SMX 12A

One key to a great performance is a good monitor!

SMX 12 and SMX 12A are outstanding stage monitors—and so much more. The extensive range of accessories enables a wide variety of applications beyond classic monitoring. The core component is the SMX 12 UB, which allows the SMX 12 and SMX 12A to be tilted steplessly, making wall mounting, for example, possible. With the SPS20 mounting pole, the SMX monitors can be quickly mounted on a subwoofer, transforming them into an ultra-portable PA system or a rapidly deployed side fill. Rigging is also possible, allowing the SMX 12 or SMX 12A to be flown as front fills, for instance.
In short, using the SMX series speakers solely as monitors is certainly an excellent choice—but almost a waste of their potential.

Feature 1
12" high-efficiency woofer: With its 12″ woofer, the SMX 12A is a compact yet powerful tool for a wide range of monitoring applications both on and off stage.
Feature 2
8 well-designed DSP factory presets: Gain and preset selector with 8 pre-defined application settings expand the range of possible uses.
Feature 3
Recessed connection panel: Thanks to the recessed I/O panel of the monitor system, no connectors are visible to the audience.

The SMX 12A is a compact, extremely versatile 2-way coaxial monitor in a bass reflex design. Thanks to the built-in 12″ woofer with a powerful 3″ voice coil and a 1″ tweeter with a 1.7″ voice coil, the SMX 12A delivers punchy, assertive sound in any mix and impresses with a harmonious, neutral sound character. This allows performers to hear themselves better and bring out every nuance of their performance. The clearly audible signal, with an 80° x 80° dispersion angle, also helps to protect the voice—the better you can hear yourself, the less strain is needed when singing. The SMX 12A monitor remains straightforward and resistant to feedback in any situation.
The SMX 12A features a 2-channel Class-D amplifier with a total output of 484 W (LF: 416 W @ 6.5 Ω, HF: 68 W @ 14 Ω). No external device is needed—the internal amplifier is perfectly matched to the loudspeakers and offers eight DSP factory presets to make setup as quick and easy as possible.
SMX 12A monitors can also be used in combination with subwoofers such as the S 15 PRO for small to medium-sized events or for permanent installations. The elegant, concealed cable management and connection panel ensure a tidy and clean appearance on stage or in any other application. Equipped with M10 flying points and accessories such as the SMX 12 UB bracket, the SMX 12A can be used in applications where the loudspeaker needs to be mounted on a wall, ceiling, truss or speaker stand. The optional padded cover SMX 12TC protects the monitor during transport and storage.
