About the Q Acoustics Q SUB120 Subwoofer
The Q SUB range is a three-size family of active subwoofers (8, 10 and 12 inch) with digital signal processing for set-up, built to partner Q Acoustics speakers in stereo or home cinema. The Q SUB120 is the largest, made for big rooms and big speakers.
It reaches 28 Hz (-6 dB) with a 114 dB maximum output, enough for the low-frequency effects in a film soundtrack as well as a stereo system. It has more power than the older Q B12 subwoofer, and it is the subwoofer in the Concept 50 5.1 home cinema pack.
DSP adjusts the system gain to the source, and the phase, delay and low-pass controls let you tune the sub to your room.
