The MPS 300 S2 shallow subwoofer is designed to deliver exceptional performance even in situations where space is limited for installing the subwoofer box.
Optimized to work in ultra-compact sealed boxes starting from as little as 22.7 liters (0.8 cubic feet), the MPS 300 S2 is an excellent choice for installations with space constraints, such as subwoofer enclosures under the rear bench of pickup trucks.
One of the key features that sets the MPS 300 S2 apart is its depth/performance ratio, which has never been achieved before. This is made possible by its impressive cone excursion capacity, which is 20% higher than traditional designs.
The ingenious suspension group design plays a vital role in achieving this exceptional target. It features a dedicated support structure for the spider and coil, allowing the magnetic group to move inwards. This reduction in depth maximizes cone linear excursion while maintaining performance.
Features:
1. Ultra-shallow overall depth
2. 500W continuous power handling
3. Optimized for extremely compact sealed enclosures of 20-24 liters (0.7-0.8 cubic feet)
4. Air Intercooling Revolution (A.I.R.) technology prevents air-compression-related limitations
5. Unrivalled mechanical excursion, with +20% compared to traditional designs
6. Six-layer copper voice coil (38mm/1.5 in.) ensures high thermal capacity
7. Non-vented rear design allows for reduced enclosure depth
8. Robust screw-less mesh grille included with black screws provided
9. Die-cast aluminum frame
10. Solid horizontal 8AWG spring-loaded terminals
