WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice strongly recommends that the Sx/Sb-Series enclosures be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure the loudspeaker is safely installed and in compliance with all regulations. If the loudspeaker is suspended, Electro-Voice strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately.

The Mb Kits

Electro-Voice® manufactures three accessories to make the suspension of Sx/Sb-Series enclosures safe, easy and cost-effective: the Mb100 Eyebolt Attachment Kit, the Mb200 Installation Kit and the Mb300 Horizontal Array Kit. This instruction sheet gives a brief overview of how each of these suspension kits could be used so the correct kit can be selected. In addition, each of the suspension kits includes a separate instruction sheet with complete dimensions and full details for use.

Suspending Sx/Sb-Series Enclosures

The molded enclosures used in Sx/Sb-Series are lightweight and structurally sound. Each enclosure has four metric M8 x 1.25 metal inserts molded into the enclosure to aid in suspension and aiming. A single insert, correctly used, will safely suspend the weight of one enclosure with a safety factor in excess of 5 to 1. It will not support additional weight with a sufficient safety factor for overhead lifting. If multiple Sx/Sb-Series enclosures are suspended, Mb200 Installation Kits must be used to support and aim each enclosure.

Mb100 Eyebolt Attachment Kit

The Mb100 Eyebolt Attachment Kit is intended for very simple installations only, to suspend an individual Sx/Sb-Series loudspeaker in a near-vertical orientation (see Figure 1). A second, redundant insert point is provided in the top of the enclosure so a supplementary independent means of suspension can be attached when regulations specify. The enclosure can be positioned to angle downward slightly through the use of the pull-up point at the back of the enclosure.

Note that two top suspension cables should be used at all times to provide needed stability to the installation (see Figure 1).

Do not suspend Sx/Sb-Series enclosures face down from the ceiling using the Mb100 Eyebolt Attachment Kit. The M8 eyebolts are not rated for lifting loads at 90°, and such a configuration makes stabilization of the enclosure difficult. Instead, use the Mb200 Installation Kit for this and most other situations (see the Mb200 Installation Kit section).

Mb200 Installation Kit

The Mb200 Installation Kit provides a cost-effective and safe means of attaching Sx/Sb-Series loudspeakers to walls or suspending them overhead (see Figure 2). The kit contains a large, reinforced-steel bracket with a selection of thru-holes which allow the bracket to be mounted to different surfaces in a range of orientations. This kit is recommended for most installations, and is essential when arraying Sx/Sb-Series loudspeakers.

The Mb200 U-bracket extends from top to bottom of the Sx/Sb-Series loudspeaker and attaches at both ends. This securely “captures” the enclosure, allowing further loudspeaker systems to be added without increasing the stress on the first enclosure. It also allows the loudspeaker to be aimed in the desired direction and locked in place. For even greater flexibility, three-hole-pattern groups compatible with the OmniMount® 60.0 (originally Series 100) ^1 support system have also been incorporated into the Mb200 Installation Kit’s U-bracket (see Figure 2B, reference A).

Vertical arrays can be constructed by "daisy chaining" Mb200's together (see Figure 3). To achieve a slight downward angle, attach an additional cable to the lower Mb200 and use this cable to pull up the array, securing the cable at the desired angle and position.

No more than two enclosures should be suspended in a vertical array in this manner. If a taller array is required, you should provide a means of independent suspension for the remaining enclosures.

Again, note the use of two top suspension cables (see Figure 3) which provide stability and should be used at all times.

NOTE: The Mb200 mounting brackets will not work with powered (amplified) versions of the Sx/Sb-Series. Flush-mounted input panels (as opposed to recessed input panels on passive versions) cause the U-bracket to interfere with cables connected to the rear of the loudspeaker.

Mb300 Horizontal Array Kit

The Mb300 Horizontal Array Kit must be used in conjunction with the Mb200 Installation Kit. Select the required number of kits from the chart below:

Horizontal Array
Number of Enclosures in Array:	Number of Kits Required
	Mb200 Mb300
2 2 1
3 3 2
4 4 3
5 5 4
6 (Complete Circle)	6	6

Each Mb300 Horizontal Array Kit consists of two connector brackets (one top, one bottom) plus the hardware required to join these brackets to the U-brackets from two Mb200 Installation Kits. This combination of one Mb300 Horizontal Array Kit plus two Mb200 Installation Kits forms a solid frame suitable for suspending two Sx/Sb-Series loudspeakers in a horizontal array (see Figure 4). Holes are provided in the Mb300 brackets for attaching cables for suspension.

Two mounting angles, 50^ and 60^ , are possible using the Mb300 Horizontal Array Kit. Use of the 50^ angle results in a tight array with speaker sides touching (see Figure 5); use of the wider orientation results in improved coverage for multiple loudspeakers and allows construction of a complete, 360^ array (see Figure 6 for diagram of one half of a 360^ array). A vertical array can also be constructed using the Mb300 Horizontal Array Kit, but relatively few aiming angles are available.
