SMX 12

The SMX 12 is a real multi-purpose passive unit. It is a compact yet powerful tool for various monitoring requirements on and off stage. The high sensitivity and power handling provides ample headroom for equalization according to personal preference.

The M10 fly points and the additional mounting accessories increase its application range even further. Using the additional SMX 12UB U-bracket enables the SMX 12 to be mounted to a wall, the ceiling, a truss or a speaker stand. Additional mounting hardware allows safe per-manent or non-permanent installation. The optional padded cover SMX 12TC protects the product during transport and storage.
