Its dual 2-ohm voice-coil design gives installers wiring flexibility when matching the subwoofer to a suitable amplifier. It is intended for custom enclosure installations rather than direct factory-replacement use.\u003c\/p\u003e\u003cp\u003eWith 1200 watts RMS continuous power handling and 2400 watts peak power handling, the SS 15 D2 is designed for systems that require substantial low-frequency output. The large 380 mm cone and 88 dB sensitivity support strong bass performance in properly designed enclosures. It is a practical fit for enthusiasts building a dedicated amplified bass section.\u003c\/p\u003e\u003cp\u003eThe 75 mm (3-inch) dual voice coil uses a four-layer winding on a vented former to support heat management during demanding use. A large ferrite magnet assembly provides the motor strength needed to control the moving assembly. The result is a subwoofer built around power handling, excursion capability, and mechanical durability.\u003c\/p\u003e\u003cp\u003eIts non-pressed paper cone includes cotton fiber to balance low moving mass with rigidity, while the multilayer foam surround supports long cone travel. The progressive double-layer spider helps maintain consistent suspension behavior over time. Hertz rates maximum linear excursion at 15.4 mm.\u003c\/p\u003e\u003cp\u003eThe SS 15 D2 can be used in either sealed or reflex enclosures based on the desired system design. Hertz publishes an 80 L sealed enclosure alignment and a 120 L reflex enclosure alignment tuned to 38 Hz. Pair it with an amplifier and enclosure engineered for the selected final impedance and available vehicle space.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1200 W RMS Handling:\u003c\/strong\u003e Supports use with a properly matched high-power subwoofer amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Provides wiring options for compatible amplifier configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e75 mm Four-Layer Voice Coil:\u003c\/strong\u003e Uses a vented former to support thermal management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgressive Double-Layer Spider:\u003c\/strong\u003e Helps maintain suspension control through repeated excursion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultilayer Foam Surround:\u003c\/strong\u003e Supports the long cone travel needed for high-output bass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 AWG Push Terminals:\u003c\/strong\u003e Accept high-current speaker wire for a secure connection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SS 15 D2 combines a non-pressed paper cone with cotton fiber, a multilayer foam surround, oversized suspension components, and reinforced leadwires. Its ferrite motor measures 180 x 90 x 40 mm, and the driver has a total mounting depth of 210 mm. The basket is designed to support thermal dissipation and mechanical strength in high-output installations.\u003c\/p\u003e\u003cp\u003ePlan for a 353 mm (13.9-inch) mounting cutout and 188 mm (7.4-inch) installation opening depth, plus clearance behind the driver. Hertz specifies 80 L (2.83 cu. ft.) for its sealed design or 120 L (4.24 cu. ft.) for its reflex design, using 19 mm (0.75-inch) enclosure material. Wire the dual coils according to the amplifier's supported load and use speaker cable up to 12 AWG at the push terminals.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631858966598,"sku":"SS15D2","price":499.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71VAC6WVVFL.jpg?v=1784384030","url":"https:\/\/audiowatt.store\/products\/hertz-ss-15-d2-15-dual-2-ohm-spl-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
