UNPACKING AND INSPECTION

The Community M12 loudspeaker is inherently rugged and packed in well-designed shipping cartons. It is

recommended that you carefully inspect the unit after removing it from the packaging to check for any

hidden damage due to possible shipping incidents.

CAUTION: When unpacking and handling an M12 be careful not to scratch or scrape the

black paint on the perforated metal grille. The finish on the grille protects the steel from

corrosion, and any scratches or scrapes that remove the finish leave the steel exposed to

corrosion.

Please note that once the shipment has left Community (or the dealer) the responsibility for damage is

borne by the freight company. If there is damage, you must file a claim directly with the freight company.

Each carrier has its own set of rules and regulations, with their own unique forms to fill out.

You are responsible for contacting the freight company immediately if you discover shipping damage. Save

the carton with all shipping materials in the event you need to ship the unit in order to avoid damage

claims being denied due to the lack of proper packaging. The Community dealer and the factory will try to

help in any way possible, however, please remember it is up to the party receiving the shipment to file the

claim.

The shipment is packed with the following:

(1) M12 loudspeaker

(1) Owner’s manual

(1) Warranty card

INTRODUCTION

The Community M12 is a two-way, full-range, bass-ported performance loudspeaker. Its low profile exterior

occupies a very small footprint, making it an ideal choice for stage monitors. The rugged multilayer glass

composite construction, stainless steel grille and an abrasion-resistant non-reflective finish make the M12 an

excellent choice for high ambient light scenarios, such as TV broadcasts and live stage events. Specially

molded channels and cable clips allow speaker cables to be routed through the sides and the bottom of the

enclosure, and the dual Neutrik NL4 connectors are tucked safely away in a pocket beneath the enclosure.

The M12 features a high-powered 12-inch woofer and a 2-inch exit wide-band high frequency driver, which

are mounted to a molded one-piece asymmetrical horn with a 90-degree dispersal pattern at the top and

40-degree dispersal pattern at the bottom. This unique horn design allows the M12 to operate at full-range

output and be equally effective up close or at a distance. The M12 can be ordered with the HF horn

mounted either to the left or right of the woofer, allowing for mirrored pairs.

The M12 offers numerous features and advances in technology. Some of these include:

•Low profile design, high style exterior with small footprint

•Unique asymmetrical 40° – 90° x 70° coverage pattern

•Multilayer glass composite construction

•Ergonomic rubber pocket grip handles

•Non-reflective exterior with matching heavy-duty non-reflective grille

•High powered, 12-inch woofer

•2-inch exit wide-band compression driver on an asymmetrical horn

•Switchable bi-amp/passive configuration with well protected dual NL4 connectors

•Available in black or white finishes, with mirror right or left horn configurations

•Optional installation models available with M10 hang points and wall/ceiling mounting plate included

•Five-year warranty

NOTE: The high frequency driver is mounted to a molded one-piece asymmetrical horn

with a 90-degree pattern at the top and 40 degree at the bottom, allowing full-range monitor

output close up or at a distance, as depicted in Figure 2.

Figure 2: M12 dispersion pattern

The M12 is designed primarily as a performance monitor placed on the stage. Its low profile design makes

it suitable for a wide range of stage monitoring situations, including music concerts, TV broadcasts and live

theater events. Ergonomic rubber pocket grip handles on the portable model makes the M12 easy to lift

and easy to transport. In addition to traditional stage monitoring, the M12 may also be permanently

installed on a wall or ceiling and/or used as part of a main FOH (front-of-house) sound system in houses of

worship, conference centers, auditoria, lecture halls, and mounted under balconies for theaters.

PERFORMANCE MONITORING

Place the M12 on a flat surface. For full-range operation, connect the M12 to one channel of a power

amplifier (600W-900W per channel @ 8 ohms), using an appropriate cable wired with a Neutrik NL4

connector. Ensure that the switch on the underside of the M12 labeled “Bi-amp/Passive” is placed in the

“Passive” position. For bi-amp operation, one Neutrik Speakon input receives the HF output from an

appropriate power amplifier (130W/160W @ 8 ohms) and one Neutrik Speakon input receives the LF input

from an appropriate power amplifier (600W/900W per channel @ 8 ohms). In bi-amp mode, in order to

prevent possible damage to the HF element, an electronic crossover, analog or digital, must be used ahead

of the power amplifier channels. Set the electronic crossover frequency to 1.5 kHz to match the built-in

crossover provided for passive operation. Ensure that the switch on the underside of the M12 labeled “Bi-

amp/Passive” is placed in the “Bi-amp” position. For both passive and bi-amp operation, turn each

amplifier channel up to a comfortable listening level.

CAUTION: Operating the M12 at an excessive volume level can cause hearing damage

and/or permanent hearing loss.

Figures 6 and 7 depict the optional left and right HF configurations of the M12. This configuration choice

allows the M12 to be placed virtually anywhere around the performer.

Figure 6: M12R with the HF horn molded to the right of the LF driver

Figure 7: M12L with the HF horn molded to the left of the LF driver

The M12 is provided with cable channels on the back and side of the loudspeaker, along with clips located

on the bottom of the loudspeaker to neatly hold speaker cables, providing a safe and secure cable route to

the locking Neutrik NL4 connectors. This combination of routing and clips allows the loudspeaker to rest

flat on the floor for a lower profile on stage.

Community M12 – Installation / Operation Manual - Page 9

Figure 8: M12 Cable Clips

The M12 loudspeaker can be configured in multiples running from the same amplifier channel. When

connecting multiple M12’s to the same amplifier channel, connect the first M12 directly from the amplifier,

using 2-conductor, rubber-jacketed loudspeaker cable, with a Neutrik NL4 connector. Each M12 has two

(2) NL4 jacks. Connect the second M12 to the first by “daisy-chaining” it to the first M12. Since the M12 is

a nominal 8-ohm loudspeaker, connecting two (2) in this way creates a 4-ohm load across the amplifier, as

shown in the top part of Figure 9. If desired, a third M12 can be added the same way, as shown in the

lower part of Figure 9. For best results, use either 14 AWG or 12 AWG loudspeaker cable.

Figure 9: Multiple M12's running from the same amplifier channel

CAUTION: Adding a third M12, as shown in Figure 9, will create a 2-ohm load on the

amplifier. Please refer to the owner’s manual of the amplifier before connecting a third

M12 to ensure that the amplifier will support 2-ohm operation.

Community M12 – Installation / Operation Manual - Page 10

PERMANENT INSTALLATION

The install version of the M12 can be used anywhere a conventional 12-inch two-way loudspeaker would be

used. It can also be used in many applications where a conventional loudspeaker would not be appropriate,

such as overhead or under-balcony in a theater, conference rooms and distributed systems. The M12

install version is provided with a mounting bracket plate and four M10 hanging points. Connect the

mounting bracket to the M12 using the four provided 40mm hex bolts, 10mm lock washers and 10mm flat

washers. The entire assembly can then be mounted to a flat surface. The OmniMount bolt pattern on the

back of the bracket is drilled out at the center of gravity for safe and secure mounting.

Figure 10: M12 wall/ceiling mounting plate

Note: (1) OmniMount 120 bolt pattern is located at the center of gravity.

No hardware is provided to attach the M12 and bracket assembly to the mounting surface. Such hardware

must be supplied by the installer and should be sized and rated for the weight load of the enclosure. The

installer is solely responsible for determining if all rigging components that are used to mount or suspend

the enclosure are adequately sized and rated, and if the structure they are mounted or suspended from is

capable of safely supporting the aggregate weight load. It is always the installer’s responsibility to insure

that the combined weight load does not exceed the Working Load Limit of any one rigging fitting.
