QuickFly Rigging
The ULTRA-X40 and ULTRA-X42 loudspeakers are compatible with Meyer Sound’s QuickFly system, a comprehensive collection of custom-designed rigging, flying, and mounting options. Comprised of rugged, reliable, and easy-to-configure components, QuickFly lets you deploy ULTRA-X40 and ULTRA-X42 loudspeakers as either individual loudspeakers or as arrays at precise angles to take full advantage of their directional components.
Important Safety Considerations
When installing Meyer Sound loudspeakers and subwoofers, the following precautions should always be observed:
All Meyer Sound products must be used in accordance with local, state, federal, and industry regulations. It is the owner’s and user’s responsibility to evaluate the reliability of any rigging method for their application. Rigging should only be carried out by experienced professionals.
Use mounting and rigging hardware that has been rated to meet or exceed the weight being hung.
Make sure to attach mounting hardware to the building’s structural components (roof truss), and not just to the wall surface.
Make sure bolts and eyebolts are tightened securely. Meyer Sound recommends using Loctite® on all threaded fasteners.
Inspect mounting and rigging hardware regularly. Immediately replace any worn or damaged components.
Rigging Points
The top and bottom faces for the ULTRA-X40/42 cabinet include high-strength, corrosion-resistant stainless steel points that provide M8 x 1.25 threaded holes for easy connection to QuickFly rigging and third-party mounting options.

Rotating the Horn
The ULTRA-X40/42 may be rotated for increased installation flexibility. However, care must be taken so as to not damage the loudspeaker.
Note
In the paragraphs below, instructions and graphics for the ULTRA-X40 are used. The same procedure holds for the ULTRA-X42 (with 110° replaced by 70°).
Remove the grille by removing the four 10-32 x 1.00-inch flat-head Phillips screws (two on the top and two on the bottom) of the loudspeaker grille.
Remove ULTRA-X4x Grille Frame
Remove the four truss-head Phillips 10-32 x 3/4-inch screws holding the horn in place.
Removing Four Screws Holding the Horn in Place
Determine the present orientation of the horn by checking the horn throat orientation when the speaker is vertical with the port at the bottom. The cabinet is vertical when the Meyer Sound Logo on the horn and on the bezel are at the top.
If the present orientation is 110° horizontal by 50° vertical (horn throat is vertical, the horn may only be rotated in the clockwise direction.
Caution
Do not pull the horn out to rotate and do not use force. It should rotate smoothly if rotated in the correct direction. The rotation angle is NOT continuous. It is limited to 90° of travel between the two orientations where the Meyer Sound emboss on the bezel lines up with either the company logo or the engraved company name on the horn.
110° horizontal by 50° vertical horn orientation
Clockwise Rotation of Horn to achieve 50° horizontal by 110° vertical horn orientation -90° rotation direction
If the present orientation is 50° horizontal by 110° vertical horn throat is horizontal, the horn may only be rotated in the counter-clockwise direction.
110° horizontal by 50° vertical horn orientation
Counter-clockwise Rotation of Horn to achieve 110° horizontal by 50° vertical horn orientation
Replace the four screws removed in Step 2 to resecure the horn into position. Be sure to use the 10-32 x 3/4-inch screws. The recommended torque value for the horn screws is 19 in-lb (2.15 N·m).
Replace the grille and secure it with the four 10-32 x 1.00-inch screws removed in step 1. Meyer Sound recommends applying blue thread locker (medium strength) to screws in the leading three threads before replacing them. The recommended torque value for the grille screws is 8 in-lb (0.90 N·m).
Basic Eye Bolt Rigging
The ULTRA-X40 loudspeaker can be suspended simply using M8 eye bolts. A minimum of two eye bolts are required when suspending a single loudspeaker. The use of two eye bolts provides the added flexibility of aiming and tilting the loudspeaker for targeted coverage. Meyer Sound offers a kit with 2 black-coated M8 x 13 mm eye bolts (PN 40.287.057.01).
ULTRA-X40 with Two Eye Bolts
Note
Up to two ULTRA-X40 loudspeakers, oriented vertically, can be suspended with Meyer Sound eye bolts at a 5:1 safety factor. For this configuration, the top loudspeaker would have two eye bolts installed on its top and two eye bolts installed on its bottom (for connecting to the second loudspeaker), and the bottom of the upper loudspeaker requires the optional Thread Reducer M20 to M8 35MM accessory (PN 40.010.540.01).
Pole-mounting the ULTRA-X40
The MPK-POLE-35MM-M20 (PN 40.010.973.01) provides an easy and efficient way to mount the ULTRA-X40/42 on top of a 750-LFC (or 900-LFC). The MPK-POLE-35MM-M20 features all steel shafts that telescope from 36.5–60 inches and employs a secure knob to hold it in a specific position. The upper shaft includes the removable PAS-M20 Adapter Sleeve that fits the ULTRA-X40/42 internal 35 mm and M20 pole mount receptacle to make this connection more robust.
Meyer Sound offers the PAS-M20-35MM with M20 slug adapter sleeve separately (PN 40.010.974.01) for use with third-party 35 mm poles.
MPK-POLE-35MM-M20 kit
The MPK-POLE features a lift assist that provides approximately 40 lb of internal gas cylinder pneumatic lift. The lower end of the pole is 35 mm in diameter and has an M20 threaded lug for stability that can be removed if necessary. In addition, the MPK-POLE-35MM-M20 kit includes an adapter for converting the bottom diameter from 35 mm to 38 mm.
Locate the set screws on the Removable M20 Slug side of the pole.
Loosen the set screws using a 2.5 mm hex wrench. Do not loosen so far that the screws fall out of the pole and are lost.
Using Hex Wrench to Loosen M20 Slug Set Screws
Loosen the M20 lug by rotating counter-clockwise (inserting a screwdriver through the lug can help with this process) and remove it.
Inserting Screwdriver to Remove M20 Lug
Tighten the set screws enough to ensure they will remain in the pole.
Pole with M20 Slug Removed
The pole can be used without the lug for loudspeakers that have 35 mm cup mounts without M20 threads, or the 35 mm to 38 mm adapter may be slipped onto the bottom for loudspeakers that have 38 mm cups.
Pole with 35 mm to 38 mm Adapter Sleeve Attached
Meyer Sound recommends that a 750-LFC (or 900-LFC) be upgraded with the 35 mm/M20 internal pole mount cup (PN 40.271.016.02) for a more stable connection. This part is included with the MPK-POLE kit.
35 mm/M20 Internal Pole Mount Cup (PN 40.271.016.02)
The PAS-M20-35MM Adapter is designed to securely fit into the M20 thread of the ULTRA-X4x integral pole mount. The separate knob on the adapter tightens it to the pole. (It can also be secured onto any other standard 35 mm pole.)
Tip
Use the PAS-M20-35MM knob to secure the adapter to a pole when packing the pole for travel.
The PAS-M20-35MM may be independently (apart from the pole) threaded into the ULTRA-X4x, and then the loudspeaker/PAS-M20-35MM Adapter combination mounted onto a pole that is already secured in the subwoofer. The loudspeaker may be aimed horizontally, and the PAS-M20-35MM knob tightened.
Inserting the PAS-M20-35MM Adapter Independently
Settling Loudspeaker/Adapter Combination onto Pole
Alternatively, the PAS-M20-35MM Adapter can be secured to the pole first and then the two items jointly inserted into the subwoofer mounting cup and tightened. The loudspeaker may then be lifted onto the PAS-M-20-35MM adapter and rotated until the M20 thread is tightened within the loudspeaker’s mounting cup. Loosening the PAS-M20-35MM Adapter knob after the loudspeaker/ PAS-M20-35MM Adapter M8 connection is secure can again facilitate horizontal aiming of the loudspeaker.
Rotating Loudspeaker onto PAS-M20-35MM
Note
The ULTRA-X40/42 integral pole mount adapter will receive any 35mm pole shaft. However, the use of the Meyer Sound MPK-Pole-35MM-M20 and the PAS-M20-35MM is recommended to make a more robust connection.
When using a third-party pole, make sure the pole is designed to support the total weight of the ULTRA-X40/42 loudspeaker and observe all safety precautions specified by the pole manufacturer.
MYA-X40 Mounting Yoke
The MYA-X40 mounting yoke (PN 40.287.039.01) suspends a single ULTRA-X40/42 loudspeaker and supports a wide range of horizontal and vertical adjustments. The yoke attaches to the top of the loudspeaker using three of the six rig nuts. The kit includes three M8 bolts and three M8 knobs. The bolts are recommended for fixed installations. A hanging clamp and steel safety cable (not included) are required to suspend the MYA-X40 mounting yoke.

The MTC-X40 Top Channel kit (PN 40.287.130.01) includes a pinnable link in a channel that mounts directly to the ULTRA-X40/42 rig nuts or into an MCP plate. It supports pick-up of up to three ULTRA-X40/42 loudspeakers from a single point using the two included lock pins and 3/8-inch black shackle. The MTC-X40 Top Channel attaches to the speaker or to an MCP50-X40 or MCP70-X40 plate with two M8 bolts.
MTC-X40 Top Channel Kit Installed at Top of Cab
The versatile configuration of the channel and link, with the ability to slide the pinnable link within the channel, facilitates 9 different top pickup points. This flexibility allows for approximately +10° to –30° tilting of a loudspeaker that hangs from a single point.
MTC-X40 Pickup Points
Using multiple versions of this kit (together with the Thread Reducer M20 to M8 35MM part sold separately) allows the user to create two- and three-loudspeaker angled configurations.
Note
Using multiple MTC-X40 Top Channel Links in a multi-loudspeaker configuration requires the use of the Thread Reducer M20 to M8 35MM on the bottom of each loudspeaker to which an MTC-X40 will attach.
Attaching MTC-X40 to Bottom
In the example figure below, one Thread Reducer M20 to M8 35MM is required for the upper loudspeaker cabinet.
Example of two MTC-X40 Top Channels linking speakers at a 33° angle with a third MTC-X40 channel on top for pickup point.
Caution
A three-loudspeaker cluster using multiple MTC-X40 Top Channel Links requires the use of a pullback cable attached to an MTC-X40 Top Channel Link that is secured to the bottom of the lowest loudspeaker, as shown in the figure below.
Note
In the figure below, three Thread Reducer M20 to M8 35MM parts are required—one for each loudspeaker cabinet bottom.

MCP50-X40 and MCP70-X40 Cluster Plates
Meyer Sound offers two cluster plate versions: the MCP50-X40 Cluster Plate (PN 40.287.100.01), which when used in pairs, facilitates installation of up to three ULTRA-X40/42 loudspeakers in both horizontal and vertical clusters at variable splay angles between 10° and 50° in 5° increments, and the MCP70-X40 Cluster Plate (PN 40.287.400.01) that supports splay angles between 40° and 70°, also in 5° degree increments.
MCP70-X40 Cluster Plate (M8 knobs in transport positions)
MCP70-X40 Cluster Plate (M8 knobs in transport positions)
These kits include four M8 bolts and four M8 knobs. The bolts are recommended for fixed installations, while the knobs are for portable applications. The MCP plates include four threaded positions to hold the M8 knobs during transport.
Using these cluster plates, along with the MTC-X40 Top Channel, or the MTB-X40 Top Bracket (see MTB-X40 Top Bracket, users have the ability to create horizontal and vertical two and three-speaker clusters.
Even splay angles are obtained by using symmetric holes on either side; odd splay angles use a wider position hole on one side of the cluster plate. See Table 8 for examples.
Caution
When making horizontal clusters, always use two plates—one on top and one on bottom—to splay two adjacent loudspeakers (two plates for two-loudspeaker clusters, four plates for three-loudspeaker clusters).
Note
Optimal acoustical performance for an ULTRA-X40/42 array is achieved by using an adequate number of units as well as selecting the specific angles between cabinets to fill the requirements of the application. In general, larger angles can create a hole in the coverage and smaller angles can cause too much interaction.
Tip
The MAPP System Design Tool, covered in greater detail in Chapter 7, is the method of choice to enable you to make accurate and comprehensive predictions for optimal coverage during the design phase.

The table below provides illustrations of the type of splay angle configurations possible with two- and three-loudspeaker, horizontal and vertical configurations.
Tip
Use MAPP to accurately predict the interaction of loudspeakers at different angles to ensure appropriate loudspeaker deployment and subwoofer integration. For more information, see MAPP System Design Tool.

Caution
When mounting the MTB-X40 from the Center hole (Figure 69), a maximum of two loudspeakers maybe clustered.
When making three-loudspeaker vertical clusters using the MTB-X40, the MTB-X40 must always be horizontal (0°) with respect to the floor.
For three-loudspeaker clusters, there are BGV-C1 limitations on the maximum angles between the MTB-X40 and the first loudspeaker, and on the angles between the first/second and second/third loudspeakers. See Figure 69, Figure 70, Table 9 and Table 10.
