Description

Highlights

  • Mille PRO 12-inch shallow subwoofer for ultra-tight spaces
  • Exceptionally shallow depth: only 88 mm (3.46")
  • 500W RMS power and 1000W peak power
  • Optimized for ultra-compact sealed enclosures starting from 22.7 liters
  • Cone excursion 20% greater than traditional designs
  • Ingenious suspension system with dedicated support structure
  • Magnet assembly moved inward to reduce depth
  • Ideal for installation under the rear seats of pickup trucks

Description

Mille PRO shallow subwoofers were designed to achieve exceptional performance even when there is very little space available to install the subwoofer enclosure.

The MPS 300 S4 (12-inch) is optimized to work in ultra-compact sealed enclosures starting from just 22.7 liters (0.8 Cf). A typical example is a subwoofer enclosure under the rear seats of pickup trucks, where space – and height – are limited.

The Mille PRO subwoofer boasts an unprecedented depth-to-performance ratio thanks to the impressive cone excursion capability, which is 20% greater than traditional designs.

This exceptional objective was achieved through the ingenious design of the suspension system, featuring a dedicated support structure for the spider and voice coil. This solution allowed the magnet assembly to be moved inward, reducing depth while maximizing linear cone excursion.

  • Mille PRO 12-inch shallow subwoofer for exceptional performance in tight spaces
  • Exceptionally shallow depth: only 88 mm (3.46") for easy installation
  • 500W RMS power and 1000W peak power for deep bass
  • Optimized for ultra-compact sealed enclosures starting from 22.7 liters (0.8 Cf)
  • Ideal for installation under the rear seats of pickup trucks
  • Perfect for spaces where height is limited
  • Unprecedented depth-to-performance ratio
  • Cone excursion capability 20% greater than traditional designs
  • Ingenious suspension system with dedicated support structure for spider and voice coil
  • Magnet assembly moved inward to reduce depth
  • Maximization of linear cone excursion for optimal performance
  • 38 mm (1.5") voice coil for power and control
  • High flux density ferrite magnet for high motor force
  • Magnet size: 156 x 60 x 36 mm for optimal performance
  • Polypropylene cone for fast and controlled response
  • Linear excursion (Xmax) of 16.8 mm for significant air displacement
  • Mechanical excursion (Xmech) of 20 mm (0.79") for extreme performance
  • Frequency response: 25-400 Hz for low-frequency reproduction
  • Resonance frequency (Fs) of 23 Hz for ultra-deep bass
  • Qts of 0.42 ideal for sealed enclosures
  • Exceptional motor force (BL) of 18.7 T•m for optimal control
  • Sensitivity of 85 dB for optimal efficiency
  • 4-ohm impedance for compatibility with most amplifiers
  • Single Voice Coil for wiring simplicity
  • Robust construction weighing 6.64 kg for maximum durability
