HERTZ MP 250D4.3 Mille PRO dual voice coil woofer (4+4 Ohm)

The Hertz MP 250D4.3 Mille PRO is a car subwoofer with dual voice coils and a 4+4 ohm impedance, delivering high output in a compact design. It was built to bring the manufacturing know-how and material quality of the flagship Legend series to a wider audience.

Like the Legend range, its cone is made of mineral-enriched pressed paper. The V-cone profile adds stiffness so the cone moves like a piston. The surround is made of high-purity butyl rubber (IIR-butyl), which supports clean reproduction.

The lightweight die-cast aluminium basket matches the Legend series, providing mechanical damping and a clear, precise sound. A dedicated cooling system removes the need for a large rear vent. Snap-in terminals allow secure connection of 8 AWG speaker cable.
