dampening.
    The goal is to move air, not make a "rump-kicker"

      I would use some decoupling mounts of some type. A search for neoprene decoupling pads on google has some interesting options. I'd un-bolt the sub from the front panel, then use a set of the floor mount isolators to mount the sub to the bottom of the cabinet about 1/2" or so back from the front panel.

        It is starting to look a redesign of subwoofer is inevitable. I will have to remove the front face to cut a bigger hole for the sub to push air through from 1/2" away. I will also have to make another box for the sub. The box barely fits in the cabinet and its contents barely fit in the box . I definitely went too big on the sub. I think I will have to downsize. I should have picked the Dayton Audio SA100 instead of the Yung SD300. Would the SA100 drive the UMB-22-8 or will I have to downsize the subwoofer as well?

        What is the criteria for choosing neoprene pads?

          I forgot to mention the sub is giving me a buzzing noise. It is intermittent but very annoying. Would a grounded cable take care of that?
