Tuned to 36 Hz with a 1.29 FT³ chamber, this enclosure delivers deep, punchy bass that turns every drive into a high-energy audio experience. Its single slot-port design optimizes airflow for tight, responsive lows that hit hard without distortion. Slim and designed for a behind-seat fit, it saves valuable cabin space while filling your truck with rich, full-range sound.
With a compact 4 1/2" mounting depth and a powerful 5 1/2" magnet, this enclosure delivers big, hard-hitting sound while keeping your setup low-profile. Constructed from 5/8" high-density MDF, it offers rugged durability and consistent acoustic performance on every American road. Wrapped in a tough trunk-liner carpet, it resists wear, spills, and fading while maintaining a clean, factory-inspired look that complements your truck interior.


Sealed with premium Titebond silicone and reinforced with wood glue, this enclosure locks in every vibration for distortion-free, powerful bass. A single binding post terminal makes installation quick, secure, and professional-grade. Its forward-firing design projects deep lows straight into your cabin, delivering an immersive audio experience on commutes, tailgates, or road trips. Built tough for real-world driving, it stays reliable through bumps, turns, and long miles while keeping your bass punchy and consistent.

Mille PRO shallow subwoofers have been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box. MPS 250 is optimized to work in ultra-compact sealed boxesstarting from only 22,7 Lt (0.8 Cf). 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.
