Section E: Large Array Frame with Extender Bars for Cardioid Subwoofer

The Large Array Frame with Extender Bars (Short or Long) can also be used to mount RoomMatch subwoofer modules behind the
primary array. The most common usage for this application is to provide a cardioid pattern for subwoofers with one subwoofer module
directly behind the front subwoofer module. For this application, follow these steps:
1. Use RoomMatch™ Array Suspension Angle Calculator software to determine the hole positions on the array frames and/or
Extender Bars for required aiming angles and confirm load limits are not exceeded.
2. Place array frame directly under the chain motors positioned for intended array location.
3. Locate the 2 extender bars noting the R (right) and L (left) markings on the labels.
4. From the rear of the Large Array Frame, insert the bar marked L into the Left pocket of the array frame. Note: the double rows of
mounting holes should be facing upward and on the outside of the frame.
5. Align the bolt holes with the intended position marker (OUT or IN) of the bar.
6. Insert 4 bolts (2 per side) and finger tighten each until all bolts are installed.
7. Repeat steps 3 to 6 for the R bar into the Right pocket of array frame.
8. Attach 5/8 –inch forged steel frame shackles to array frame in hole positions determined by aiming software.
9. Lower chain motors and attach to shackles installed on array frame.
10. Raise array frame to height slightly greater than that of the subwoofer module.
11. Install RMSFLY side plate kit to RMS215 subwoofer modules following steps included with RMSFLY kit.
12. Position front RMS215 module directly under Large Array Frame
13. Position rear RMS215 module directly under mounting-hole tabs of Extender Bars
14. Lower the Array Frame/Extender Bar assembly to align the front holes of the Array Frame to the front holes of the front subwoofer
module side plates. Insert an alignment punch into the rear holes of the front subwoofer side plates.
15. Thread 2 bolts (1 per side) into the front side-plate holes of the front subwoofer and finger tighten.
16. Lower the Extender Bars to align the rear holes of the Extender Bars to the rear holes of the rear subwoofer module side plates.
Insert an alignment punch into the front holes of the rear subwoofer side plates.
17. Thread 2 bolts (1 per side) into the rear side-plate holes of the rear subwoofer and finger tighten.
18. Remove alignment punches and thread 2 bolts (1 per side) into the front side plate holes of the rear subwoofer and finger tighten.
19. Thread 2 bolts (1 per side) into the rear side plate holes of the front subwoofer and finger tighten.
20. Tighten all 8 bolts with socket tool using torque of 35 to 40 foot-pounds (47 to 54 Newton-meters).
21. Raise array assembly to height slightly above that of the next array module to install.
22. To install additional modules suspended from the side plates of the front subwoofer module, follow steps 6 to 20 as outlined in
Section A of this document.
