Fully Flown WPM Arrays
WPM cabinets can be combined with MSX Passive subwoofers to form full-range flown arrays in two possible configurations:
twelve WPM cabinets plus three MSX Passive subwoofers, or a subwoofer-only configuration of up to eight MSX Passive.
The MLA Mini Flying Frame is used to support the full array. Fully flown systems always have the subwoofers at the top of the
array, with the WPM cabinets suspended underneath from a Transition Frame attached to the lowest subwoofer. The example
illustrated here is an array of two MSX Passive subwoofers and eight WPM cabinets.
” With an MSX Passive subwoofer on its wheelboard, begin by attaching the Flying Frame to the cabinet. Extend the four
dropdown brackets on the Flying Frame and engage them into the four slots in the top of the sub. The front edge of the
Flying Frame should be aligned with the front face of the MSX Passive. Secure in place with four Rigging Pins.

” Attach the suspension cable(s) to the Flying Frame using shackles. If using single-point suspension, attach the chain hoist
to the suspension hole of the Flying Frame indicated in DISPLAY 2.3 and raise the MSX Passive upwards. With two-point
suspension, attach the hoists to the front and rear suspension points. Raise the hoist(s); remove the wheelboard when it is
clear of the ground.
