Page 4: Installation Options
The AD-S28Tw has been designed for installation flexibility. The subwoofer may be mounted using a number of different suspension techniques, as well as being easily shelf or floor mounted. The QSC logo on the grille is rotatable to accommo- date horizontal or vertical orientation. While low frequency products do not have directional dispersion characteristics, all of the sonic energy produced by this subwoofer exits the cabinet through the port due to the ported bandpass design. - Page 5 Once the subwoofer is secured in position, the QSC logo can be rotated if desired.

Be sure to leave less than 12 in (300 mm) of slack in the secondary attachment cable. the safety/seismic secondary attachment must be secured to structure that is capable of supporting the weight of the subwoofer and must be connected using load rated hardware.
- Page 7 The locations of the eyebolts were designed to suspend the subwoofer using the fewest number of attachment points. Where possible there are only three attachment points to be used. These points are located so that the triangle they form “encloses” the center of gravity and the subwoofer will balance with all three points suspended. In some cases, one or more of the attachment points is not on a cabinet side that is facing up.
