Hertz Mille PRO MPS 300 S4 12” Shallow Mount Subwoofer
The Hertz Mille PRO MPS 300 S4 is a premium 12” shallow mount subwoofer designed to deliver strong, controlled bass in vehicles where space is limited. With an ultra-shallow mounting depth of only 88 mm, this subwoofer is ideal for compact sealed enclosures, custom boot installs, under-seat style boxes and tight-space audio builds.
Built with a polypropylene cone, high-density flux ferrite magnet and a single 4 Ohm voice coil, the MPS 300 S4 provides deep low-frequency output while maintaining accuracy and control. Its 500W RMS power handling and 1000W peak rating make it suitable for serious daily audio systems where powerful bass is needed without taking up excessive space.
The MPS 300 S4 is optimised for compact sealed enclosures from around 22.7 litres, making it a great option for clean, space-saving installs while still delivering the strong low-end performance expected from the Hertz Mille PRO range.
