Description

The Sub At A Glance:

  • Ultra-shallow design: An 89 mm mounting depth makes the MPS300S4 ideal for installations where enclosure height is limited.
  • Compact enclosure flexibility: Optimized for sealed enclosures from 20 to 24 liters, or 0.7 to 0.8 cubic feet.
  • Strong power handling: Handles 500 Watts RMS and 1000 Watts Max.
  • Six-layer voice coil: The 38 mm copper voice coil provides high thermal capacity with a 4 Ohm impedance.
  • Extended excursion: A dedicated spider and coil support structure delivers 20 percent more cone excursion than traditional designs.
  • Controlled airflow: Air Intercooling Revolution technology helps prevent limitations caused by air compression.
  • Durable construction: A die-cast aluminum frame, solid 8 AWG spring-loaded terminals, and included screw-less mesh grille support a tough, installation-ready design.
  • Space-saving rear profile: The non-vented rear design helps reduce the enclosure depth required for installation.

The Hertz MPS300S4 brings deep rumble and solid low-frequency impact to vehicles where a conventional subwoofer box simply will not fit. Its shallow profile and high excursion capability let the bass reach into the cabin with convincing weight, making kick drums feel more immediate and low notes more physical without demanding a large enclosure.
