Hertz Mille Pro 12-inch Ultra-Shallow Sealed Subwoofer Enclosure - MPBX 300 S2

Hertz MPBX 250 S4 Mille Pro 12-inch Ultra-Shallow Sealed Subwoofer Enclosure

MPBX 300 S2 ultra-shallow sealed enclosure is specifically optimized to deliver all the MPS 300 S2 subwoofer performances. The enclosure structure features incomparable robustness thanks to 15 mm (0.59 in.) wood thickness. Internal sound-absorbing material virtually increases the box's volume and reduces acoustic resonances. Panel-to-panel internal bracing with solid corners minimizes resonances and round corners ease the placement. 2S² (2 Sides/2 Sounds) design provides the ability to choose between Down-Firing mounting, through supplied feet with Hook-and-loop inserts, to increase the low-frequency extension, and Up-Firing installation to obtain more punch and definition. SSP (Sub Smart Plug) features both Plug-&-Play terminal block and traditional push terminals providing bulletproof connection and quick release.

Key Features

• eID (Elettromedia Identification)
  The exclusive technology providing the traceability of the Mille.3 products from their birth on. Once the test phase has been passed, the code linked to destination country/market is applied. When purchasing the product, by scanning the code, the user can check through the web the information about the product and can log into the registration page.
• Air Innovative Route
  Hertz R&D has developed the proprietary AIR (Air Intercooling Revolution) technology, optimizing the fluid dynamics inside the voice coil inner chamber and the magnetic group to minimize the internal compression of air and maximize cooling capacity.
• Mille PRO shallow subwoofers have been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.
  The subwoofers are optimized to work in ultra-compact sealed boxes starting from only 14 Lt (0.49 Cf) for 10′ models (MPS 250) and 22,7 (0.8 Cf) for 12’models (MPS 300). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space – and the height – are limited.The new MPS (Mille PRO Shallow) subwoofers 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 smart 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.
• Air
  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.
  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.
• Mille PRO Shallow Subwoofer Boxes
  Mille PRO ultra-shallow sealed enclosure are specifically optimized to deliver all the MPS subwoofer performances providing breathtaking low frequency from a box that is only 160 mm (6.3 in.) deep for MPBX 250 S2 and 175 mm (6.89) for MPBX 300 S2.
  They are the Ideal choice to be installed under the rear bench of pickup trucks and generally where the space – and the height – are limited.
  Hertz R&D department meticulously design the perfect sealed enclosure for MPS 250 S2 and MPS 300 S2 shallow-subwoofer using the most advanced technologies and massive in-car listening sessions to fine-tune the sound.
  The panel-to-panel internal bracing on all sides of the box featuring solid corners minimize resonances. The internal sound-absorbing material virtually increase the volume of the box and further damp acoustic resonances. The 15 mm (0,59 in.) wood thickness provides an incomparable robustness.
  2S² (2 Sides/2 Sounds) design provides the ability to choose between up-firing install to obtain more punch and definition and down-firing mounting, through supplied feet with Hook-and-loop inserts , to increase the low-frequency extension.
  Thanks to SSP (Sub Smart Plug), MPBX feature both Plug-&-Play terminal block and traditional push terminals providing bulletproof connection and quick release.
