Grimm Audio released the original model of the low-frequency module SB1 , designed to work with shelving displays LS1 and give a very clear and powerful bass.
This is achieved through the use of the original Digital Motional Feedback (DMF) technology , the foundations of which were laid back in the 1970s by Philips engineers. The idea of controlling the displacement of the diffuser by introducing feedback has been radically improved by the use of the latest sensors and digital processing. As a result, the Grimm Audio SB1 is the smallest subwoofer on the market capable of linear operation from 20 Hz to 500 Hz.
The new version has a modified driver and a 700-watt amplifier , the Grimm Audio SB1 subwoofer can also be used with other active monitors, for which there is a special switch on the rear panel.
