The Dynaudio Acoustics 9S True Bass Active Subwoofer utilizes a powerful Class-D amplifier to power the onboard 9.5 woofer and is well suited for any mixing or mastering project. The 9S outperforms its predecessor, the BM 9S II, by utilizing the long-throw driver, which ensures the accurate reproduction of frequencies from 22 Hz to 175 Hz and max SPL output of 106 dB.
The rear panel offers stereo satellite XLR inputs and outputs with a variable crossover (50 to 150 Hz), which ensures that the connected full-range speakers perform at their best. Additionally, there is an XLR LFE input and output, allowing the subwoofer to daisy-chain additional subwoofers. Whats more is there is a master/slave switch, which allows the control of the additional subwoofers to be set from the master, making for easy and simple adjustments. The Dynaudio Acoustics 9S True Bass subwoofer ships with a detachable baffle grille and a power cord.
