One key to a good performance is a good monitor!

The active SMX 12A is a compact, extremely versatile 2-way coaxial monitor in bass reflex design. Thanks to the built-in 12″ LF with powerful 3″ voice coil and a 1″ HF with a 1.7″ voice coil, the SMX 12A monitor is powerful and assertive in any mix and feature 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 12A monitor remains uncomplicated and feedback-proof.

The SMX 12A boasts a 2-channel Class-D amplifier with a total power of 484 W (LF: 416 W @ 6.5 Ω, HF: 68 W @ 14 Ω) on board. So there is no need for an external device – the internal amp is optimally matched to the speakers and brings eight DSP presets to make the set-up as short and simple as possible.

SMX 12A 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 recessed I/O 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 12A 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.

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 SMX 12A 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.
