Its single 2-ohm voice coil configuration is intended for use with an external subwoofer amplifier. The driver is engineered for installations where enclosure space is limited.\u003c\/p\u003e\u003cp\u003eIt is a practical choice for listeners building a compact bass upgrade in a trunk, cargo area, or under-seat-style custom enclosure where fitment allows. Hertz specifies enclosure designs beginning at 16 liters for this model. That compact-box focus helps simplify integration into systems that cannot accommodate a large subwoofer enclosure.\u003c\/p\u003e\u003cp\u003eThe CS 250 S2 handles 300 watts continuous power and 600 watts peak power. Its 2-ohm nominal impedance can be matched with an amplifier that is stable at 2 ohms. The 84 dB SPL sensitivity and 30 Hz resonance frequency provide useful design information when selecting amplification and enclosure parameters.\u003c\/p\u003e\u003cp\u003eHertz uses a polypropylene cone and a shaped dust cap developed through FEM simulation to help reduce low-frequency distortion. The 35 mm voice coil uses six layers of pure copper wire on a high-thermal-resistance glass-fiber support. Its magnetic-group geometry and airflow-focused design are intended to support controlled operation at higher excursion levels.\u003c\/p\u003e\u003cp\u003eThis subwoofer fits naturally into a system with a dedicated mono amplifier, low-pass filtering, and a properly built sealed enclosure. The manufacturer publishes a 16-liter sealed-box design with a 231 mm mounting hole. Solid push terminals accept speaker cable up to 8 AWG for straightforward connection in single- or multi-subwoofer installations.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300W Continuous Power:\u003c\/strong\u003e Supports amplifier matching around its 300-watt RMS rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 2-Ohm Voice Coil:\u003c\/strong\u003e Provides a 2-ohm nominal load for compatible amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Sealed-Box Design:\u003c\/strong\u003e Optimized for sealed enclosures starting at 16 liters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Uses a durable cone material for low-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-Layer Copper Voice Coil:\u003c\/strong\u003e Helps manage thermal demands during sustained operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 AWG Push Terminals:\u003c\/strong\u003e Accepts substantial speaker wire for secure amplifier connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe CS 250 S2 combines a polypropylene cone with a high-density-flux ferrite magnet and rubber protection around the magnetic assembly. Its 35 mm voice coil is wound on a glass-fiber support, while the high-strength ABS gasket is designed to accommodate the optional grille. The driver has a 270 mm overall diameter and a 115 mm mounting depth.\u003c\/p\u003e\u003cp\u003ePlan for a 231 mm mounting cutout and at least 115 mm of mounting-depth clearance behind the mounting surface. Hertz publishes a 16-liter sealed enclosure with 19 mm wood, 385 x 385 x 180 mm external dimensions, and damping material on the rear panel. Match it to an amplifier rated for a 2-ohm load, and use the published 15 Hz subsonic and 70-80 Hz low-pass filter guidance for that sealed-box design.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631722094662,"sku":"CS250S2","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71a70dsw9vL.jpg?v=1784379396","url":"https:\/\/audiowatt.store\/products\/hertz-cs-250-s2-10-2-ohm-component-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
