In recent decades, new and better detectors for X-ray spectroscopy have been developed, many of them based on Silicon Drift Detectors (SDD). We present a further improvement resulting from the dedicated optimization of the whole detection system architecture. The novel system has been designed for Low Energy X-Ray Fluorescence (LEXRF) for the TwinMic beamline at Elettra Sincrotrone Trieste, where it was tested. It is composed of 4 trapezoidal monolithic SDD arrays, each having 8 square cells; the total non-collimated area is 1230 mm${}^{2}$ and the instrument is optimized to work in vacuum in a 200--4000 eV energy range.
