Hertz MPBX250S2 10" Active Subwoofer Ultra-Shallow Sealed Enclosure

Maximum bass impact in minimum space - engineered for tight installations

The Hertz MPBX250S2 represents advanced subwoofer engineering, combining a high-performance 10-inch (250mm) driver with an ultra-shallow sealed enclosure optimized for space-constrained installations. This active subwoofer system delivers exceptional low-frequency performance while requiring minimal mounting depth, making it ideal for vehicles where traditional subwoofer boxes simply won't fit.

The innovative 2S² (2 Sides/2 Sounds) design allows users to select between down-firing configuration for extended low-frequency response or up-firing setup for enhanced punch and definition. Built with professional-grade 15mm thick panels and internal bracing, this system maintains structural integrity under high-power operation while minimizing unwanted resonances.

Key Specifications

• Driver size: 250mm (10-inch) high-excursion subwoofer
• Power handling: 500W RMS continuous / 1000W peak
• Impedance: 2 ohms for maximum power transfer
• Frequency response: 25-400Hz for deep bass extension
• Voice coil: 38mm (1.5") single coil design
• Enclosure depth: 118mm (4.65") ultra-shallow profile
• Weight: 10.8kg (23.8 lbs) complete system

Features & Benefits

• Ultra-shallow 118mm depth - Fits under seats, in tight boot spaces, and other constrained mounting locations where standard subwoofers cannot
• Dual firing orientation system - Switch between down-firing for maximum extension or up-firing for increased impact based on installation needs
• Robust 15mm panel construction - Eliminates cabinet flex and unwanted resonances during high-volume operation in mobile environments
• Internal sound-absorbing materials - Effectively increases acoustic volume while controlling internal reflections for cleaner bass reproduction
• SSP Smart Plug connectivity - Features both plug-and-play terminal block and traditional push terminals for versatile installation options
• 20mm mechanical excursion - Exceptional cone movement capability delivers deep, powerful bass from the compact 10-inch driver
• Professional internal bracing - Panel-to-panel reinforcement with solid corners ensures long-term structural stability under automotive stress

Frequently Asked Questions

**Will this fit under my car seats? ** At only 118mm deep, this ultra-shallow design fits most under-seat installations where traditional subwoofers won't.

**What's the difference between up-firing and down-firing modes? ** Down-firing extends low-frequency response while up-firing provides more punch and definition in the mid-bass region.

**Can I power this with a 500W amplifier? ** Yes, this 2-ohm subwoofer is designed to work optimally with 500W RMS amplifiers for maximum performance.

**Does the shallow design compromise bass output? ** No, the optimized enclosure design and internal damping materials maintain full bass performance despite the compact size.

**Is professional installation recommended? ** While DIY installation is possible, professional installation ensures optimal placement, wiring, and tuning for best results.
