SMX 12

One key to a good performance is a good monitor!

The SMX 12 is a compact, extremely versatile 2-way passive coaxial monitor in bass reflex design. Thanks to the built-in 12″-LF with powerful 3″ voice coil and a 1″-HF with 1.7″ voice coil, the SMX 12 monitor is powerful and assertive in any mix and has a harmonious, neutral sound character. This allows any musician to hear themselves better and bring out every nuance of their performance. The clearly audible signal in the 80° x 80° coverage angle is easy on any singer’s voice – the more precise they hear themselves, the less effort is required for their performance. At the same time, the SMX 12 monitor remains uncomplicated and feedback-proof.

With a power handling of 1,600 W (peak) and 136 dB max. SPL (peak), the SMX 12 boasts an impressive stage presence, yet keeps distortion at an extremely low level over the entire frequency range from 60 Hz to 20 kHz. The high sensitivity of 99 dB enables smooth, powerful reproduction throughout the entire dynamic range.

SMX 12 monitors can also be used in combination with subwoofers such as the S 15 PRO for small to medium-sized events, or for fixed installations. The elegant hidden cable management and connector panel ensures a neat and tidy appearance on stage or in any other application. Equipped with M10 fly points and accessories like the SMX 12 UB U-bracket, SMX 12 can be utilized for applications where the speaker needs to be mounted to a wall, ceiling, truss or speaker stand. The optional padded cover SMX 12 TC protects the monitor during transport and storage.


12" High Efficiency Woofer

SMX 12 is a compact yet powerful tool for various monitoring requirements on and off stage.

3 handles for easy handling in all situations

By skilfully attaching the 3 safe handles, the system can be easily transported in any situation.

Recessed connector panel

Due to the recessed I/O panel of the monitoring system, no connectors are visible to the viewer.

Maximum Versatility

SMX 12 and SMX 12A are excellent stage monitors – and much more. The extensive accessories allow for a large number of different applications besides classic monitoring. The centrepiece is the SMX 12 UB mounting frame – it allows the SMX 12 and SMX 12A to be tilted steplessly, for example, for wall mounting. With the SPS20 mounting pole, the SMX monitors can be mounted on a subwoofer in a flash and thus become an ultra-portable PA system or a quickly set-up side fill. Rigging is also possible with the SMX 12 or SMX 12A flown as front fill, for example. In short, using the speakers of the SMX series exclusively as monitors is an excellent choice – but almost a waste.
