{"product_id":"hertz-mpbx300s2-1","title":"HERTZ MPBX300S2-1","description":"\u003cp\u003eThe Hertz MPBX300S2-1 is a loaded 12-inch ultra-shallow sealed subwoofer enclosure designed for vehicle audio systems with limited installation depth. It combines a shallow MPS 300 S2 subwoofer with a purpose-built enclosure, eliminating the need to design and build a separate box. Its compact height makes it a practical option for locations such as under or behind seating where a conventional deep enclosure may not fit.\u003c\/p\u003e\u003cp\u003eThis passive enclosure is intended for listeners who want meaningful low-frequency output while preserving usable cargo or cabin space. It presents a 2-ohm nominal load and handles 500 watts continuous power, so it should be paired with an amplifier that is stable at 2 ohms and appropriately power-matched. The sealed-box design is engineered for controlled bass response rather than requiring a large ported enclosure.\u003c\/p\u003e\u003cp\u003eThe MPBX300S2-1 uses Hertz 2S², or 2 Sides\/2 Sounds, placement flexibility. Install it up-firing for a more direct, defined presentation, or use the included leveling feet for down-firing placement when greater low-frequency extension is desired. This lets the enclosure adapt to different vehicle layouts and listening preferences without rebuilding the system.\u003c\/p\u003e\u003cp\u003eIts construction focuses on reducing enclosure-related resonance. The cabinet uses 15 mm wood panels, internal sound-absorbing material, and panel-to-panel bracing with solid corners. These details support the shallow subwoofer by helping the enclosure remain rigid and acoustically controlled in a compact footprint.\u003c\/p\u003e\u003cp\u003eConnection options are designed for straightforward integration into a subwoofer system. Hertz SSP, or Sub Smart Plug, provides both a Plug-\u0026amp;-Play terminal block and conventional push terminals for speaker-wire connection. A supplied screw-less mesh grille helps protect the driver, while the adjustable logo orientation supports either installation direction.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Loaded Subwoofer:\u003c\/strong\u003e Combines a 300 mm shallow subwoofer and sealed enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Shallow Sealed Cabinet:\u003c\/strong\u003e Fits applications with limited available installation height.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W Continuous Handling:\u003c\/strong\u003e Supports amplifier matching for substantial bass-system output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2S² Placement Design:\u003c\/strong\u003e Allows up-firing or down-firing installation choices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSSP Connection System:\u003c\/strong\u003e Offers Plug-\u0026amp;-Play and traditional push-terminal wiring options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRigid Wood Construction:\u003c\/strong\u003e Uses bracing and damping material to reduce resonance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe enclosure uses 15 mm wood construction with internal sound-absorbing material, panel-to-panel bracing, solid corners, and rounded exterior corners.
