Active subwoofer. The Q118SA is extremely powerful subwoofer, capable of delivering extremely high SPL and guaranteeing significant low frequency extension. The optimisation of the woofer load volume and port tube with BEM finite element simulation, and the careful development of the grille and the protective fabric to minimise acoustic impedance, has led to a net improvement in performances as compared with previous models. Equipped with an high excursion ceramic B&C woofer with 100 mm ventilated coil, it has negligible power compression, ensuring maximum acoustic pressure even after hours of continuous use. The supplied 1200 W rms class D amplifier with switching power is equipped with a digital signal processor with entirely new algorithms. Equipped with 6 presets, each of which is not only associated with a different equalisation – to tailor the subwoofer response to various usage conditions – but also with different dynamic processor calibration to extend the maximum acoustic pressure to very high levels, with no deterioration of the original signal. This ensures absolute configurability of the sound obtained, great flexibility of use and above all an impressive SPL/size ratio. The 18mm birch plywood cabinet is equipped with 4 aluminium handles and two M20 stand supports, suitable for use on either the short or the long side. It is compatible with MITUS 206 and MUSE 210 systems in ground-stacked configuration, and is designed to allow 4 optional 100mm wheels to be fitted. An exceptionally powerful and versatile subwoofer that can be combined with a wide range of FBT speakers. Frequency response: 30Hz - 100Hz -6dB. Input impedance: 22 Kohm. Input connector: XLR with loop. Dimension: 550 x 700 x 720 mm. Colour: Black
