Martin Audio - Backline Q15-B Enceinte passive 2 voies 15"

The Martin Audio Blackline Q15-B 2-way passive loudspeaker is a 15-inch PA speaker capable of handling high sound pressure levels. It features a 380mm bass driver with a 4" voice coil, which produces a solid, dynamic bass, useful for DJ sets, live bands or high-volume events. The 1.4" compression driver with 3" dome ensures accurate highs even when the system is pushed.

The differential-dispersion horn can be rotated to match the orientation of the loudspeaker, allowing coverage to be adapted to the front or back of the stage. Horizontal dispersion varies between 70° and 90°, allowing sound energy to be concentrated where it is needed, while maintaining good homogeneity. The vertical dispersion of 50° helps to limit losses and parasitic reflections in difficult rooms.

With a power handling of 800 W AES and peaks of 3200 W, this loudspeaker keeps up the pressure over long performances without crashing. It reaches 133 dB at peak, which corresponds to use in clubs, concerts or events where the volume needs to remain stable and impactful. Its frequency response goes down to 51 Hz, which already provides a decent base at low frequencies, although it comes into its own with a subwoofer for the most demanding applications.

The multi-angled plywood cabinet can be positioned in a variety of ways, notably as a discreet stage monitor. The structure incorporates a die-cast aluminium chassis that facilitates heat dissipation from the motor, ensuring better durability under heavy loads. The screw-mounted steel grille provides effective protection for components on tour. Numerous M8 inserts open the door to fixed or suspended mounting as required.

Integrated handles simplify handling, despite weighing just 33.8 kg. NL4 connectors enable fast, reliable cabling in a professional environment. This loudspeaker requires a suitable amplifier and processor to get the best out of it, particularly for filtering and equalisation. It is clearly aimed at contractors and technicians who want a loudspeaker capable of covering a stage or a track without compromising on impact and legibility.
