Its 4-ohm single voice coil configuration and 500-watt continuous power rating make it suitable for a dedicated mono amplifier channel. It is intended for compact subwoofer installations such as under-seat or rear-bench enclosures.\u003c\/p\u003e\u003cp\u003eThis Mille PRO shallow subwoofer is optimized for small sealed enclosures, with a manufacturer-developed sealed design using 14.2 liters (0.5 cu. ft.) of internal volume. That makes it a practical option when a traditional deep subwoofer box will not fit. The design can provide low-frequency support without requiring a large enclosure footprint.\u003c\/p\u003e\u003cp\u003eThe polypropylene cone and high-density flux ferrite magnet are paired with a 38 mm, six-layer copper voice coil. Hertz specifies 1,000 watts peak handling and a 25 Hz to 400 Hz frequency response. Its 83.5 dB sensitivity and 29 Hz resonant frequency help define the driver’s system requirements.\u003c\/p\u003e\u003cp\u003eHertz uses a dedicated spider and voice-coil support structure to move the magnetic assembly inward and preserve cone travel in a shallow format. The MPS250S4-1 has 20 mm of Xmech mechanical excursion and 16.8 mm Xmax. Its Air Intercooling Revolution design is intended to reduce air-compression-related limitations inside compact enclosures.\u003c\/p\u003e\u003cp\u003eThe subwoofer can be used in a sealed or reflex enclosure when built to Hertz’s published designs. A sealed enclosure favors a compact installation, while the published reflex design uses more space and is tuned for stronger output in its intended operating range. Pair it with an amplifier suited to a 4-ohm load and configure crossover settings appropriate for the rest of the vehicle audio system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow-Mount Format:\u003c\/strong\u003e 82.6 mm depth supports installations with limited enclosure depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W Continuous Handling:\u003c\/strong\u003e Supports amplification matched for 500 watts RMS at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 4-Ohm Voice Coil:\u003c\/strong\u003e Provides a straightforward load for compatible mono amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Sealed Enclosure:\u003c\/strong\u003e Designed for a 14.2 L \/ 0.5 cu. ft. sealed box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-Layer Copper Voice Coil:\u003c\/strong\u003e Supports thermal capacity during sustained bass playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Mesh Grille:\u003c\/strong\u003e Adds driver protection with a screw-less grille design.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MPS250S4-1 uses a die-cast aluminum frame, polypropylene cone, high-density flux ferrite magnet, and non-vented rear structure. It includes a robust mesh grille with black mounting screws.

Hertz publishes sealed and reflex enclosure designs for this model, both using 16 mm wood; the compact sealed design is the more space-efficient option. Use a compatible 4-ohm amplifier, secure the driver with the specified mounting hardware, and set the low-pass and subsonic filters according to the enclosure type.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631824494662,"sku":"MPS250S4-1","price":575.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71QCOHiV9zL_c45c0924-7436-4109-88c3-7c1672c46e38.jpg?v=1784383308","url":"https:\/\/audiowatt.store\/products\/hertz-mps250s4-1-10-shallow-4-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
