MLK 165.3 Legend

The MLK 165.3 system pairs the ML 165.3 woofer and ML 28.3 tweeter with the dedicated MLCX 165.3 crossover.

The ML 165.3 woofer shares its core technologies with the ML 1650.3 Legend, including a Boundary Free Surround, a V-cone profile pressed-pulp cone with cotton fibres, and a six-spoke aluminium basket with vented holes. It uses a high-density ferrite magnet assembly, optimised for mid-frequency performance.

The ML 28.3 tweeter uses the same Neodymium magnet assembly as the ML 280.3 Legend and benefits from FEA-optimised dome profiling. It omits the more exotic features of the ML 280.3 — the die-cast aluminium faceplate, CNC-machined solid aluminium body and copper short-circuit ring — but retains the same core acoustic engineering.

The MLCX 165.3 crossover includes a Hi-Contour control to adjust the ML 28.3 tweeter's cut-off frequency, allowing the crossover point with the ML 165.3 woofer to be set according to speaker placement in the vehicle. A three-position tweeter level control with 2 dB step attenuation enables fine-tuning of timbre balance.
