Hertz Mille Pro MPS 250 S4 Sub 10" 25cm Shallow Car Subwoofer 4 Ohm 500w RMS
MPS 250 S4 4 Ohm Single Voice Coil
Mille PRO shallow subwoofers have been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.
Extreme dynamics, unlimited power handling, realistic sound stage
Mille PRO Shallow Subwoofer
MPS 250 S4 is optimized to work in ultra-compact sealed boxes starting from only 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space - and the height - are limited.
Mille PRO subwoofer have a depth/performance ratio never achieved before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.
This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for spider and coil. This solution has allowed to move the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.
500 W continuous power handling is an incredible result for such a compact subwoofer. To accomplish this ambitious goal, the Hertz R&D has developed the proprietary AIR (Air Intercooling Revolution) technology, optimizing the fluid dynamics of the inner acoustic structure and the magnetic group to minimize the internal compression of air and maximize cooling capacity. The 6 layers, 1.5 in. (38 mm) voice-coil with cooling openings on the former contributes to the thermal stability of the subwoofer, making MPS subs ready to face to most demanding high-spl listening session.
The design of the magnetic unit has been FEM simulated to maximize force factor (BxL) symmetry and thus obtain an optimal linearity even at high excursions, perfectly controlling the inductance modulation.
Pole piece geometry has been optimized using a breakthrough simulation model that allowed improving unit force factor.
Hertz R&D also focused on modeling the cone/enclosure behavior: inside a sealed box, air behaves like a spring - a non-linear suspension - whose effect must be compensated to obtain a system as linear as possible at high excursions.

About Us
We've been doing this car audio thing for over 30 years for one primary reason... Passion. We got bit by the car stereo bug early on and we've loved it ever since. We know we're a bit fanatical, but in the best possible way.Hey, I'm Eric and I'm the main guy behind Edge Custom Audio. What started as a fun hobby back in the 90s soon became a business venture with a focus on gear. While I've enjoyed installing for many years, the satisfaction of the process was often overshadowed by the desire for the next best thing. The common theme with every completed project has been wondering "what if we had used that different amplifier" or "how would it sound with those other speakers". I've learned to embrace being a gearhead and appreciate the opportunity to share that with you.Our team here at Edge Custom Audio is all about quality. Quality products, quality service, and quality processes. We communicate personally because we're all just people after all. We ship in a safe and timely manner because we know you're excited to get your new gear. We stand behind everything we do because, well, it's the right way to operate. In the end, we know you're entrusting us with your hard-earned cash and we don't take that lightly.
