Drawing on proven expertise and the full know-how gained through the development and production of previous versions since the LD210, this latest generation LD230 "TDR" sets a new benchmark for excellence in covering the 20 Hz–200 Hz range. Thanks to its advanced technologies, this 23 cm woofer pushes the limits of what a loudspeaker of this size can achieve: delivering exceptional performance, whether used as an active subwoofer or as the low-frequency driver in ultra high-end speaker systems.
