This paper describes the current performances of the ground based interferometric gravitational wave (GW) detectors in the low frequency region (from 10 Hz to 100 Hz). The detectors’ design sensitivity, where only fundamental noises contribute, is currently not achieved by any of them, which are instead limited by control noise. In the following, the current status of these detectors is described, together with the status of the research aimed to improve the low frequency limit in view of the next generation detectors.
