Signature Sound for Portable and Installation

The Martin Audio Blackline X12 compact passive loudspeaker delivers high sound levels - either as a stand-alone system or supplemented by a BlacklineX subwoofer to form a remarkably powerful sound reinforcement system, given its size and portability. Fitted with a screw-free steel grille, the X12 features comprehensive mounting options that include wall bracket, eyebolt suspension, and pole-mounting. With a 12" (300mm) LF driver unit and a 1" (25mm) exit compression driver on a rotatable horn, its 80° x 50° dispersion pattern is ideal for medium throw applications. The Martin Audio Blackline X12's enclosure is constructed from birch/poplar plywood and coated with black textured paint. The X12 passive loudspeaker may be used with or without a system controller. For demanding applications, Martin Audio recommends a DX0.5 system controller configured to perform EQ and limiter functions. The DX0.5 may also be used to configure systems for additional sub-bass cabinets (X12 + X115 or X118).


  • Compact passive two-way system
