HERTZ MM 15.1 UNLIMITED SPL subwoofer motor 38cm 8000W

The Hertz MM 15.1 UNLIMITED is a 38 cm SPL subwoofer motor designed for high-level sound pressure competitions. It is built to reach maximum output when paired with the moving assemblies of the Hertz MG 15 series. With a peak power rating of 8000 W and a continuous RMS rating of 2000 W, it suits enthusiasts who want to push decibel levels in competition.

The large magnet system with high-permeability steel plates is designed to deliver a steady, low-distortion airflow even at extreme excursions. The basket and motor assembly are bonded with epoxy resin and damped, which the manufacturer states provides rigidity and reduced vibration. The diaphragm is said to remain accurately controlled up to 18.5 mm of excursion.

The motor is compatible with the diaphragms and voice coils of the MG 15 series, so builders can choose the moving assembly that best suits their setup and tune it precisely. At around 24.9 kg, it is a substantial component for demanding custom builds.
