Its dual 2-ohm voice coils provide wiring flexibility for compatible mono or multi-channel amplification. It is intended for listeners building a system that needs substantial low-frequency output without moving to a larger woofer.\u003c\/p\u003e\u003cp\u003eRated for 600 watts continuous power and 1,200 watts peak power, this subwoofer is suited to an appropriately matched external amplifier. The dual 2-ohm configuration can be wired to a 1-ohm parallel load or a 4-ohm series load with one subwoofer. Proper amplifier load capability, gain setting, enclosure construction, and crossover setup remain important to system performance.\u003c\/p\u003e\u003cp\u003eThe pressed-pulp cone incorporates mineral powders to combine rigidity with damping. Hertz uses an exponential V-cone profile intended to help the cone maintain controlled piston-like behavior through its operating range. A Boundary Free IIR rubber surround increases available radiating area while retaining a compact nominal frame diameter.\u003c\/p\u003e\u003cp\u003eThe MP 250 D2.3 uses a 65 mm, four-layer CCAW voice coil and a high-density ferrite motor. Its TIL-P voice-coil former includes venting behind the winding to support heat dissipation. The published electro-acoustic specifications include a 30 Hz resonant frequency, 83.5 dB sensitivity, and ±17 mm Xmax.\u003c\/p\u003e\u003cp\u003eThis driver can be used in a manufacturer-specified 17 L sealed enclosure or a 22 L reflex enclosure. A sealed setup is the more compact option, while the reflex design follows Hertz's specified tuning and port dimensions. It is a component subwoofer, so an enclosure, amplifier, wiring, and installation hardware should be planned as part of the complete system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e600 W Continuous Power:\u003c\/strong\u003e Supports use with a suitably matched external amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Allows 1-ohm parallel or 4-ohm series wiring for one driver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral-Injected Pulp Cone:\u003c\/strong\u003e Combines a pressed-pulp diaphragm with mineral powders for rigidity and damping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoundary Free Surround:\u003c\/strong\u003e IIR rubber surround increases usable emission area within the nominal frame size.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e65 mm CCAW Voice Coil:\u003c\/strong\u003e Four-layer coil construction is designed for the published power rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-Spoke Alloy Basket:\u003c\/strong\u003e Aluminum alloy basket provides a rigid, vented mounting structure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MP 250 D2.3 is built around a high-density flux ferrite magnet, pressed-pulp mineral cone, and Boundary Free IIR rubber surround. Its six-spoke aluminum alloy basket includes venting beneath the spider, while the basket edge has a CNC-machined diamond-cut finish. The terminal block accepts up to 8 AWG speaker cable and includes a protective plastic cover.\u003c\/p\u003e\u003cp\u003eAllow for a 236 mm (9.29 in.) mounting cutout and 141 mm (5.55 in.) mounting depth when designing an enclosure. Hertz specifies a 17 L (0.60 cu. ft.) sealed enclosure or a 22 L (0.78 cu. ft.) reflex enclosure, each using 19 mm (0.75 in.) wood in its published examples. For one subwoofer, wire the coils in parallel only with an amplifier rated for a 1-ohm load, or wire them in series for a 4-ohm load.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631776817222,"sku":"MP250D2-3","price":549.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71A6zTH6fdL.jpg?v=1784382529","url":"https:\/\/audiowatt.store\/products\/hertz-mp-250-d2-3-10-dual-2-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
