FPXFor 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.

The FPX 1.1000 only measures 1111⁄16 x 513⁄64 x 23⁄32″ (29.7 x 13.2 x 5.3 cm).


Very compact and easy to integrate, the FPX 1.1000 amplifier has been specifically developed for powering all types of subwoofer. It is stable at 4 Ohms, 2 Ohms and 1 Ohm, delivering a respective power of 420, 700 and 1000 Watts RMS. Whether it’s for an audiophile bass system or a powerful subwoofer, the FPX 1.1000 will meet all your needs.

It features all the settings you’d expect to find in such an efficient bass amplification system: adjustable low-pass active crossover with a slope of 24 dB, subsonic filter with a slope of 24 dB, bass boost and phase control.

The FPX 1.1000 comes supplied with a remote control for controlling the bass from the dashboard, and a pair of output lines for hooking up a second amp. This is especially useful for setting up a bass channel with two subwoofers and two amplifiers.
