When installing Meyer Sound loudspeakers, always observe the following precautions:
Use all Meyer Sound products in accordance with local, state, federal, and industry regulations. Owners and users must evaluate the reliability of any rigging or mounting method for their application. Rigging loudspeakers requires trained and experienced professionals.
Use mounting and rigging hardware rated to meet or exceed the suspended weight.
Make sure to attach mounting hardware to the building's structural components (studs or joists), and not just to the wall surface. Verify that the building's structure and the anchors used for the installation will safely support the total weight of the mounted loudspeakers.
Use mounting hardware appropriate for the installation surface.
Tighten bolts securely. Meyer Sound recommends using Loctite® on bolt threads and safety cables.
Inspect mounting and rigging hardware regularly. Immediately replace any worn or damaged components.
Assembly instructions
Two cluster plates are included in each kit. One kit connects two ULTRA-X80 series loudspeakers. Secure each plate with the provided fasteners. When using the screws to secure a plate, flip the plate so the countersunk holes are facing out. When using the knurled knobs to secure a plate, flip the plate so the straight-bore holes are facing out.


For two and three-wide horizontal portrait arrays, each of the top cluster plates must be connected to a structural attachment point either via a MRB-T1 Rigging Bar, two MHR-T1 Hoist Rings.

Suspend two-loudspeaker vertical landscape arrays with four MHR-T1 Hoist Rings secured to the four M8 loudspeaker rigging points, as shown below. For three-loudspeaker vertical arrays, mount four hoist rings to the array plate, as shown below. The MUB-T1 U-bracket is rated to suspend only one ULTRA-X80 series loudspeaker and is not suitable for vertical landscape arrays.

Four mounting holes along the center line of each plate accept M8 × 1.25 fasteners. Plate thickness: 0.37 in (10 mm).
The cluster plate mounting hole determines the splay angle: 25°, 32°, 40°, 50°, 60°, 70°, or 80°.

Below, the splay angles, adjacent horn sides, and corresponding fill loudspeaker level reductions are listed. ULTRA-X80 loudspeakers use a rotatable 95° × 40° horn; ULTRA-X82 loudspeakers use a rotatable 50° × 40° horn.
25° splay, 40° horn sides, 4 dB offset
32° splay, 40° horn sides, 2dB offset
40° splay, 40° horn sides, ULTRA-X80 or ULTRA-X82, no offset
50° splay, 50° horn sides, ULTRA-X82, no offset
60° splay, 95° horn sides, ULTRA-X80, 4dB offset
70° splay, 95° horn sides, ULTRA-X80, 2dB offset
80° splay, 95° horn sides, ULTRA-X80, 1dB offset
