Martin Audio - THH Enceinte Trapézoïde Hybride Horizontale

The Martin Audio THH is a fully horn-loaded 3-way loudspeaker designed for systems where acoustic pressure and projection are priorities. It is aimed directly at large club installations or demanding fixed configurations. Its horizontal format makes it easy to integrate into specific setups, particularly in stacks or on adapted stands.

The bass section is based on a 38cm driver with a 10cm voice coil mounted in a horn, with bass-reflex reinforcement to extend the bass response. This principle preserves the impact and dynamics of the horn while extending the frequency response downwards. The treated cone and reinforced suspension mean you can work at high levels without losing control.

In the midrange, a 25 cm driver takes over with a special 'phase-ball' device. This system maintains a constant directivity in the upper midrange, improving signal clarity, especially on vocals and percussive elements. The aluminium demodulation ring limits distortion when the system is pushed.

The treble section uses a compression driver with a 2.5 cm output mounted on a constant directivity horn. Dispersion of 70° horizontally and 40° vertically ensures controlled coverage, even in complex environments. The Kapton diaphragm withstands high levels while maintaining good definition.

The system works in bi-amplification, with active separation at 200 Hz and internal passive filtering at 2 kHz between midrange and treble. This configuration optimises the behaviour of each channel while simplifying the cabling on the operating side. Combined with a suitable amplifier and processor, the loudspeaker delivers high levels with good stability.

The 250-litre birch-multiply cabinet withstands the rigours of intensive use. The 12 M10 inserts facilitate mounting options, while the integrated handles and castors make it easy to move the unit around despite its weight of 77.5 kg. This format remains typical of performance-oriented systems.

In the field, this loudspeaker can be used as a main PA in clubs, as a powerful stack or as a fixed installation. It can be used on its own or integrated into a larger system as required. Its behaviour remains consistent when it comes to projecting far and accurately.

If you're looking for a loudspeaker capable of delivering a high level with controlled directivity and true horn behaviour, this model is clearly for use with a focus on performance and acoustic pressure.
