Processed Active Subwoofer  1200W RMS – 137dB SPL

 QSA 118SA

Overview

The Q118SA is a newly designed, 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 100mm ventilated coil, it has negligible power compression, ensuring maximum acoustic pressure even after hours of continuous use.

The supplied 1200 watt 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.
