The FPX 1.1000 is a compact mono amplifier specifically designed for powering a subwoofer. Equipped with a complete range of settings for adjusting low-frequency sensitivity, a remote control and output lines, this amplifier can make all the difference. Whether it’s for powering an audiophiles bass system or a powerful subwoofer, the FPX 1.1000 will meet all your needs for your bass channel.


  • Mono Class D amplifier
  • Complete range of settings (active crossover, subsonic filter, bass boost, phase control)
  • Stable under 2 Ohms and 1 Ohm
  • Output lines
  • The FPX 1.1000 only measures 1111⁄16 x 513⁄64 x 23⁄32″ (29.7 x 13.2 x 5.3 cm).
  • 420 Watts RMS at 4 Ohms


For an amplifier to provide high power and musicality, efficiency and heat dissipation are two essential aspects.

In order to optimise these two key aspects, FPX amplifiers have been given a thick aluminium chassis (3/8″ / 9.5 mm for the top, 11/16″ / 17.5 mm for the sides).

The distribution of the components on the motherboard was also carefully researched to optimise the cooling capacity of the chassis.

The careful selection of each Class D component (switching power supply, oversized toroidal transformers and high-quality capacitors) has made it possible to create powerful but compact amps with excellent musicality


  • A powerful and ultra-compact amplifier
  • Perfect for audiophile installations or powerful subwoofer systems
  • Optimised heat dissipation
  • Extremely versatile
  • Remarkable power/performance/price ratio
