It is rated for 350 watts RMS and 700 watts peak power handling. Its 2-ohm configuration is intended for use with a compatible external amplifier.\u003c\/p\u003e\u003cp\u003eThis subwoofer is suited to listeners building a compact sealed-box bass system without moving to a large enclosure. Hertz specifies enclosure designs starting at 32 liters for the CS 300 S2. The recommended sealed alignment supports a practical installation in many vehicle types.\u003c\/p\u003e\u003cp\u003eThe CS300S2 uses a polypropylene cone and dust-cap geometry developed with FEM simulations to help reduce low-frequency distortion. Its 86.5 dB sensitivity and 25 Hz free-air resonance are supported by a 12.5 mm linear excursion rating. These characteristics make it appropriate for systems focused on controlled bass reproduction.\u003c\/p\u003e\u003cp\u003eA 35 mm voice coil is wound in six layers of pure copper over a high-temperature glass-fiber support. Hertz also uses a fluid-dynamic ventilation approach through the spider support and basket vents to reduce air-compression effects at higher excursion. The compact magnetic assembly and reduced mounting depth help support space-conscious custom enclosures.\u003c\/p\u003e\u003cp\u003eThe CS300S2 can be used as a single-subwoofer upgrade or incorporated into a multi-subwoofer system, provided the final load is compatible with the amplifier. Solid push terminals accept cable up to 8 AWG for straightforward wiring. An optional Hertz CG 300 grille can be added when cone protection is needed.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e350 Watt RMS Rating:\u003c\/strong\u003e Supports amplifier matching for continuous-power operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm SVC Design:\u003c\/strong\u003e Provides a single 2-ohm nominal load per subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Polypropylene Cone:\u003c\/strong\u003e Designed for durable low-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-Layer Copper Voice Coil:\u003c\/strong\u003e Uses copper winding on a glass-fiber former.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Sealed-Box Design:\u003c\/strong\u003e Optimized for enclosures starting at 32 liters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 AWG Push Terminals:\u003c\/strong\u003e Accept substantial speaker cable without ring terminals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe CS300S2 combines a high-density flux ferrite magnet with a polypropylene cone, rubber-protected magnetic assembly, and high-strength ABS mounting gasket. Its magnetic-group geometry and moving components are engineered for controlled operation at high excursion. The gasket is designed to accept the optional CG 300 protective grille.\u003c\/p\u003e\u003cp\u003eUse this passive subwoofer with an external amplifier that is stable at a 2-ohm load and appropriately matched to its 350-watt RMS rating. Hertz provides a 32-liter sealed-box reference design with a 281 mm mounting hole and 19 mm enclosure material. For that sealed alignment, Hertz suggests a 15 Hz subsonic filter and a 60-70 Hz low-pass filter, both at 24 dB per octave.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631723339846,"sku":"CS300S2","price":329.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/710AJMHzgAL.jpg?v=1784379504","url":"https:\/\/audiowatt.store\/products\/hertz-cs300s2-12-2-ohm-single-voice-coil-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
