Its dual 2-ohm voice-coil configuration gives installers useful wiring flexibility when matching the subwoofer to a compatible amplifier. With 600 watts RMS power handling, it is intended for a properly powered aftermarket bass upgrade.\u003c\/p\u003e\u003cp\u003eThis model is suited to listeners building a focused subwoofer system for music playback rather than simply adding a small amount of bass. Its 86 dB sensitivity and 23 Hz free-air resonance support deep bass extension when the driver is installed in an appropriate enclosure. Hertz provides both sealed and reflex enclosure designs for the MP 300 D2.3.\u003c\/p\u003e\u003cp\u003eThe pressed-pulp cone incorporates mineral powders to increase rigidity while keeping the moving assembly suited to controlled bass reproduction. Its V-cone profile is engineered to help the cone retain its shape through longer excursions. A Boundary Free IIR rubber surround expands the effective radiating area while maintaining the nominal 12-inch format.\u003c\/p\u003e\u003cp\u003eA 65 mm, four-layer CCAW voice coil is paired with a high-density flux ferrite motor for thermal handling and motor control. Venting behind the voice-coil winding and in the motor structure helps move air around the coil assembly. The driver has a rated linear excursion of ±16 mm and a mechanical excursion rating of ±26 mm.\u003c\/p\u003e\u003cp\u003eThe MP300D2-3 can be the foundation of a dedicated mono subwoofer channel in a larger aftermarket system. Its two 2-ohm coils can be wired in parallel for a 1-ohm nominal load or in series for a 4-ohm nominal load, subject to amplifier capability. Pair it with an amplifier selected for its 600-watt RMS rating and configure the enclosure and crossover settings for the intended application.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e600-Watt RMS Handling:\u003c\/strong\u003e Supports amplifier matching for a substantial dedicated bass channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Enables 1-ohm parallel or 4-ohm series wiring options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral-Loaded Pulp Cone:\u003c\/strong\u003e Adds cone rigidity for controlled low-frequency operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eV-Cone Profile:\u003c\/strong\u003e Helps the cone remain stable during high excursion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoundary Free Rubber Surround:\u003c\/strong\u003e Increases effective cone area within the 12-inch format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e65 mm CCAW Voice Coil:\u003c\/strong\u003e Uses a four-layer winding with motor ventilation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MP300D2-3 uses a high-density flux ferrite magnet, pressed-pulp mineral-powder cone, and high-purity IIR butyl-rubber surround. Its anti-resonant aluminum-alloy basket uses a six-spoke structure with venting beneath the spider. The spring terminal block accepts up to 8 AWG cable and includes a protective cover intended to reduce the chance of an accidental short circuit.\u003c\/p\u003e\u003cp\u003eUse the manufacturer mounting-hole diameter of 287 mm (11.30 inches) when planning the baffle cutout, and allow for the listed 187 mm (7.36 inches) mounting-depth dimension. Hertz specifies a 28 L (0.99 cu. ft.) sealed enclosure design with 19 mm (0.75 inch) material, while its reflex design requires more enclosure volume and port construction. Set the amplifier crossover appropriately; Hertz suggests a 70-80 Hz, 24 dB\/octave low-pass setting for its sealed-box design.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631780421702,"sku":"MP300D2-3","price":649.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/717wTfEqwKL.jpg?v=1784382680","url":"https:\/\/audiowatt.store\/products\/hertz-mp300d2-3-12-dual-2-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
