Three-Way Bi-Amp Trapezoid Hybrid® Fully Horn Loaded

Where to Buy or Rent

The new FH3 is a very high performance, all-horn, three-way system in a single, horizontally formatted, wide-bandwidth package aesthetically designed to complement the Blackline3 collection.

  • ‘Phase-ball’ loaded mid-driver
  • Hybrid® LF section
  • Fitted with handles and castors
  • Horizontal format for low profile installs


  • Larger club performance
  • Large scale installs

High quality and unique drivers deliver exceptional performance in all bands. The Hybrid® low frequency section comprises a horn-loaded 15” (380mm)/4” (100mm) voice coil ultra-long-excursion neodymium magnet driver that is also reflex loaded to extend the LF output to below the natural cut-off point of the horn. The LF driver features a water resistant cone and triple roll surround for increased excursion.

The mid-horn of the FH3 has a unique ‘phase-ball’ loading device which maintains the constant directivity characteristics of the horn at the upper end of its range. It is driven by a 10” (250mm) midrange driver with an aluminium demodulating ring for improved high-mid clarity and reduced distortion when driven hard. The 70° x 40° HF section of the FH3 features a neodymium 1” (25mm) exit compression driver with a polyamide diaphragm for high sensitivity and extended HF performance. The internal mid/high passive crossover allows this three-way system to be driven in a bi-amp configuration.

A Martin Audio DX0.5 and DX4.0 Electronic Controller are available to provide FH3 crossover and limiter facilities.
