About the Hertz MP 300 D2.3
The evolution of technology
The evolution of technology
When Hertz developed the Mille Legend Series, they utilized advanced design and high-quality construction to give you award-winning performance. Now the Mille Pro Series brings you the technological advancements of the Legend Series at a friendlier price point. Their MP 300 D2.3 12" subwoofer handles high-output levels to help you build a system with truly huge bass, and it's designed for smaller enclosures so you get more installation options.
Designed for high fidelity
The MP 300 D2.3 features the technically advanced V-cone®, which keeps its shape even at high volume levels to minimize distortion. The pressed pulp of the cone is combined with mineral powders for additional rigidity, while the rubber surround keeps things under control. The sub's aluminum alloy frame is designed to minimize resonance so it'll produce rich, clear bass while handling tremendous amounts of power. With 600 watts of continuous power handling (1200 watts peak), the MP 300 D2.3 will produce enough low end to satisfy even the most demanding listener.
Big sound, small enclosure
This sub is designed for use in compact sealed enclosures so you'll get maximum bass from your space. You can even mount the sub directly to the back wall of the enclosure using the included rubber damping disc, allowing you to use even smaller enclosures. The sub's dual 2-ohm voice coils help you draw maximum power from your amplifier.

Product Research
Features
Dual 2Ω Voice Coils: This woofer features two 2Ω voice coils to offer wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When the voice coils are wired in series, the woofer presents a 4Ω load.
Terminals: The spring post terminals will accept pin connectors, single banana plugs (but not dual), and bare wire up to 8 gauge.
Boundary Free Surround: This technology provides more cone surface area than other speakers of the same size, enabling it to move more air. The surrounds are made of butyl rubber, ensuring thermal and mechanical linearity.
Sealed Box: Hertz recommends a sealed enclosure volume of 28 liters (0.99 ft³). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.
Ported Box: Hertz recommends a ported enclosure volume of 36 liters (1.27 ft³) with one 352mm (13.86") x 45mm (1.77") x 700mm (27.56) long port. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.
Crossover: When using a sealed enclosure, Hertz recommends the low pass crossover point be 70 Hz - 80 Hz and a subsonic filter at 15 Hz. With a ported enclosure, the crossover point is lowered to 60 Hz - 70 Hz and the subsonic filter raised to 20 Hz. A 24 dB/octave slope is recommended for all crossovers.
