FLE Series


  • The FLE-S18 is the universal subwoofer designed to match with FLE-12PT, FLED8PT line array, ACT coaxial and KR systems, lowering the combined system operating range down to 40Hz.

    FLE-S18 is a bass-reflex tuned enclosure. It is powered by a 18"LF transducer, which provides exceptional impact and high sensitivity, low thermal compression and reduced distortion. The special reflex structure allows the vents featuring a laminar airflow and reduced turbulence noise even at the very highest operating levels. Compared with GRF previous subwoofer system, FLE-S18 has a fashionable appearance, with the unique front grille, the SPL is able to increase 5dB.

    FLE-S18 subwoofer requests an additional amplification & DSP controller to enable perfect bass output. The DSP controller should has advanced crossover functions, system EQ, and dual thermal and over-excursion protection of the transducer.

    GRF‘s recommendation for FLE-S18 system match as follows:-
    The standard mode using FLE-S18 as a companion to FLE-12PT, FLE-D8PT, ACT-15M, ACT-12M and GRF KR series system, the FLE-S18‘s preset is high-pass filter at 80 Hz .

    The performance of the FLE-S18 depends on the choice of preset and physical system configuration. The cabinet is made of high grade  birch plywood and features an integrated flying accessory.
