CM 12a is a uniquely compact, self-powered 2-way coaxial stage monitor, with the flexibility to serve as a full-range PA speaker, making it a popular choice for live events, touring, DJ sets, drum fills, and front fills.

The horn orientation can be changed quickly by hand, with no tools needed. Created to deliver outstanding SPL for its size, CM 12a’s low profile design won’t get in the way of the performance.

The HF driver diaphragm assembly employs a high specification cotton composite dome together with a phasing plug, giving CM 12a its exceptional linearity, precision, and musicality.

An advanced AUDIOFOCUS Class D amplifier module with integral DSP offers easy and smart presets for both monitor and FOH configuration.

Housed in a rugged, road-ready enclosure with a rigid magnetic grill, CM 12a is built with pride in Belgium and coated in tough, weather-resistant polyurea to protect your investment.
