Its single 4-ohm voice coil configuration makes it a straightforward choice for a dedicated subwoofer amplifier channel or a bridged amplifier setup. It is intended for custom sealed enclosures with internal volume starting at 10 liters.\u003c\/p\u003e\u003cp\u003eThis Prima-series subwoofer addresses installations where mounting depth and enclosure space are limited, such as compact trunks, underfloor areas, and vehicle-specific build locations. Its 120 mm ultra-low-profile design helps reduce the space required behind the driver. Basket ventilation beneath the spider also eliminates the need for a central pole vent, helping support close placement to an enclosure’s rear wall.\u003c\/p\u003e\u003cp\u003eRated for 400 watts continuous power and 800 watts peak power, the APS 10 S4S is built for properly amplified bass duty in a sealed system. Its 4-ohm nominal impedance and single voice coil simplify amplifier matching compared with multi-coil wiring arrangements. The driver uses a 60 mm voice coil, a high-density-flux ferrite motor, and a water-repellent pressed-paper cone.\u003c\/p\u003e\u003cp\u003eAudison engineers the cone, dustcap, and basket geometry to support long linear excursion while maintaining a compact mounting profile. The driver has 12.6 mm Xmax and an 18 mm mechanical excursion specification. Its motor assembly is optimized using finite-element modeling for control under high-power, high-excursion operating conditions.\u003c\/p\u003e\u003cp\u003eThe APS 10 S4S is a component subwoofer, so a separate enclosure, amplifier, wiring, and installation hardware are needed to complete a system. It can serve as a compact bass upgrade alongside factory or aftermarket speakers when installed in a correctly sized sealed enclosure. A steel mesh grille and plastic gasket are included to help protect the driver and finish the installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Shallow Design:\u003c\/strong\u003e Provides compact bass capability with a 120 mm ultra-low profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400W Continuous Rating:\u003c\/strong\u003e Supports sustained subwoofer power handling in a properly configured system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 4-Ohm Voice Coil:\u003c\/strong\u003e Simplifies wiring to a compatible 4-ohm amplifier channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed-Enclosure Optimization:\u003c\/strong\u003e Designed for sealed enclosures starting at 10 liters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Repellent Paper Cone:\u003c\/strong\u003e Uses treated pressed paper for the moving cone assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Protection Grille:\u003c\/strong\u003e Steel mesh grille helps protect the installed subwoofer driver.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe APS 10 S4S combines a high-density-flux ferrite magnet with a 60 mm voice coil and water-repellent pressed-paper cone. Its basket includes vents beneath the spider, while the shallow geometry is designed to retain excursion capability in a compact format. The supplied steel mesh grille and plastic gasket provide practical finishing and protection components.\u003c\/p\u003e\u003cp\u003eInstall this driver in a custom sealed enclosure with at least 10 liters of volume, allowing for the driver’s 1.12-liter displacement during enclosure planning. Verify the 270 mm outside diameter, 233 mm Dimension B, and 88 mm mounting-depth measurement against the available mounting location before cutting. Use an amplifier that is stable at 4 ohms, set gains carefully, and configure the system’s crossover and enclosure construction for subwoofer use.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":45614230732870,"sku":"APS10S4S","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71Exi-yjeZL.jpg?v=1784363040","url":"https:\/\/audiowatt.store\/products\/audison-aps-10-s4s-10-4-ohm-shallow-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
